stuff that we used to have for the Emulab/Protogeni trac wikis.
Not much code, but it was hard fought!

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).

deleted, they still remain in the user table with a status of
"archived", but since all the queries in the system now use uid_idx
instead of uid, it is safe to reuse a uid since they are no longer
ambiguous. 

The reason for not deleting users from the users table is so that the
stats records can refer to the original record (who was that person
named "mike"). This is very handy and worth the additional effort it
has taken.

There is no way to ressurect a user, but it would not be hard to add.

project membership are still not anonymous though.  New function
AnonSENDMAIL in libtestbed which will try to make sure there is no
trace of the current user in the mail sent.

For now, stop sending membership approval related email to the project
admin list since this will also go to testbed-approval.  There is also
some code to remove testbed-approval from the proj-admin list after
the acceptance email but this is disabled for now since some times people
reply to the approval email.
