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.

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.

auth_mysql module (which is installed under different names depending on the
version).

This could have been done with configure or in boss-install.  I didn't do
the former because configure might get run before apache is installed.  I
didn't do the latter because you would have to remember to re-run configure
if you updated your mod_auth_mysql port.

browser). This came up in elabinelab cause WWWHOST (www.myemulab.x.y.z) is
not an exported (from outer emulab) CNAME for the bossnode, so I have to
set WWWHOST equal to BOSSNODE, which causes the browser to complain.

Some notes:

 1) Public user web directories are now disabled
    - links from above the DocumentRoot to user devel trees must now be used.

 2) Internal access exceptions to production and devel directories are specified
    for the testbed root dir, and inherited by upper directories.
    - Simplifies configuration complextity

 3) External access to system (e.g., / /usr /var, etc) are disallowed now
    - Previously, symlinks could allow access to system directories.
    - Individual exceptions must be introducted when access to a specific
      directory is required.

httpd.conf, so callinging it apache.conf and symlinking it is kinda
silly.

INSTALL_APACHE_CONF in some places and INSTALL_APACHE_CONFIG in
others. Oops.
