run before the main timeline is started.  Also changed the scheduler
to load events before adding the TIME START events so we can add setup
events before the main timeline.

making into the eventlist.

Bring linktest in line with the new event system world order and do some
generic cleanup.  I'm pretty sure I broke backwards compatibility with
old disk images though...

	* configure, configure.in: Remove linktest.h.in from the list of
	template files.

	* event/linktest/GNUmakefile.in: Don't make subdirectories for
	executables since it can mess up the dependencies.  Don't install
	tb_compat.tcl stuff anymore.  Check for '/usr/local/bin/pathrate'
	and friends, and print out a warning if they are not found.  Make
	a version file for the linktest daemon.

	* event/linktest/linktest.c: Only subscribe to the events we care
	about 'STOP/KILL'.  Subscribe to TIME START events and kill any
	linktests that are in progress.  Send events through the local
	elvind instead of running tevc.

	* event/linktest/linktest.pl.in: Don't run the modified NS anymore
	to generate the topology file, use gentopofile to do that.  Send
	COMPLETE events to indicate that the tests were finished instead
	of STOP so it works with event-sequences.  Use emulab-sync to
	report errors between linktest daemons.  In addition to sending
	REPORT events, send LOG events to the SIMULATOR agent so the
	messages end up in the report e-mail.  Fix wait_all so it collects
	child processes immediately and doesn't leave zombies lying
	around.  Make the static route test work with topologies that
	aren't fully connected.  Change ownership of the linktest error
	files from root to the swapper.  Bump latency tolerance up to
	2.5ms.

	* event/linktest/ltevent.c: Use event_schedule instead of
	event_notify so the events go through the scheduler.

	* event/linktest/run_linktest.pl.in: Wait for COMPLETE events
	insetad of STOPs.

	* event/linktest/linktest.h.in: Removed.

	* event/sched/error-record.c: Include linktest error output in the
	report e-mail.

	* event/sched/event-sched.c: Linktest now sends COMPLETE events
	for START events.

	* tbsetup/gentopofile.in, tmcd/common/config/rc.topomap: Piggy
	back the generation and management of the linktest config file
	onto the generation of the topomap.

	* tbsetup/ns2ir/sim.tcl.in: Add "linktest" event to the Simulator
	object that runs linktest at level 3 (latency, static routing, and
	loss).

	* tmcd/common/libsetup.pm: Add TMLTMAP constant that contains the
	path to the node local linktest config file.

	* tmcd/common/rc.linktest: Pass '-u' option to the linktest daemon
	so it knows what user should to change ownership of files to.

	* tmcd/freebsd/jail/mkjail.pl: Copy the linktest config file
	(ltmap) into the jail.

ElabInElab experiment loads the current elabinelab.ns file from the
lib directory.

Otherwise:

	tb-elab-in-elab-topology withrouter

will load elabinelab-withrouter.ns from the lib directory.

some details can be found in the advanced tutorial that I wrote up.
See this link:

http://www.emulab.net/tutorial/docwrapper.php3?docname=advanced.html#Tracing

The basic idea is that each virt_lan entry gets a couple of new slots
describing the type of tracing that is desired.

  traced tinyint(1) default '0',
  trace_type enum('header','packet','monitor') NOT NULL default 'header',
  trace_expr tinytext,
  trace_snaplen int(11) NOT NULL default '0',
  trace_endnode tinyint(1) NOT NULL default '0',

There is a new physical table called "traces" that is a little bit
like the current delays table. A new tmcd command returns the trace
configuration to the client nodes (tmcd/common/config/rc.trace).

The delays table got a new boolean called "noshaping" that tells the
delay node to bridge, but not set up any pipes. This allows us to
capture traffic at the delay node, but without much less overhead on
the packets.

The pcapper got bloated up to do packet capture and more event stuff.
I also had to add some mutex locking around calls into the pcap
library and around malloc, since the current setup used linuxthreads,
which is not compatable with the standard libc_r library. I was
getting all kinds of memory corruption, and I am sure that if someone
breathes on the pcapper again, it will break in some new way.

