Symlink /opt to /local/pid/eid/vnodeid so that its easier to install
per-jail software.

generation code

Also a couple perf hacks:

* Local vnodes can start with the password/group file from the
  physnode, since locally they will be the same anyway. This avoids a
  blizzard of accounts requests at startup, which is by far the
  biggest chunk of data returned (well, except for host tables).

* To help serialize boot startup, vnodesetup now waits for the jail to
  finish starting up before it exits. It does this via a "goofy"
  mechanism I will not bother to describe.

course; its an optional argument.

Add group stuff; we get a group (csh, tsch) and a routine maps that
into a valid path to use in the pw commands.

like we set hostnames of local nodes (v0.wa-jail-link.testbed.emulab.net).
Also build a proper /etc/hosts file just like local nodes inside the
jail. Minor change to dohostnames(); do not munge /etc/hosts in place!
Generate a new copy and then atomically move into place. Phew, this
was a close one! Mike has me really worried about race conditions now
that I screwed the pooch in the frisbee client.

Add new crontab file install to run a stub crontab inside jails;
basically, runs the atq and the newsyslog stuff. Other stuff is
turned off including periodic.

totally forgot about (vnconfig does not return error status when a vn
device is busy). This was casuing the crashes.
Add a local only kludge to NFS mount /user and /proj into the jails. I
hate this. Should be using SFS, but without an agent thats not really
possible.
Add sshdport config setup from jailconfig. Look for that in the jail
config file and pass to jail.

percent, and optimize for space. Prelude to creating smaller jails
on local nodes, as soon as I can get SFS running inside a jail the way
I want it (in which case users will have access to their project and
home dirs on the file server).

Add Mike's IPADDR change, with slight modification. tmcd will specify
a list of ip addresses as a comma separated list, which are converted
to -i options to pass to jail. Kernel will restrict bind to these IPs.

rc.conf: Remove fixed -p argument. Now set by mkjail.
rc.local,jailctl: Update for client side path reorg and cleanup.
jaildog.pl,mkjail.pl: Numerous fixes for jailed nodes.

well (requires new libsetup.pm to be installed too). Still a work in
progress.
