In preparation of the update of glib remove the -reference ports

Those ports mainly concern old Gnome2 libraries, the behaviour of this infra
is not compatible with the meson build system (being used in newer version)
the documentation is provided otherwise in the other version

x11-fonts/fontconfig: update to 2.13.92

Fontconfig 2.13.1 generated .uuid files in the fonts directory which where
not properly registered to the packages. To clean them up, please execute the
following command:

        find %%LOCALBASE%%/share/fonts -type f -name .uuid -delete

By switching to this RC, the dependency on libuuid can be droped again, and the
issue of registering uuid is moot.

Presenting GNOME 2.28.1 for FreeBSD.  The official release notes for this
release can be found at http://library.gnome.org/misc/release-notes/2.28/ .
Officially, this is mostly a polishing release in preparation for GNOME 3.0
due in about a year.

On the FreeBSD front, though, a lot went into this release.  Major thanks
goes to kwm and avl who did a lot of the porting work for this release.
In particular, kwm brought in Evolution MAPI support for better Microsoft
Exchange integration.  Avl made sure that the new gobject introspection
repository ports were nicely compartmentalized so that large dependencies
aren't brought in wholesale.

But, every GNOME team member (ahze, avl, bland, kwm, mezz, and myself)
contributed to this release.

Fix the plist, bump the PORTREVISION.

Reported by:    pointyhat via pav

Fix plist

- Welcome X.org 7.2 \o/.
- Set X11BASE to ${LOCALBASE} for recent ${OSVERSION}.
- Bump PORTREVISION for ports intalling files in ${X11BASE}.

- Fix plist

Reported by:    pointyhat

- Add header in these *-reference ports.
- Fix a few of pkg-descr by chase the rename.
- Move all PORTREVISION and PORTEPOCH to top with ?=.
- Put USE_X_PREFIX back in, but under REFERENCE_PORT, and remove PREFIX? and
  USE_XLIB. This fix ports to use the correct mtree when you change the prefix,
  for example:

        Incorrect: (Without USE_X_PREFIX)
        ================================
        # cd /usr/ports/x11-toolkits/gtk20
        # make -V MTREE_FILE
        /etc/mtree/BSD.x11-4.dist
        # make PREFIX=/tmp/foo -V MTREE_FILE
        /etc/mtree/BSD.local.dist <-- Here...
        ================================

- Add pkg-descr
