* The rest of the backend support for simplistic experiment duplication,
  either from an existing (current) experiment, or from a specific
  archive revision of a current or terminated experiment.

* Rework the swapmod code so that the archive is committed at the exact
  end of the swapout phase. This required adding (and moving) some code
  from swapexp to tbswap sine that is where the actual swapout/swapin
  happens during a swapmod

* Add a special directory called "archive" to the experiment
  directory, which is a place where users can store stuff they want
  saved away. This will eventually be a user defined set of
  directories, but this was good for getting the basic mechanism in
  place. Note that the when the contents of this directory are copied
  out for placement into the archive, it is an exact copy made with
  rsync.

* No longer "clean" the contents of the temporary store between
  commits of the archive. This was creating a lot of headaches, and
  was also causing the revision history to get messed up. The downside
  of this is that we have to be more careful to explicitly delete
  files that the user no longer uses. I have not solved all these
  issues yet, so in the meantime files will get left in the archive
  even if the user no longer references them.

This change displays the tags and pointers to the Archive matching
the experiment history and provides a "run" button to check out the
NS file from an earlier run and turn that into a new experiment. Still
very primitive.

If you specify an explicit firewall, you are implicitly assigned security
level 2 and you cannot explicitly specify the security level.  Likewise,
if you specify a security level, you cannot also specify a firewall.

The reason for this is that security level 1 (aka "Blue") now has a slightly
different meaning.  It is intended for protecting the inside from the outside
rather than visa-versa.  The only practical implication of this is that for
level 1, we don't do all the fancy power-off-boot-into-MFS-zapbootblock stuff
that we do for higher levels.

Anyway, I wanted to make sure that if you specify your own firewall, you
DO have to go through the full cleansing swapout since we can't trust a
firewall that the Average Joe sets up.

- unbounded record time
- stats dump (by stdout) with USR1 signal

Need to delete latter after ~2 weeks.

that got mangled in last rev.

Also ensure DHCP is enabled on all connected interfaces.  Otherwise tmcc will fail.

boots up before attempting to reboot/reload the firewalled nodes.  Previously,
we would just let them beat their collective heads against the wall, PXEing
over and over, waiting for the firewall to come up.

hardwiring to 6 minutes.  Not using it yet, but it is there for the future.

Got rid of some more shark code.

* When adjusting the latency on very low bandwidth links, lets use 98
  bytes for the number of bytes on the wire. Where did 82 come from?

* Attempt to deal with session routing failures. Reworked the test
  code to do multiple trials (when session routing is active) in the
  hopes that routes will stabilize soon after trying to actually use
  the routes. Currently trying a second trial, with a delay of 60
  seconds + (0.25 * numberofnodes). I have no experimental basis for
  this number!

and a few other tweaks.  Also bumped parallelism from 10 to 25 rsyncs
at a time.

Add pid/eid to subject line of virtual node failure notification message.

Add a bit of additional output info, and fix a little bug in rc.inplab

event groups.

GNUmakefile: install camwce script (turns on SCSI write-cache) in freebsd MFS
slicefix: allow default= and label= names to start with a digit

Um, yeah, update the interfaces and widearea_nodeinfo tables too when a plab
node's attributes change.  Duh..  DB fixed up.

actual counts.

and now also tbres!

("correctly" here meaning "don't go down in flames", not "we should never
save the state of vnodes", that will have to be revisited)

Slice renewal updated to work with new PLC API.  Emulab-created plab slices
are no longer in danger of falling out from under our users!

Added the ability to use an "exceptions" file.

Added the ability to avoid starting new experiments if an experiment
failed to swapout and the ability to avoiding swapping out an
experient on unexpected failures.
