Don't need it after figuring out imagezip

Snapshots are done a little differently then openvz of course, since
there are potentially multiple disk partitions and a kernel. The basic
operation is:

1. Fire off reboot_prepare from boss. Changes to reboot_prepare result
   in the guest "halting" insted of rebooting.

2. Fire off the create-image client script, which will take imagezips
   of all of the disks (except the swap partition), and grab a copy of
   the kernel. A new xm.conf file is written, and then the directory
   is first tar'ed and then we imagezip that bundle for upload.

3. When booting a guest, we now look for guest images that are
   packaged in this way, although we still support the older method
   for backwards compatability. All of the disks are restored, and a
   new xm.conf created that points to the new kernel.

This commit is intended to makes the license status of Emulab and
ProtoGENI source files more clear.  It replaces license symbols like
"EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
blocks that contain actual license statements.

This change was driven by the fact that today, most people acquire and
track Emulab and ProtoGENI sources via git.

Before the Emulab source code was kept in git, the Flux Research Group
at the University of Utah would roll distributions by making tar
files.  As part of that process, the Flux Group would replace the
license symbols in the source files with actual license statements.

When the Flux Group moved to git, people outside of the group started
to see the source files with the "unexpanded" symbols.  This meant
that people acquired source files without actual license statements in
them.  All the relevant files had Utah *copyright* statements in them,
but without the expanded *license* statements, the licensing status of
the source files was unclear.

This commit is intended to clear up that confusion.

Most Utah-copyrighted files in the Emulab source tree are distributed
under the terms of the Affero GNU General Public License, version 3
(AGPLv3).

Most Utah-copyrighted files related to ProtoGENI are distributed under
the terms of the GENI Public License, which is a BSD-like open-source
license.

Some Utah-copyrighted files in the Emulab source tree are distributed
under the terms of the GNU Lesser General Public License, version 2.1
(LGPL).

Add the additional interfaces for boss.

can move them elsewhere.

	capturevm.pl pcvmxxx-yy boss

will create a directory called boss and take imagezips of all the lvms
into that directory. A slightly modified xen config is written to the
directory. The XEN VM should not be running of course, and the easiest
way to stop it (without losing the disks) is:

	/usr/local/etc/emulab/vnodesetup -jh pcvmxxx-yy

Copy the directory someplace, and then run:

	restorevm.pl boss /path/to/above/stuff

which create new LVMs and then imageunzip the contents into them. A
slightly modified xen config file is then written to /var/tmp, which
can started with "xm create /var/tmp/boss.conf".

No rocket science here, but this was the easiest way to get all the
disks we create for XEN elabinelab, and since they can pretty big, we
want to use imagezip.
