usage of the batch daemon on swapin.

an alpha prefix and a numeric suffix which sorts by the number.

Changed monitor to accept an optional argument specifying the ip-address or name of the stub. If this optional argument is not provided, the monitor looks it up in the mapping. Changed run-monitor-libnetmon.sh to provide this extra argument. Note that run-monitor.sh is now deprecated. Always use run-monitor-libnetmon.sh

Added a new command line options '-r' to represent
running on planetlab:

- If -r, it sets the connection_retry to 3, sets
  idle period to 60, and don't daemonize it.

Added 2 new programs:

1- elvindtest: a simple program to verify if a particular
    elvindserver is up or not

2- evproxyplab.cc: evproxy for planetlab nodes. It subscribes
   to the following events:
   host = node's ip addr
   objtype = EVPROXY
   objname = __$nodeid_proxy
   eventtype = UPDATE | CLEAR | RELOAD

   On UPDATE, it adds a new subscription to listen to an
   experiment conveyed by EXPT field of UPDATE message.

   On CLEAR, it removes the subscription for a experiment
   experiment conveyed by EXPT field of CLEAR message.

   On RELOAD, it removes all active experiment subscriptions.

   Also, while it comes up, it sends a RELAOD event to emulab's
   event-server to reload it with all existing experiments:

   host = node's ip addr
   objtype = EVPROXY
   objname = __$nodeid_proxy
   eventtype = RELOAD

* Added wrapper function: event_set_idle_period
* Updated event_register functions with a new paramaeter of
  retry count.
* Fixed memory leak bugs in event subscribe/async_subscribe

Added code to insert mappings into the plab_site_mapping table.

get, you simply run stubd with the '-s' (standalone) option.

event_async_unsubscribe functions.  The async versions are for use in
callbacks where calling the normal blocking versions will cause
unbounded recursion.

file a meaningful name.

command line to use.  The old builtin defaults of '/kernel.delay' and
'/kernel.jail' are still used if nothing is found in the table.

intervals of exactly QUANTA.

However, it's my view that having stubm and stubd seperate is a bad
idea, since one is basically a copy of the other. They should be
merged back together so we don't have to fix the same bugs in both
places.

Merged in changes from tblog-2-branch:

          Move parts of libtblog into libtblog_simple.  Libtblog simple
          provided the basic logging functions but doesn't touch anything.
          Moreover including libtblog_simple doesn't automatically start
          the logging subsystem.  It also doesn't have testbed dependencies
          which mean 1) it can be used in the core testbed libraries (such
          as libdb, libtestbed) without introducing a circular dependency
          and 2) can be used independently.

          Reworked DBFatal and DBWarn to use tblog.  It will still email
          testbed-ops, however.

          Make use of the "cause" field to determine the cause of the bug.
          In particular tblog_find_error will look at the value of this
          field and report the "cause".  In the future different actions
          can be taken based on the ultimate "cause" of the bug, such as if
          testbed-ops should be notified.

          Change format of Error Message reported by libtblog.  As per the
          email "Format or Error Messages" ro testbed-dev.

          Have libtblog use its own Database handle to avoid problems with
          locked tables.

          Also set DBCONN_MAXTRIES to 3 for most important queries.  For
          queries that are not important don't send mail on error.

testbed parser.  For example, in:

  set node [$ns node]

The "set" creates a variable named node, but the testbed parser also
renames the object to be "node".  Doing a similar rename is hard in
the real NS parser since we have to change any existing references to
the object.  Instead, we dynamically create a procedure with the name
that forwards methods to the actual object.

And so, the corrupting of my soul continues.

Some pelab/plab event system hacks.

	* event/lib/event.h, event/lib/event.c: Add event_subscribe_auth
	which lets you specify whether any authentication should be done
	for events received through this subscription.

	* event/sched/event-sched.c: Handle EVPROXY objects.  Add a
	separate subscription for EVPROXY UPDATE events for each plab
	pnode (which might be too many...).  Also, need to update the EXPT
	field for events received through a noauth subscription so the
	proxies can figure out which experiments are active.

	* lib/libtb/tbdefs.h, lib/libtb/tbdefs.c: Add UPDATE event defs.

	* xmlrpc/emulabserver.py.in: Inject __plab_setup and
	__plab_teardown timelines into the eventlist when an experiment
	has plab nodes.  The __plab_setup timeline sends EVPROXY UPDATE
	events to each physical node while the __plab_teardown sends
	EVPROXY CLEAR events.  The __plab_setup timeline is run when the
	scheduler starts up, the __plab_teardown isn't run automatically
	yet.

Reorg last tmcd checkin a bit and fix a potential problem.

Changes to support reporting back the port elvind bound to in the
management slice, and also sending this back to non-MS slivers.

delay osid so that they don't get a delay node that can't load their
OS.

Note, I can't do this when the user does not ask for a specific delay
OSID, since then the OSID is dependant on the node type.