Event system documentation and tweaks:

	* event/sched/event-sched.c: The snapshot event got left out of
	the list of events that send back a complete event.  If a top
	level sequence stops with an error, automatically send a report.

	* event/sched/group-agent.c, event/sched/timeline-agent.c: When
	handling a complete event, return true if the event was consumed.

	* event/sched/node-agent.cc: Clean the "/local/logs" loghole on
	the node before taking a snapshot of the disk image.

	* event/sched/simulator-agent.cc, event/sched/simulator-agent.h:
	Made send_report non-static so it can be called when a sequence
	errors out.  Actually check the clear flag when dumping report
	data.

	* lib/libtb/tbdefs.c: Add a comment about updating the event
	scheduler when a new object type is added.

	* tbsetup/ns2ir/sim.tcl.in: Check the OSIDs passed to the "reload"
	and "snapshot-to" events.

	* utils/loghole.1: Mention early and often the directories that
	gets sync'd.  Document the 'change' action and new options for
	'clean'.

	* utils/loghole.in: Use rsync's '--include-from' option so we
	don't have to run rsync separately for each directory.  Add a
	'change' action that lets people mess with the metadata of an
	existing archive.  Make the 'clean' action also remove log files
	on the nodes.  Only rsync node's whose OS's support ssh.  Grab
	logs from delay nodes.

	* www/tutorial/advanced.html: Update the program agent examples to
	use the new form.

	* www/tutorial/eventsystem.html: First cut at an event system
	reference manual that includes sequences, timelines, and other
	new features.

	* www/tutorial/loghole.html: Just a pointer to the man page on ops
	for now.

	* www/tutorial/nscommands.html: Add a section about capturing
	parameters from the 'opt' array.

	* xmlrpc/emulabserver.py.in: Add an osid.info() method that
	returns information about a single OSID.

Add topography as an event object type, we use this to notify applets
about dynamic obstacles.  Some event-sched fixes are also included.

	* lib/libtb/tbdefs.h, lib/libtb/tbdefs.c: Add TOPOGRAPHY object
	and CREATE event.

	* robots/emc/emcd.c: Some cleanup for the events that get sent for
	dynamic obstacles.

	* tbsetup/ns2ir/node.tcl, tbsetup/ns2ir/sim.tcl.in,
	tbsetup/ns2ir/topography.tcl: Add Topography's to the virt_agents
	table.

	* event/sched/error-record.c: Fix the format for the filenames
	generated by the program-agent.

	* event/sched/event-sched.c: Mark the start of TIME, change how
	rmcd/vmcd get restarted, and fix the ordering of some events on
	startup.

	* event/sched/simulator-agent.h, event/sched/simulator-agent.cc:
	Record when TIME starts, change how the report is generated, and
	the current time to log messages.

	* event/sched/rpc.h, event/sched/rpc.cc: Add the "virtual"
	topography name to the emcd.config, it's used when sending events
	concerning dynamic obstacles.

for the inner elab.

	tb-set-elabinelab-cvstag dist-foo

Will result in this branch getting checked out from the mirrored repository
(updated nightly) on boss and sent back to the node, instead of the usual
source tarball that we keep in /usr/testbed/src (still the default
behaviour if no tag is specified. You can also do this if you like:

	tb-set-elabinelab-cvstag HEAD

which of course is a special tag to CVS.

Mote and robot related stuff.  The main thing is the addition of relay
capabilities to capture and related things.

	* GNUmakefile.in: Add the capture and tip subdirectories to the
	client and client-install targets.

	* configure, configure.in, config.h.in: Detect srandomdev() for
	capture and add "mote/newmote" script.

	* capture/GNUmakefile.in, capture/capture.c: Add "relay"
	capabilities to capture.

	* capture/capquery.c: Query the capserver for the relay receiver's
	port number.

	* capture/capserver.c: Small hack to return the port number
        for a node.

	* db/libdb.pm.in, db/xmlconvert.in: Add virt_tiptunnels table.

