Add the ability to set the BIOS version, serial number, and service tag from
the nodecontrol page and command line util.  Must be admin.

a link cause the BW or Loss is out of range; post the messages back
through the event system so that it ends up in the log or on the web
page.

Oops - change length of varchar to 32 (was 64).

Add serial and service_tag columns to the database for tracking machines.

 * Add a "showclass" param to shownodes so that the
   node listing will include only nodes of the indicated class.
   Prepend "no-" to exclude nodes of a particular class.  So:
        showclass=pc,mote
   would show just pcs and motes.

 * Now the real reason I added the above: change the hwdown experiment
   node list to include "showclass=no-pcplabphys" by default so I don't have
   to flip through 600+ dead plab nodes.  Change the URL to "showclass=all"
   if you want to see plab nodes in hwdown.

addresses in the list, use real email addresses. Why? Well, cause I'm
a dope.  Oh, the real reason is that people cannot post to the lists
if we use their @emulab.net addresses cause we close the lists (to
avoid spammers). I did it this way originally cause it was easier;
there is a lot more bookkeeping to do if using real addresses, and I
never consider problem of not being able to post.

lists.  This (harmless) bug has been around a while; needed to move
the call to genelists up a level from setgroups to modgroups, since
that is where we have the information about what groups a user has
been deleted from, and so can tell genelists to regen those project
mailing lists.

for more then one user) as this messes up mailman. Besides, we will
eventually have to switch to email uids at some point, so they will
need to be unique anyway.

This seems to be necesary because of what I can only describe as a
bug in CatOS in which not ll ports in a trunk return the proper channel
grou number.

see experiments of other people in the NSDI project.

Added sitevar "general/open_showexplist" which when set to the name of
a project (NSDI), will allow users in that project to view all the
experiments that are swapped in by other members of the project, even
if the experiments are within another project.

Also quickly hacked showuser page to only show project/group listing
of overlapping projects, not all projects. This avoids some leakage.

support NSDI06 easily, we want to create a project called NSDI06, have
anyone who has an NSDI deadline join that project, and use that
membership to allow them to swapin experiments in their real projects.
So, new global_policies entry format:

	insert into global_policies
	     values ('membership', 'emulab-ops,testbed,NSDI06', 'eq', 0);

When this policy is inserted, only members of the comma separated list
of projects names can swap in *any* experiments.

Just remove the table entry to remove the retriction.

Also add names of machines to table of how-many-have-what-nics.

and nodes. I did this openoffice, but its a really simple picture, so
I will be happy to change when Mike decided to rearrange it all.

Change enable_endnodeshaping to linux_endnodeshaping and update sitevar
description to match reality.

is easier to check for linux nodes, and still have a hope it will patch
into older snapshots.

The placement of this code is whacky cause I needed a spot in
the file that has been sorta stable for the last year or two.

Remove the RHL90-specific delaysetup script.  It's now common, existing
only in the 'linux' subdir.
