1. Support for "one-shot" PXE booting ala the one-shot osid. Switches to
   pxelinux to boot WinPE and then switch back after done. Painful now
   because we have to HUP dhcpd everytime we change the PXE path, but we
   may be able to fix this in the future by going all-pxelinux-all-the-time.

2. Added pxe_select, analogous to os_select, for changing the pxe_boot_path
   including the one time path.

3. Added the WIMRELOAD state machine to shepherd a node through the process.
   Still has some rough edges and may need refining.

By convention, if $debug is set we always declare the swapin successful.
We were not doing that in a few places.

expiration warnings.

Might not be in its final form yet.

This only affects cases where -a and -p are both being used and there is a node of a type not allowed in the specified project with subnodes.

but has not been tested for actual Emulab. A typical elabinelab NS
file would look like:
    
    source tb_compat.tcl
    set ns [new Simulator]
    
    tb-elab-in-elab 1
    tb-elabinelab-singlenet
    tb-elab-in-elab-topology opsvm
    tb-set-elabinelab-attribute CONFIG_WINDOWS 0
    
    namespace eval TBCOMPAT {
        set elabinelab_maxpcs 1
        set elabinelab_hardware("boss") pc3000
    }
    $ns run

you can do this in your NS file:

tb-set-node-loadlist $myboss FBSD73-S2,FBSDXX-FOO

Note that this does not replace tb-set-node-os(), cause that is a
little too special. So in practice, you would do:

tb-set-node-os $myboss FBSD73-STD
tb-set-node-loadlist $myboss FBSD73-S2,FBSDXX-FOO

USERNODE, shortcut to exec only, without the ssh.

(jail) on boss. A typical NS file might look like this, although note
that windows support is not finished yet. 

source tb_compat.tcl
set ns [new Simulator]

tb-elab-in-elab 1
tb-elabinelab-singlenet
tb-elab-in-elab-topology opsvm
tb-set-elabinelab-attribute CONFIG_WINDOWS 0

namespace eval TBCOMPAT {
    set elabinelab_maxpcs 1
    set elabinelab_hardware("boss") pc3000
}
$ns run

    
    OPSVM_ENABLE=0
    OPSVM_MOUNTPOINT=""

OPSVM_ENABLE=changeme
OPSVM_MOUNTPOINT=changeme

CreateVnodes().

worked in the "new" version.  (It continues to work fine in
os_setup (no new).  The new version is used primary by GENI related
and Utah projects.)

instead of two slashes, if I want a single slash in the DB.

2. Add a new inner_elab_role; boss+fs+router which makes boss the FSNODE
3. Add loadlist to both virt_node and nodes for plumbing multi image load
   through from the NS parser.

Part I of "Lessons learned from a 100K node experiment". nfree would
run for hours trying to free 100K virtual nodes due to a slow query in
Node::ReleaseSharedBandwidth(). Now it takes 5 minutes.

There were other lessons as well, but they fall in the category of
"rearranging deck chairs" since we are going to have to massively overhaul
lots of infrastructure to support O(100000+) node experiments on a regular
basis.

This script is intended for use with 'git filter-branch' - it takes
a directory, finds all files that have been moved into that directory
and where they came from, and produces a script that moves (in the
filesystem sense, not the git sense) them from their old locations
to their new ones.

Then, you give this script to 'git filter-branch --tree-filter', and
it will re-write all history so that it looks like the files were
always in their new locations.

Written specifically for the move of the clientside stuff into its
own directory, and then off into its own repository.
