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.
