replaced by the "images" table. New os_info table is added. New web
pages to add and delete OSIDs to/from the os_info table, for use in
the NS file. tb-create-os is gone. handle_os no longer operates on the
tbcmds file, and no longer writes anything into the ir file. Moved the
setting up of os state (nodes table) from os_setup to handle_os, where
it should be. os_load and sched_reload now take a single argument, the
name of the imageid from the images table.

Also copy bootwhat.h from my oskit tree and build from local copy.

something useful, although I doubt it.

interface options (but leave the documentation and web page running),
simply do this in mysql:

	insert into nologins (nologins) values(1);

To turn the interface back on:

	delete from nologins;

pages, and take out the "studmuffin" check in the main menu.

every now and then. Also change the way experiments are selected to
be configured. Instead of trying to start the same experiment over and
over every 15 seconds, use a select to pick out experiments that have
not been tried within the last 10 minutes. This will favor brand new
experiments the first time, but after that all failed experiments are
treated the same. The least recently attempted experiment over 10
minutes is selected next.

the batch daemon knows when configuraton failed cause there were not
enough nodes. The batch daemon uses this in an information manner
right now, but later we should kick out experiments that fail for any
reason other than lack of resources.

for sharks) Accomplishes this by doing expanding the 'interfaces->reserved'
join to include 'nodes' and 'node_types.' Checks to be sure that
interfaces.card != node_types.control_net before including a particular interface.

This makes variable dereferencing work as expected.  So:

        for {set i 1} {$i <= 8} {incr i} {
            set c($i) [$ns node]
            tb-set-node-cmdline $c($i) "BATCH=1 DST_NAME=$c($i)"
        }

will now expand $c($i) to correctly to c-$i.  Similarly:

set node1 [$ns node]
puts "First node is $node1"

will output:

First node is node1.

Caveat: It assumes that every node and lan will be stored in a
variable.  So doing something like:

$ns duplex-link [$ns node] [$ns node] 100Mb 150ms DroPTail

while in theory valid and sensible, won't work.

A clean rewrite of the parsing stuff is probably something I should do
soon.  It needs it to do all the variable munging correctly.

mere users. os_load and os_setup reworked to use node_reboot.

basic algorithm is this:

* Find requesting node's control interface from the db
* Make a list of subnets the node is on, excluding the subnet on the
  control interface
* Get a list of ALL interfaces of nodes in our experiment (excluding
  interfaces with no IP). Sort by node_id, then IP address to ensure
  symmetry of LINK= numbers. Link number gets incremented for each
  interface on the remote node. The first _direct_ link
  (ie. same-subnet) to another node gets an alias.

Simple, really.