	* event/program-agent/program-agent.c: Change log file names to
	something a little more user-friendly.  Add a "MODIFY" event
	handler that lets the user set agent attributes (command, tag,
	timeout) without having to run a program.

	* event/sched/GNUmakefile.in, event/sched/console-agent.cc,
	event/sched/console-agent.h, event/sched/event-sched.c: Add
	console agents that can be used to snapshot a section of the
	capture log file.

	* event/sched/node-agent.cc: Some minor cleanup.

	* event/sched/simulator-agent.cc, event/sched/simulator-agent.h:
	Add the config data to the report mail.  Add a "RESET" event
	handler that runs "loghole clean".  Save the report mail in a file
	so it gets archived with the rest of the logs.

	* lib/libtb/tbdefs.h: Add CONSOLE object type.

	* mote/GNUmakefile.in, mote/newmote: Add newmote script, just a
	quick hack to add motes to the DB.

	* mote/tbuisp.in: Add another backend for loading motes through
	their relay capture server.

	* robots/mtp/mtp_dump.c: Dump the min/max values for x and y,
	handy for figuring out the bounds of the camera.

	* sql/database-fill.sql: Change the RELOAD-MOTE/SHUTDOWN ->
	ALWAYSUP/SHUTDOWN mode transition to ALWAYSUP/ISUP since stated
	doesn't seem to run triggers after a state change by a mode
	transition.

	* tbsetup/tbreport.in: Change the ordering of the eventlist so it
	displays event-sequences appropriately.

	* tbsetup/ns2ir/GNUmakefile.in, tbsetup/ns2ir/console.tcl,
	tbsetup/ns2ir/node.tcl, tbsetup/ns2ir/parse.tcl.in,
	tbsetup/ns2ir/sim.tcl.in: Add a "console" agent that represents
	the serial console for a node.

	* tbsetup/ns2ir/sequence.tcl: Add an "append" method so it is
	easier to build sequences dynamically.

	* tbsetup/ns2ir/topography.tcl: Make checkdest available to
	regular users.

	* tip/GNUmakefile.in, tip/tiptunnel.c: Add support for uploading a
	file to a relay version of capture and exporting the end
	connection as a pty.

	* tmcd/decls.h, tmcd/common/libsetup.pm: Bump version number since
	the dosubnodelist change is not backwards compatible.

	* tmcd/tmcd.c: Make dosubnodelist and dosubconfig callable even
	when a node isn't allocated.  Add dotiptunnels command that
	returns which serial consoles are to be mounted on a node.  Add
	mote version of subconfig that returns information needed to
	startup the relay version of capture.

	* tmcd/common/bootsubnodes: For motes, startup the relay version
	of capture (XXX stargate specific).

	* tmcd/common/libsetup.pm, tmcd/common/libtmcc.pm,
	tmcd/common/config/rc.config, tmcd/common/config/rc.tiptunnels:
	Client side changes for mounting another nodes serial line.

	* tmcd/common/rc.bootsetup: Always boot the subnodes, even when
	free.  This is used for motes since their capture needs to be up
	for reloading at the time.

	* tmcd/linux/ixpboot: Shuffle some code around so the script
	doesn't fail if the ixp isn't allocated.

	* utils/loghole.in: Add "digest.out" and "report.mail" as global
	logs to be saved in archives and display the "report.mail" file
	when showing a loghole archive.

	* xmlrpc/emulabserver.py.in: Scrub more of the return values to
	get rid of "None"s.

event.

Checkin some changes related to experiment automation and vnode feedback:

	* configure, configure.in: Add sensors/canaryd/feedbacklogs
	template.

	* db/libdb.pm.in, db/xmlconvert.in: Add "virt_user_environment"
	table that holds environment variable names and values.

	* event/lib/event.c: Allocate memory of the right size for
	event_notifications.

	* event/program-agent/GNUmakefile.in: Add version.c file and
	add install targets for the man page.

	* event/program-agent/program-agent.8: Man page describing the
	program-agent daemon.

