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).

This version was the one used at GEC 8.

is very conservative so far: URNs are accepted as input, but all output
and database formats are unchanged to preserve compatibility.  Those more
pervasive changes will have to be made gradually, once the rest of the
federation has been updated.

for settings the user might want to vary, and try to make the output
helpful.

but is useful for me to test authenticating with delegated credentials.

Lots of corner cases that I am ignoring and recovery from errors is
just as crude. See xmlrpc/client.py ...

program protogeni/xmlrpc/client.py ... it is much easier to get a
simple python client running on your desktop then a perl client. Only
package you need to install is M2Crypto, which is easy. Perl needs
about 10 packages installed to xmlrpc over ssl. Sheesh.
