- fully qualified boss' hostname (boss.emulab.net) for WA nodes.

1) added -q to make healthd not report to console/syslog
2) Fully qualified boss' hostname (boss.emulab.net) - for WA nodes.

a vastly stripped down version of the netbed cdrom version, but which
also asks for a root password.

user does not have a real account (frozen, unapproved, webonly, etc).
Thats a error condition for addpubkey, since it gets called as user
"nobody" and only certain operations are allowed as nobody, and regen
is not one of them!

	weren't counting all the free ranges in some cases
	didn't track min/max correctly (duh!)

Add a magical icon for the Emulab pages. Shows up on the tab for tabbed browsers, and
in the bookmarks, etc.

The current image isn't that great, but it's something. When we've got time, we'll
make it a little better by not trying to fit so much of the logo in at once.

what we normally do in the main map (generate a name for the node and
a CNAME for the virt name. Skip if there is a jailip, since that is
going to be handled in the private vnodes map. This means that
widearea vnodes without their own IPs will continue to get map entries
as before, but local vnodes with their own IPs will get the special
treatment and no dup entries!

stand alone (no underlying phys interface) so that both ends of a
virtual link can be on the same node.

Change "startcmd" to return the uid of the swapper, not the creator,
as the UID to run the startup command.

Get creator/swapper uid in the initial query for the node, instead of
as separate queries later. Saves some queries ...

Remove old code.

Add progagents command to return the list of program object names, and
the UID to run those objects as (again, the swapper not the creator).
This allows the program-agent startup code on the node to be more
selective in its elvin subscription, as well as running the programs
as the proper UID.

Changes to jailconfig. If the node has its own IP in the nodes table
(jailip), return that as JAILIP in the configuration for mkjail.

tunnels, interfaces, routes, and delay links. Currently in the freebsd
subtree, it will move to the common directory at some point. When used
with either -i or -u, it will also run the rc files, either to install
(-i) or to uninstall (-u). I suppose a logical option would be a -r
option to reinit (uninstall, followed by install), and that would be
easy to add. Also takes a -j option to specify a vnodeid (jail), which
does all the same stuff, but just for the specified jail node (tmcd
changed to return vnode specific data). So, this script can be used to
set up the phys node, or any single virtual node on that phys node.

Changed delaysetup to take the same options (-i, -u, -j), and I call
delaysetup from ifsetup, passing the options along.