	* event/program-agent/program-agent.c: Add a bunch of convenience
	features: let the user specify the working directory for commands;
	save output to separate files on every invocation of an agent; let
	the user specify a timeout for a command; make the set of
	environment variables sane and add vars given in the NS file in
	the opt array; a "status" file containing process information is
	written out when children are collected.  Internal changes: child
	processes are collected immediately, instead of waiting for the
	next START event, so we can send back COMPLETE events; the daemon
	now runs with a real-time priority, to increase the chances of
	receiving events.

	* event/proxy/evproxy.c: Made it bidirectional so the
	program-agent's COMPLETE events make it back to the scheduler.

	* event/sched/error-record.c: Change the default log directory.

	* event/sched/event-sched.h, event/sched/event-sched.c: Setup an
	environment similar to a program-agent to run the user's log
	digester.

	that runs create_image for the node.

	* event/sched/simulator-agent.h, event/sched/simulator-agent.cc:

	* event/sched/timeline-agent.c: Accept the RUN event as well as
	the START event.

	* os/GNUmakefile.in: Install the install-tarfile.1 man page.

	* os/install-tarfile: Automatically chown/chgrp any files that do
	not have valid user or group IDs, the new owner will be the user
	that swapped in the experiment.  Include the install directory in
	the DB file.  Add a "list" mode that just dumps what files have
	been installed and where.  Add a "force" option so the user can
	forcefully install the file, even though the DB says its already
	there.

	* os/install-tarfile.1: Man page describing the install-tarfile
	tool.

	* os/syncd/GNUmakefile.in: Install man pages on ops.

	* sensors/canaryd/GNUmakefile.in: Link canaryd statically and
	install "feedbacklogs" tool.

	* sensors/canaryd/canaryd.c: Dump dummynet pipe data.

	data from canaryd log files.

	* sensors/slothd/GNUmakefile.in: Install digest-slothd on ops.

	* sensors/slothd/digest-slothd: Fix some bugs and write out an
	"alert" file with all the nodes/links that were overloaded.

	* tbsetup/os_load.in, tbsetup/libosload.pm.in: Add "waitmode"
	argument that lets you specify that you want to wait for the disk
	to finish loading and/or wait for the node to come back up in the
	new OS.

	* tbsetup/power.in: Remove debugging printf.

	* tbsetup/ns2ir/node.tcl, tbsetup/ns2ir/program.tcl,
	tbsetup/ns2ir/sequence.tcl, tbsetup/ns2ir/sim.tcl.in: Fix some
	quoting problems with event-sequences.  Add -expected-exit-code
	and -tag options to the "$program run" event.  Add -digester to
	the "$ns report" event that lets the user specify a program to run
	to digest the log files.

	* tbsetup/ns2ir/tb_compat.tcl.in: Change the initial scaling
	factor for feedback nodes to 1%, instead of 100%.

	* tmcd/tmcd.c, tmcd/common/libtmcc.pm: Add "userenv" command that
	returns the values in "virt_user_environment".  Return new program
	agent fields: dir, timeout, and expected_exit_code.

	* tmcd/common/GNUmakefile.in: Install rc.canaryd.

	* tmcd/common/bootvnodes: Add hack to boost the program-agents to
	a real-time priority, they can't do it from inside the jail.

	* xmlrpc/emulabserver.py.in: Add "virt_user_environment" table.
	Order the eventlist by "idx" and time, needed for sequences.  And
	removed unnecessary nologin checks.

Robot-related improvements based on feedback from Sid:

	* event/sched/event-sched.h, event/sched/event-sched.c,
	event/sched/rpc.h, event/sched/rpc.cc: Send a notification of the
	start of event time and timelines.  Add a '-r' option that forces
	it to use the default rpc path (so dan can use a custom
	scheduler/rmcd/etc on ops).

	* robots/GNUmakefile.in, robots/emc/GNUmakefile.in,
	robots/mtp/GNUmakefile.in, robots/primotion/GNUmakefile.in,
	robots/rmcd/GNUmakefile.in, robots/vmcd/GNUmakefile.in,
	robots/tbsetdest/tbsetdest.cc: Add a control-install target.

