another ack IF at least N acks are outstanding.

 * allow for no server program to be run
 * allow for a program to be run on all nodes (including planet-*)
 * mods for the new improved dbmonitor

Also allow setting of use_magent=2 to indicate that it should start an
iperfd to listen for traffic on plab nodes rather than the stub.

This is in support of Jon's desire to have the stub not be a traffic
receiver.

Currently if the auto-magent.sh script is started up with the environment
variable MAGENT_NORECV set, it will use the magent option and also start
up an iperfd on what would have been the peer server port.

Added a utility which will take two netmond files, and a log file, and generate tri-colored xplots of them. This correlates offered load seen by the stub and the monitor, and the bandwidth figures sent by the stub to the monitor.

to talk to bgmon to accelerate data collection.  Also handle the 1.0
PLR rates that are recorded in the DB to indicate down links.

libnetmon will attempt to connect to the monitor before giving up.
It used to try once and give up (still the default behavior).  Set this
to N to try N times one second apart or 0 to try forever.

If you start your app automatically from the ns/template, then you can
set a value in the ns file with either:
	set opt(LIBNETMON_CONNECTTIMO) 10
for the "old school" ns file, or:
	$ns define-template-parameter LIBNETMON_CONNECTTIMO 10
in a template.  Note that this will only work if you fire your app via
the program agent, otherwise you won't get the environment variable.

graph. These were the latest Emulab numbers provided by Kirk.

middleman_values.txt contains the numbers of Planetlab.
synulab_values.txt contains the numbers of Emulab

blocksize for the synth app.

These are picked up by the monitor via the environment.

The values for these can be extracted from the environment so they can
be changed between Template runs.

Fixed a bug in how bufferFull was calculated (it was erroneously true most of the time). Changed LeastSquares to require both a buffer full and increasing delays to consider a measurement authoritative.

apps/protocols that use X cpu on PlanetLab can also add network artifacts.

sfmiddleman sits in the middle as a compute-intensive proxy.  sfsender
sends the middleman n "messages" each composed of m "blocks", and can
pause for t1 and t2 times at microsecond granularity after each block send
and msg send.  sfmiddleman reads blocks and does operations on them
(default is decrypt/encrypt, can also do only encrypt), then forwards them
to all connected receivers.  You guessed it, sfreceiver connects to
sfmiddleman and reads blocks and prints timestamps.  For each op on a
block, sfmiddleman notes the number of microseconds taken by the crypto
ops, and the timestamp when it/they finished, and prints those.

There is one known bug.  I'll fix it in the morning.  If there are others,
I'll get them then too.

template world:
	set no_plab to 1
	set use_dbmonitor to 1
	put enough nodes in the plabnodes list
	use start-run and stop-run to do it

An unexpected exit code will cause the __all_programs HALT event to
fail and cause "Stop Run" to fail.

that pumps up bgmon.  To use:

	set USE_DBMONITOR non-zero
	modify DBMONITOR_INTERVAL from the default 10 seconds if desired
	make sure there are enough nodes listed in PLABNODES

These things can either be modified in the template, or in the instantiation
params.
