If "-s <seed>" is not specified, a timeofday-dependent random
seed will be used.

In any case, when in verbose mode, the random seed used will be
printed out at the beginning of the run.

condition that was probably caused by unexpected parallelism.

One semantic change is that we used to block SIGTERM (but not SIGINT, which
also would quit) during read/write operations.  I don't do that anymore,
so if you kill capture, the log could lose some console output.

overrunning the compression subblock (chunk), which can happen if the
data is already compressed, and its right near the end of the block.
There is no recovery mechanism in place, and so muct be sure not to
end up with more compressed data than can fit.

give this stuff a major overhaul when we move to the model where we
have data on when each node was last "touched" or actively used. (Most
of these changes will still be relevant.)

1. Fix a bug in idlecheck that we didn't really thing much about. It
turns out that the WanSpread people have had a 17 node expt idle for
over three weeks, we didn't detect it because the nodes were running
ospf and generating lots of network traffic on the exptl. net. We now
ignore the exptl. network traffic as a source of activity if they have
automatic ospf routing happening. We also ignore nodes that have any
trafgen endpoints.

2. After the changes in idlecheck, I updated idle view to correctly
handle a new flag idlecheck outputs to let us know that an expt has
ospf running and may be falsely inactive because we ignored net
traffic. It will probably be very rare that an active expt that is
running ospf will have only network activity and no tty activity, but
it is a potential source of false positives. I also did some random
libifying. There were some hard coded references to emulab.net that I
fixed to properly use the variables from the defs file.

3. I also updated request_swapexp.php3. It now inlcudes in the email
message a blurb about automatic swapping, depending on whether or not
they're marked swappable. (If swappable, it says "This experiment is
marked as swappable, so it may be automatically swapped out by
Emulab.Net or its operational staff." and if unswappable, it says
"This experiment has not been marked swappable, so it will not be
automatically swapped out.") It also has a reference to the Node Usage
Policy and gives the URL. So we now give them fair warning about
potentially getting swapped out and what our policies are.

Fix flags passed to slothd. Before, -f meant send an immediate update (which wasn't the default behavior). The latest slothd updates (several weeks ago at least) changed the polarity of the flag. It still does the non-default thing, but now that makes it wait an hour before sending an update. So we remove -f so it does the right thing.

where tmcd was returning multiple aliases since there were multiple links
between nodes. Thats been a bug for long time, but its very rare to have
two links between the same two nodes, and so I never bothered to deal with
it. I have "fixed" it, but the fix is very unsatisfying since the choice it
makes is not consistent. For example, on distrib the ideal choice is to
create aliases for the lan links, but instead I get a mix; one alias is for
the duplex link to uav, another to the lan link to display. To make it
select a consistent set, it will take even more hackery in tmcd, and I am
not in the mood for it right now, given how rarely this happens. At least
the host file is now "correct."

Re-worked the snmpitGet functions slightly to make them more
convenient and to work around some ickiness in the SNMP library.

directory so that they can be viewed later after the operation is
complete. I've also cleaned up the mechanism for determining when
a log file is active (for the web spew) by using another slot in the
experiments table, and added some libdb routines to manage that slot.
At present just the last (or latest) log can be viewed after the fact,
but we can change that later if think its really necessary. At the
same time, make it possible for admin types to view the log files for
other peoples expierments; spew is setuid, but flips back after
opening the file (does usual checks too). I've also incorporated the
log changes into the batch daemon, so you can view the last batch log
too, although I have not tested that yet!
