* add www/p5-CGI package which is deprecated in CORE and will be removed
   in perl 5.22,
 * rename xerces-c2-devel port to xerces-c2 to avoid needing to fix our
   scripts that check for a particular package

Big changes a comin' to try to get us back on the supported path.

 * perl 5.14 -> 5.20
 * mysql 5.1 -> 5.5
 * php 5.4   -> 5.6
 * tcl 8.4   -> 8.6
 * number of vim patches up to 683.

Not everything tested yet, but getting there.

Specific changes:

 * New install/ports directory. New packages for FreeBSD 10.1 are version
   6.1. Cleaned up the ports' Makefiles getting rid of conditionals for
   all older versions. Also got rid of ports we don't use. Old ports tree
   is now install/oports.

 * Install script changes. Make sure /usr/bin/perl and /usr/local/bin/python
   links exist. Ports no longer make these but we use them in '#!'. Changes
   to mysql install and startup script--mysql has changed a LOT since we did
   the support in 4.x. Create syslog entry for named.log. Make sure php.conf
   loads the legacy "mysql" module rather than using "mysqli".

 * Elabinelab support. reflect new packages, remove all old packages
   (except perl) before installing new versions, install "extras" package,
   make sure sendmail cert get regenerated, make sure /usr/bin/perl link
   exists, make sure /usr/local/bin/python link exists.

 * Custom ports. otcl and xerces-c2 have both been removed from the ports
   tree as of Q2 2015. ipmitool-devel is a port for the latest version of
   ipmitool. The FreeBSD port is still a rev behind here. We need the
   newer version as it appears to make our SOL consoles more stable.

 * Random. Fixed prerender as neato output has changed again. Tweak to
   sslxmlrpc_server to reflect change in an underlying library. Tweak to
   db/libdb.py.in to turn on autocommit which matters now as mysql 5.5 will
   hang on a metadata lock otherwise. Remade eventsys perl/python stubs
   with SWIG 2.0. SWIG 1.3 did not produce working stubs for perl 5.20.

Specific un-changes:

 * Apache is still at 2.2. I lack the guts and skilz to upgrade to 2.4.

 * Xerces library is still at (now unsupported) 2.8. Assign will need
   changes before we can move to 3.x.

 * Python is still 2.7.

Thanks to Keith Sklower for all the work he did converting ports!

The biggest changes were related to 10.0's replacing gcc with clang
and the switch to a new package system. The former required various
fixes to Makefiles that hardwired "gcc" and also missing prototypes
in source files that clang is particularly obnoxious about.

There was also accomodating the normal evolution of the ports tree.
New variables were needed in many of the Makefiles for this. Hopefully,
all the changes I made are backward compatible, but I don't actually
care that much since I hope to never, ever have to remake those older
packages! A new emulab version of the m2crypto port was needed to
reflect that m2crypto is no longer installed as an .egg file.

Casualties:

  * Emulab assign. As of this commit, assign does not build with
    clang. It will build, but immediately core dumps if built with
    a gcc port (gcc46 below). THIS NEEDS TO BE FIXED!

  * Emulab nsverify. This requires building a pure ns-2.34, which
    is old and does not compile with clang. You will need to set
    NSVERIFY=0 in your defs file. I did this in defs-elabinelab
    (iff FBSD==10) but no where else right now.

  * Bind in the base distro. Bind is no longer part of FreeBSD
    (it has been replaced with something called "unbound"). So we
    install bind99 from a port and we make the /etc/namedb symlink
    to /usr/local/etc/namedb which is where it now lives.

  * Perl 5.12. It has been totally removed from the ports tree.
    We now install 5.14, the next-most obsolete version of Perl!

  * pkg_{add,delete,info}. As mentioned, the packages tools have
    changed. For the most part "pkg <cmd>" is the same as "pkg_<cmd>"
    but not always. This required considerable violence in the
    install/phases code. But it is actually cleaner now.

  * GCC in the base distro. I added installation of the gcc46 port
    to the boss and ops meta packages, just for old-times sake
    (we might wind up needing it, if still more stuff doesn't work
    with clang).

Tipserv port only includes libtelnet which is only needed for the icebox,
so this port is not "linked in" to the documentation yet and is not required
anywhere but on our PRObE cluster.

Added a couple of missing ports to "boss" and "extras".

It has been removed entirely from the FreeBSD ports tree and we still need
it because it has a dhclient which takes multiple interfaces on the command
line (the current version just takes one interface). We should move to the
new version, but I am not up to that yet...

