Retire xorg-printserver.

- Update X.org ports to 7.3.
- Mark XFree86-4 as DEPRECATED with EXPIRATION_DATE set to 2007-12-25.
I hope that nobody will be bored enough on Christmas to remove them on
that day.

- Welcome X.org 7.2 \o/.
- Set X11BASE to ${LOCALBASE} for recent ${OSVERSION}.

Upgrade to X.Org 6.9.0 release.
Remove separate mtree file for X_WINDOW_SYSTEM=XOrg case. Both X11
distributions now use the one from /etc/mtree again.

If port belongs to X11 distribution different than ${X_WINDOW_SYSTEM} one,
point to The X Window System and Virtual Consoles chapter of FAQ.

Add SHA256.

Install rc sript with ".sample" postfix so it does not get executed by
default.

During build, munge PATH so that imake's makedepend will get picked up instead
of devel/makedepend, which crashes.

Upgrade X.Org ports to 6.8.2.
Release notes are available at
http://www.x.org/X11R6.8.2/doc/RELNOTES.html

Thanks to kris and krion for running several cluster test builds,
maintainers of GNOME for prompt responses, portmgr for postponing ports
freeze for this update, testers on FreeBSD-X11@ list and others that I
might have mised here.

Also included:
- fix for ATI Mobility on Dell Inspiron 7500 (obtained from Marc Aurele La
  France; obtained and tested by julian)
- fix for kbd driver on Sparc64 (tested by Aaron Dudek, Michael G. Jung and
  Matthias Muthmann), which still appears to have problems with some
  keyboards - so
- fix for kbd driver on PC98 (reported and tested by NAKAJI Hiroyuki; PR
  ports/77217)
- fix for i810 on HP D530 (obtained from Egbert Eich; obtained and tested
  by Anders Nor Berle; PR ports/74757)

Update X.Org ports to 6.8.1, and the DRI port to use Mesa 6.2.  Because Mesa 6.2
DRI drivers are incompatible with the old libGL in XFree86, they have been
repocopied to graphics/xfree86-dri.  Also note that with this commit the html
manpages are going away, and with it the runtime dependency on perl for the
imake port.
