A closer inspection of the 'fedora' case that I had been using revealed
that a few changes needed to be made for the CentOS 6 environment.  This
is loosely based on the fedora15 case, but stripped down and cleaned up
some.

Not sure how I got on this side track, but it is done.

Also rearrange configure.in to produce unattended answer files based on
which Windows keys are present in the defs file.

Also add a couple of missing Cygwin packages.

other options.

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).

Ugh, I am not a big fan of how we manage new OSes, but I started it!

So we can configure clientside-only so that imagezip has NTFS support.

Against my better judgement, use configure to set some vars in clientside
scripts. I try to avoid this to keep our client images from becoming Utah
specific.

This is specifically for run_linktest.pl.in, which is installed on both
ops and nodes. I could fix it to not use configure vars on nodes, but that
would break its primary use on ops.

OTOH, I fixed elab_linktest.pl.in to not use configure variables, since
it only runs on nodes.

Mike, use the --follow argument to git log to traverse across the mv.

clientside/tmcc/linux/sethostname.dhclient.in needs this.

clientside requres it to be there. As noted in previous revision, the
full emulab build always includes the clientside subdir, but a
clientside build will not necessarily include the rest of Emulab.