	* robots/primotion/garcia-pilot.cc: Take out some experimental
	code.

	* robots/primotion/dashboard.hh, robots/primotion/dashboard.cc,
	robots/primotion/pilotClient.cc, robots/primotion/wheelManager.hh,
	robots/primotion/wheelManager.cc: When doing a COMMAND_STOP, make
	sure we only send one update packet, an idle or an abort.  Also
	send back the actual distance travelled/pivoted.

	* robots/tbsetdest/tbsetdest.cc: Don't output setdest event's with
	a speed of zero.

	* tbsetup/eventsys_control.in: When replaying/stopping, clear the
	start of event time for the experiment.

	* tbsetup/power_mail.pm.in: Decrease the threshold used to tell if
	a node has been power cycled "recently".

	* tbsetup/ns2ir/node.tcl, tbsetup/ns2ir/sim.tcl.in: Bah, backout
	last change, orientation is supposed to be in degrees at these
	points.  Also, when automatically picking the sync server, don't
	use nodes that are subnodes.

	* tmcd/common/bootsubnodes: Send an ISUP for motes.

	* www/moteleds.php3: Show the mote node names instead of the
	robots.

	* www/powertime.php3: Add option to mark nodes as powered off.

	* www/robotmap.php3: Display the elapsed time for the overall
	event time and for each active timeline.

	event_notification creation functions that get used in
	event-sched.

	* event/sched/event-sched.c, event/sched/rpc.h,
	event/sched/rpc.cc: Sync the start of event time with the
	robots reaching their initial positions.  This is done by
	creating a master event-sequence that takes care of sending
	the SETDEST events and then starting the Simulator timeline.

	* mote/tbuisp.in: Use node_reboot instead of ssh'ing in.

	* robots/GNUmakefile.in: Don't build tbsetdest if ulsshxmlrpcpp is
	not available.

	* robots/emc/loclistener.in: Clear the destination values for a
	node when it reaches its destination.

	* robots/primotion/garcia-pilot.cc,
	robots/primotion/pilotClient.cc: Some cleanup and debugging.

	* robots/primotion/wheelManager.cc: Check the rear sensors for
	obstructions and then decide which way to pivot.

	* tbsetup/os_setup.in: Removed the robot hack used when deciding
	which nodes to reconfig/reboot.  Added a robot hack to avoid
	rebooting a robot whose mote is being os_load'd, since it would
	interrupt tbuisp which does the reboot anyways.  Also fixed a
	small typo.

	* tbsetup/ns2ir/node.tcl, tbsetup/ns2ir/sim.tcl.in: Oops, forgot
	to convert degrees to radians.

	doing the install.

	* tmcd/linux-sg/rc.stargate: Start garcia-pilot.

	* vis/floormap.in: Add options for showing the camera bounds,
	obstacle exclusion zones, and displaying vnames instead of pnames.

	* www/ledpipe.php3: Finally figured out how to use a socket
	instead of popening a perl script.

	* www/robotmap.php3: Add checkboxes for displaying/not displaying
	the camera bounds and obstacle exclusion zones.  Add a legend
	showing what actual vs. destination points are.  Pass pid/eid
	through to vis/floormap if it is given.

	* www/showexp.php3: Add a "Robot Map" link to experiments that
	have allocated garcias.

	* www/floormap/map_legend_node.gif,
	www/floormap/map_legend_node_dst.gif: Icons used by the robot map
	legend.

	* www/floormap/robots-4.jpg: Added an obstacle around the entryway
	so people are slightly less likely to trip over the robots.  Added
	a coordinate system legend to the top left corner.

	* www/tutorial/mobilewireless.php3: Add links to David's movie of
	the robot making its way around the pillar.

	* www/tutorial/robot_anim.gif: A nifty gifanim clip of the robot
	movie.

