Approved by:    krion@
PR:             ports/88711 (related)

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.

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.
