Added debugging information so that it is more clear what port the control server is using on the stub.

think the problem is that the archive is forked for a template
instance, but not committed before the first savepoint. This screws up
the archive cause the datastore directory has not been copied in yet,
and subversion pukes.

kludgy code in template_exprun that tries to ignore dead nodes during
start and stop run.

Rolled the AverageThroughputSensor into a special case of LeastSquaresThroughput. It still uses the same command line arguments/constants.

Bump plab rootball version.

Create event sequences to do the equiv. of start- and stop-experiment.
Rather than using those scripts, you now can use start-run and stop-run
which are just wrappers around tevc to trigger the sequences.

This checking is backward compatible in the sense that you can continue to
use start- and stop-experiment and should never notice a thing.

The new event model doesn't support a couple of things that the old script
based execution did, most notably, you cannot change command line arguments.
It does support real vs. fake runs.

script sticks around so the program agent has something to kill!

will not timeout in the dispatch routine.  It apparently will stay
in recvfrom() til it gets a packet.  This caused stop/snapshot events
(as well as "kill -TERM") to not do anything.

So we blast all the pthreads out of recvfrom with a signal after setting
the flag to force them to return from dispatch (pcap_breakloop).

PlanetLab node's load.

Added a new sensor which averages packets over a particular period of time rather than a particular number of acks. This provides a proof of concept of coarse-grained measurements reflecting changes in bandwidth. Increased the number of samples that LeastSquaresThroughput uses as a quick way to use coarse-grained measurements easily.

getting deleted.

* Copy template datastore to instance "datastore" directory, instead of
  "template_datastore" ... avoid mass confusion.

* Change xxx:// mappping from template datastore to the instance datastore.

has two problems:

 * not all LANs might be shaped so there may not be a delay-agent running
   to receive and acknowledge the RESET event, leading to a hang

 * we might wind up resetting a delay node more than once (once for each
   lan it is responsible for); probably not harmful, but might lead to
   again not sending a completion event and a hang.

As long as I can reset the one LAN I care about, or rather all its involved
delay nodes, I should be fine.

has been retransmitted. Thus, getIsRetransmitted() now works for not
only sends, but ACKs too.

If we were unable to find any of the packets that an ACK supposedly is
ACKing, then declare the ACK invalid.

There is still a know problem with PacketSensor - it gets 'range starts
in unknown packet' error more often than it should. That's next on the
list to fix.

function in an int.

DelaySensor no longer uses retransmitted packets to calculate delays.
This is mandated by RFC 2988.

Add more debugging output when we detect a bogus (<0) delay.

from libpcap (this is detected by the packet timestamps decreasing
instead of increasing.)

millsecond, giving us a 0 period. Defer byutes from such packets
until the next non-zero period so that we can get a non-zero period.

Now named by "E${exptidx" which sorta sucks but not much to do.

 * get rid of excess precision on bw/delay print
 * don't complain about missing plr

make it through to the monitor - they tend to wedge the experiment.

run simultaneously on the same planetlab node.

Confine tcpdump on the planetlab nodes to just the stub's traffic, so
we don't have to worry about nameserver traffic, ssh traffic, etc.

Make use_magent the defauly.

the port-setting options to fail.

Also removed an old debugging output that is no longer needed.

getting set by start-experiment has been solved.
