another for all the geni RPC ports. Shot in the dark, we are out of ideas.

error in FreeBSD 10.

The pieces are:

 * A monitoring daemon (clientside/protogeni/shared-node-monitor), which
   runs in each Xen shared node dom0, and gathers node and interface
   statistics.  It communicates these over the event system with...

 * A listening daemon (event/monitoring/shared-node-listener), running
   on the local boss node, and inserts everything it hears into the
   MySQL database "monitoring".  This database is also used by...

 * A site-wide monitoring daemon (protogeni/scripts/mondbd), periodically
   polling the normal testbed database (nodes and interfaces tables) and
   copying snapshots of the important pieces into the monitoring database.

 * The monitoring database is also read by a WWW front end invoked as a
   WSGI process by Apache.  This front end is developed by the GPO and
   modified to work with ProtoGENI, and is maintained in an independent
   repository.

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).

different versions into v1/v2 subdirs, since I did not like the
naming.

Add new version of the ops httpd.conf file, again taken from Dave's
linux-port branch, and then whacked on.

Add utah versions of the boss/ops config files and a utah target.
These will probably get removed later when we switch over, but I do
not want to lose the work I did to merge in the local hacks.

running on a different port. This will solve the problem with ssl
renegotiation since at some point, we can turn that off (remove the
protogeni stuff) from the main https virtual server. This one runs on
a different port, and can in fact be a distinct IP addresse, but that
is not really necessary.

* The httpd.conf file I started with came from Dave's linux-port branch,
  and subsequently whacked for FreeBSD installation. Sorry for not using
  git to bring the base version in.

* Configure changes to determine what version of apache is installed, and
  modify behaviour in makefiles accordingly.

* Along with Apache 2.2 comes the latest version of PHP5, and that requires
  a bogus timezone directive in php.ini to prevent endless warnings. So I
  moved the entire php,ini install from ops/boss-install to here.

Note that I had to use the 8.2 ports tree to build this stuff, and it the
usual headache cause options and directives have changed.

Mostly this means a new package set emulab-*-3.1 and some corresponding
tweaks to the install scripts and elabinelab scripts.

PLEASE NOTE: a 7.3 install uses PHP5, Perl 5.10.1 and Python 2.6.

I thought I had done this before, but maybe I had just edited the
installed httpd.conf on boss in place. Oops!

that loads one of five different modules, based on the PATH_INFO.  The
modules do nothing but pull in the proper library; all of the xmlrpc
and authorization code is in one place now (the wrapper), instead of
being duplicated. Much cleaner, much safer.

An update to httpd.conf is required, and done with update script 7.

They are not in the top level GNUmakefile install, but if someone were to
manually install from their devtree, they would clobber the "master" versions.
This is because of the way that INSTALL_RCDIR and INSTALL_APACHE_CONFIG are
set in Makeconf.in.  They are not prefixed with ${prefix} since they can be
set directly via configure command line "--with" arguments.

it is ignored in directory context.

exp. vis. is an experimental feature.

vserver so that we avoid SSL renegotiation that is triggered when
doing it on a per-directory basis.

Also add ExportCertData so that the entire client certificate it
passed along in the ENV; we need those to get the URNs out of the
altname field.

pages from the /proj directory, without having to set the exec. bit on
/proj/PID.  Will also be used to handle authorization in the future.

Enabling and disabling the GENI AM API is a matter of adjusting the
Apache configuration to grant access to the /protogeni/xmlrpc/am
directory. This leaves the existing XMLRPC interfaces intact and
undisturbed.

Reign in a rogue ifdef in the makefile.