	* xmlrpc/emulabserver.py.in: Pull the camera data from the DB,
	instead of returning hardcoded stuff.

	tb-set-delay-capacity 1

Will override the default delay capacity as specfied in the node_types
table for each node type, and set it for all types when generating the
ptop file.

This is a big stick, to be used with caution, as it will effectively
double the number of nodes used for delay nodes (withing an experiment).

Robot related stuff: power via e-mail, client-install fixups, checking
coords against camera boundaries.

	* configure, configure.in: Add tbsetup/power_mail.pm to the list

	* tbsetup/os_setup.in: Don't skip reboot of robots anymore.

	* tbsetup/power.in: Add special case for a power_id of "mail",
	which calls into the power_mail.pm backend.

	* tbsetup/power_mail.pm.in: E-mail backend for power, it sends an
	e-mail to tbops and waits for the outlets.last_power value to be
	updated from the power.php3 web page.

	* tbsetup/ns2ir/parse-ns.in: Add the contents of the cameras table
	to the TBCOMPAT namespace.

	* tbsetup/ns2ir/sim.tcl.in: More checking of "setdest" inputs.

	list of virtual tables.

	* event/lib/event.h, event/lib/event.c, event/lib/tbevent.py.tail:
	Add event_stop_main function to break out of the event_main()
	loop.  Add timeline to the address tuple.

	* event/sched/GNUmakefile.in, event/sched/error-record.h,
	event/sched/error-record.c, event/sched/event-sched.8,
	event/sched/event-sched.h, event/sched/event-sched.c,

	event/sched/simulator-agent.h, event/sched/simulator-agent.c,
	event/sched/timeline-agent.h, event/sched/timeline-agent.c:
	Updated event scheduler, not completely finished, but well enough
	along for the robots.

	* lib/libtb/GNUmakefile.in, lib/libtb/popenf.h,
	lib/libtb/popenf.c, lib/libtb/systemf.h, lib/libtb/systemf.c: Add
	some handy versions of system/popen that take format arguments.

	* lib/libtb/tbdefs.h, lib/libtb/tbdefs.c: Add some more event and
	object types.

	* tbsetup/assign_wrapper.in: Add the virt_node_startloc building
	to desires string for a node.

	* tbsetup/ptopgen.in: Add a node's location to the feature list.

	* tbsetup/tbreport.in: Display the timeline/sequence an event is a
	part of.

	* tbsetup/ns2ir/GNUmakefile.in: Add timeline, sequence, and
	topography files.

	* tbsetup/ns2ir/node.tcl: Add initial position for nodes and allow
	them to be attached to "topographys".

	* tbsetup/ns2ir/parse-ns.in: Make a hwtype_class array with a
	node_type's class.  Make an 'areas' array that holds the
	buildings where nodes are located.  Make an 'obstacles' table
	with any obstacles in the building.

	* tbsetup/ns2ir/parse.tcl.in: Move named-args function from
	tb_compat.tcl to here.  Add reltime-to-secs function that converts
	time given in a format like "10h2m1s" to a seconds value, used in
	"$ns at" so its easier to write time values.  Add "K", "Kb", and
	"Kbps" as possible units for bandwidth (only the lowercase
	versions were available before).

	* tbsetup/ns2ir/program.tcl: Add "dir" and "timeout" attributes,
	although they don't go anywhere at the moment.

	* tbsetup/ns2ir/sequence.tcl, tbsetup/ns2ir/timeline.tcl,
	tbsetup/ns2ir/topography.tcl: Initial versions.

	* tbsetup/ns2ir/sim.tcl.in: Add support for timelines and
	sequences.  Add 'node-config' method to change the default
	configuration for nodes produced by the Simulator object.  Send an
	initial MODIFY event to any trafgen objects so their configuration
	gets through, even when there are no start/stop events.  Move
	event parsing to the 'make_event' method.

	* utils/loghole.1, utils/loghole.in: Loghole utility, used for
	retrieving logs from experimental nodes and creating archives of
	the logs.

	* xmlrpc/emulabclient.py.in: Escape any strange characters in the
	output field.

