* tmcd/ron: A new directory of client code, based on the freebsd
  client code, but scaled back to the bare minimum. Does only account
  and group file maintenance. I redid the account stuff so that only
  emulab accounts are operated on. Does not require a stub file, but
  instead keeps a couple of local dbm files recording what groups and
  accounts were added by Emulab. There is a ton of paranoia checking
  to make sure that local accounts are not touched.

  The update script that runs on the client node detaches so that the
  ssh from boss returns immediately. update can also be run from the
  node periodically and at boottime. The script is installed setuid
  root, but checks to make sure that *only* root or "emulabman" has
  invoked it.

* utils/sshremote: New file. For remote nodes, instead of using sshtb,
  use sshremote, which ssh's in as "emulabman", which needs to be a
  local non-root user, but with an authorized_keys file containing
  boss' public key.

* web interface changes: Allow user to specify his own public key in
  addition to the emulab key.

  Add option in showexp page to update accounts on nodes in the
  experiment. I was originally intending to do this from approveuser,
  but this was easier and faster. I will add an option to do it on the
  approveuser page later.

* libdb.pm: Add a TBIsNodeRemote() query to see if a node is in the
  local testbed or a pcRemote node. Currently, this test is hardwired
  to a check for class=pcRemote, but this will need to change to a
  node_types property at some point.

* node_update: Reorg so that there is a maximum number of children
  created. Previously, a child was forked for each node, but that
  could chew up too many processes, especially for remote nodes which
  might hang up. For the same reason, we need to "lock" the experiment
  so that it cannot be terminated while a node_update is in progress.
  Might be to relax that, but this was easy for now. Also add
  distinction between local and remote, since for remote we use
  sshremote insted of sshtb. Various cleanup stuff

* mkacct; When generating a new account, include user supplied pub key
  in the authorized keys file, in addition to the eumlab generated
  key. Both keys are stored in the DB in the users table. Anytime we
  update an account, get a fresh copy of the emulab pub key, in case
  user changes it.

but simply entered into the DB record for the experiment until we know
what to do with them. Add to batchexp script arguments, since all that
stuff is done outside the web interface. Add a swapexp perl script to
swap an an experiment in/out form the command line. Add web links on
the Experiment Information page to do this from the web interface. A
bunch of locking changes. Previously expt_terminating in the
experiment record prevented multiple calls to terminate an experiment,
but now we have a more general locking problem with
start,swapin,swapout, and terminate, so change expt_terminating to
expt_locked (still a datetime field) and add locking to all of
startexp, swapexp, and endexp. Note that batch experiments cannot be
swapped yet because of locking issues still to be resolved. Minor
cleanup in tbreport to make email message look better.

added terminate options to the experiment and batch display pages.

Add trust/approval status in user list in project page.

Also change grp_memb to proj_memb.

EIDs no longer concatenate the PID into the string, but instead there
are independent PID/EID fields to make experiments unique. Also, there
were changes to the tb* scripts.