Upgrade to perl 5.12 means no more "suidperl" (setuid perl scripts).
So we now have yet another little wrapper (security/runsuid.c) which
runs suid and whose sole function is to exec the perl script of the
same name in the /usr/testbed/suidbin directory. So a formerly setuid
perl script install now goes like:
  create /usr/testbed/sbin/mkproj as a symlink to /usr/testbed/libexec/runsuid
  install real mkproj perl script in /usr/testbed/suidbin/mkproj
When the setuid-wrapper is invoked under the name "mkproj" it execs
/usr/testbed/suidbin/mkproj. We could almost use sudo for this purpose
instead (see security/sudoers.in) but sudo loses one of the groups in
the group list.

/usr/include/utmp.h is gone in FreeBSD 9.0. In most places we nevered
needed it, but in the one case that did (tg source), it just used a
couple of the constants exposed (UT_*) and not the struct, so I just
hardwired values for the constants.

The usual tweakage to the install stuff to reflect yet another set of
packages!

Still a work in progress.

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.

its really a hugely stripped down Emulab boss install, using a very
short version of install/boss-install to get a few things into place.

I refactored a few things in both the protogeni code and the Emulab
code, and whacked a bunch of makefiles and configure stuff. The result
is that we only need to install about 10-12 files from the Emulab
code, plus the protogeni code. Quite manageable, if you don't mind
that it requires FreeBSD 6.X ... Still, I think it satisfies the
requirement that we have a packaged clearinghouse that can be run
standalone from a running Emulab site.

to get recreated correctly.  So have ports-install apply a patch (though
it doesn't automatically recreate the INDEX as that takes forever...)

This will stay until we get rid of the old hacky "Mysql" interface usage.

THIS HAS NOT BEEN TESTED!

* Add mailman to the install process. This includes the package
  install, all the setup needed in ops-install, and the little patches
  we apply locally.

  Note: Only under 6.0: no point in going backwards since its a pain
  in the ass to build these packages for the 4.10 image.

* Push more of the package install back down into the ops/boss install
  scripts. This improves testing within those scripts, and avoids
  duplication. There are some changes in rc.mkelab that will temp
  mount the package dir on /packages for the benefit of the scripts.

tagged from the 6.0 release. Also lots of changes to the install
scripts to handle inatlling boss/ops/fs on 5.4. All changes are
conditionalized so that things will continue to work on 4.10, but
hopefully we will move away from that before the year is out.

actually installed on the images, but this is a good place for it.
Same source configures and builds on Linux as is, so just need to copy
over the source dir to a linux machine and config/build/install.

If someone knows how to create an rpm out of it, that would be great!

Entailed new instructions for manual setup as well as integration into
elabinelab framework.  First, the manual path:

setup.txt, setup-boss.txt, setup-ops.txt and new setup-fs.txt:
    Updated to reflect potential for separate fs node.  The org here
    is a little dicey and could be confusing with ops+fs vs. ops and fs.
    Has not been field tested yet.

*/GNUmakefile.in: new fs-install target.

configure, configure.in, defs-*:
    Somewhat unrelated, make min uid/gid to use be a defs setting.
    Also add config of fs-install.in script.

boss-install.in, ops-install.in and new fs-install.in:
    Handle distinct fs node.  If you have one, fs-install is run before
    ops-install.  All scripts rely on the defs file settings of FSNODE
    and USERNODE to determine if the fs node is seperate.

utils/checkquota.in:
    Just return "ok" if quotas are not used (i.e., if defs file FS_WITH_QUOTA
    string is null.

install/ports/emulab-fs:
    Meta port for fs node specific stuff.  Also a patch for the samba port
    Makefile so it doesn't drag in CUPs, etc.  Note that the current samba
    port Makefile has this change, I am just backporting to our version.

Elabinelab specific changes:

elabinelab-withfs.ns:
    NS fragment used in conjunction with
	tb-elab-in-elab-topology "withfs"
    to setup inner-elab with fs node.

elabinelab.ns:
    The hard work on the boss side.  Recognize seperate-fs config and handle
    running of rc.mkelab on that node.  fs setup happens before ops setup.

rc.mkelab:
    The hard work on the client side.  Recognize FsNode setup as well as
    differentiate ops+fs from ops setup.

Related stuff either not part of the repo or checked in previously:
    emulab-fs package

The ports-install script neglects to copy the ulsshblahblah port into
the ports tree, causing mayhem and havoc at remote site.  Updated.

version of the graphics/p5-GD port. This one works with perl < 5.6,
which we need for the moment. This can go away someday when we migrate
to a newer version of perl.

We have a few more sources changes then they do, so we cannot just use it.

into the proper location.