	* xmlrpc/emulabserver.py.in: Add virt_node_startloc to the list of
	virtual_tables.  Add emulab.vision_config and
	emulab.obstacle_config methods for getting information pertaining
	to the robots.  Change the OSID listing to include more fields.
	Add a "physical" aspect to experiment.info to get information
	about the physical nodes.  Add parent field to the events in the
	array returned by eventlist.  Add sshdescription to get extra
	information needed to log into a vnode.  Add node.statewait so you
	can wait for nodes to come up.

	source tb_compat.tcl
	set ns [new Simulator]

	tb-elab-in-elab 1
	tb-set-inner-elab-eid two-simple
	tb-set-security-level Red

	$ns run

tbsetup/ns2ir/elabinelab.ns has all the goo, which is sourced from the
NS run subroutine, using "uplevel 1" so that the context is correct.
You can of course include you own goo, in which case the default goo
will be skipped.

so unhappy with my current approach that I decided to drop that idea
for now and just specify the eid of the experiment to run.  Obviously,
it has to be an existing experiment in the same project, whose nsfile
is grabbed from the DB and shipped over to the inner boss.

	tb-set-security-level Green|Yellow|Orange:Red

Also add a template elabinelab.ns file.

Minor additions to support node mobility events:

	* lib/libtb/tbdefs.h, lib/libtb/tbdefs.c, sql/database-fill.sql:
	Add SETDEST as an event type and NODE as an object type.

	* tbsetup/ns2ir/node.tcl:
	Add location (X_, Y_, Z_) and orientation attributes for mobile
	nodes.

	* tbsetup/ns2ir/sim.tcl:
	Add a "setdest" event for node types that lets the user move a
	mobile node.

xmlconvert won't choke on it.

Add elab_in_elab boolean to experiments table. Add inner_elab_role
to virt_nodes table, which is one of boss,ops,node.

webfeedback to talk to the newer version of canaryd.  Add feedback
"estimate" stuff so that if we have no data (because of an overloaded
node) to work with, we can make some sort of "reasonable" guesstimate
on every iteration.

	set g1 [new EventGroup $ns]
	$g1 add  $link0 $link1
	$ns at 60.0 "$g1 down"

See the new advanced tutorial section on event groups for a better
example.

Changed tbreport to dump the event groups table when in summary mode.
At the same time, I changed tbreport to use the recently added
virt_lans:vnode and ip slots, decprecating virt_nodes:ips in one more
place. I also changed the web interface to always dump the event and
event group summaries.

The parser gets a new file (event.tcl), and the "at" method deals with
event group events by expanding them inline into individual events
sent to each member. For some agents, this is unavoidable; traffic
generators get the initial params in the event, so it is not possible
to send a single event to all members of the group. Same goes for
program objects, although program objects do default to the initial
command now, at least on new images.

Changed the event scheduler to load the event groups table. The
current operation is that the scheduler expands events sent to a
group, into a set of distinct events sent to each member of the
group. At some point we proably want to optimize this by telling the
agents (running on the nodes) what groups they are members of.

Other News: Added a "mustdelay" slot to the virt_lans table so the
parser can tell assign_wrapper that a link needs to be delayed, say if
there are events or if the link is red/gred. Previously,
assign_wrapper tried to figure this out by looking at the event list,
etc. I have removed that code; see database-migrate for instructions
on how to initialize this slot in existing experiments. assign_wrapper
is free to ignore or insert delays anyway, but having the parser do
this makes more sense.

I also made some "rename" changes to the parser wrt queues and lans
and links. Not really necessary, but I got sidetracked (for several
hours!) trying to understand that rename stuff a little better, and
now I do.

new directive for your NS file: tb-use-physnaming(1) which means that
if you have a line like this:

	set pc6 [$ns node]

and pc6 is an actual name of a physical node, then do an implicit
"fixnode" to pc6. In other words, pc6 is the name of the node in your
NS file (virtual topo) *and* will be fixed to the real pc6. Needless
to say, if pc6 is allocated when you go to swapin, you lose.
