Fixed some warnings in assign_wrapper that were subsequently caught.

exitonwarn is a library that, when used in a script, causes it to exit 255
when warnings are sent.  It still shows all warnings, just does an ugly
perl hack to error on script termination.

until we get the backend in place to set port speeds.

to avoid a blizzard of reboots all at once. This might solve the
problem of sharks rebooting okay, but failing to become proper members
of the testbed. A good thing to do in any event, especially with
people trying to run 50 node experiments. The reason for 8 of course
is that I want to isolate each shelf (after sorting the list). I pause
15 seconds between each shelf, and 10 seconds between each batch of 8

unit number and return them in reference variables provided. Returns
0/1 exit status either way.

"skip" region so that you can have an unknown slice anyplace on the

1. 'tb-set-hardware ... shark' and 'tb-set-hardware ... dnard' are now
functionally identical.  Previously only the former worked but both passed
the parser.

2. Assign will now exit very quickly in the case that, for a given virtual
nodes, there are no physical nodes that could match in type.  This should
never happen as the parser and assign_wrapper have checks that usually
prevent this.  However, in the case of problems in the code (such as #1)
this'll make it easier to debug.  In addition, as we add more types of
nodes and our estimates becoming increasingly inaccurate cases where this
might occur could slip in.  All calling code treats this identically to an
'insufficient resources' failure.

plastic. Useful for when plastic reboots, although it needs to be
run from paper of course. We should probably set up some kind of
reboot utility for when plastic reboots, since when capture fires up,
the "acl" files are all in the wrong group/mode. On the other hand,
this shared file based permission scheme is going to end up changing
anyway soon, since it won't work when the serial lines are on other
machines. Will need a tip permserver at that point.

of pty/tty based (since they have several annoying problems
associated). Note that permission is granted via the use of an "acl"
file; /dev/tip/machine.acl, which must be set to the group of the
project the node is in, so the user can read out the process id number
and the random bits that are used by capture to grant permission to
use (tip sends the random bits across first thing). This handshake is
due to change to a request/challenge scheme as described by Dave in
email to the testbed list.

of the check, so caller can make appropriate decision.

Many changes and updates for handling new types. The db now has types like 'pc600', 'pc850', and 'dnard', and each type has a class like 'pc' or 'shark'. This updates scripts that use types to use classes where appropriate, and to handle the new types where there were hardcoded things that couldn't be eliminated right now.

In failure messages, make errors more obvious by showing logged output before showing the ns file they submitted. Now things like 'Insufficient Nodes' will appear within the first 15 lines of the message, where they are easy to see. This also matches the format of the successful configuration messages.

to tell it how to parse interswitch links from assign.

It still assumes a single VLAN domain.
