project.

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.

breaking node->shark_lan links. Also cleaned up some hard-to-follow
code in the process of trying to understand how handle_ip works.

module file. Setup is now very short and simple, calling functions in
the library. The prepare script and the new rc.delta script load the
setuplib.pm module and use functions in there. Eventually, the library
should be common to all three OSs, but that was too much to deal with
today.
