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).

but never made use of. Moved to its own file (www/xmlrpc.php3.in)
and made to be more like the perl library I did a couple of months ago,
that presents an interface to an sslxmlrpc server, via the sslxmlrpc
client program operating in "raw" mode (takes raw xml on stdin, and
returns raw xml on stdout).

Added ELABINELAB code to nodetipacl.php3 so that you can click on
console icon on an inner emulab web page, and it will ask the outer
emulab sslxmlrpc server for the stuff it needs, and return that to the
user.

but simply entered into the DB record for the experiment until we know
what to do with them. Add to batchexp script arguments, since all that
stuff is done outside the web interface. Add a swapexp perl script to
swap an an experiment in/out form the command line. Add web links on
the Experiment Information page to do this from the web interface. A
bunch of locking changes. Previously expt_terminating in the
experiment record prevented multiple calls to terminate an experiment,
but now we have a more general locking problem with
start,swapin,swapout, and terminate, so change expt_terminating to
expt_locked (still a datetime field) and add locking to all of
startexp, swapexp, and endexp. Note that batch experiments cannot be
swapped yet because of locking issues still to be resolved. Minor
cleanup in tbreport to make email message look better.

perl script in the bin dir, so its available as a command line program
too. The link is available from the Begin Experiment page.
