xorg-fontserver moved from x11-servers to x11-fonts (xfs).

Approved by:    portmgr (erwin)

Remove the FreeBSD KEYWORD from all rc.d scripts where it appears.
We have not checked for this KEYWORD for a long time now, so this
is a complete noop, and thus no PORTREVISION bump. Removing it at
this point is mostly for pedantic reasons, and partly to avoid
perpetuating this anachronism by copy and paste to future scripts.

Replace ugly "@unexec rmdir %D... 2>/dev/null || true" with @dirrmtry

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.

Make rc script require ldconfig so font server starts properly on systems
that already include local/X11R6 scripts in rcorder.

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.

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)

- Set USE_RC_SUBR to fix the new rcNG startup script
- Bump PORTREVISION

Add rcNG startup script. [1]

Font cache is not build by default, which makes related lines in
default configure file wrong, which in turn causes xfs to error out
on startup with default file. Tweak generation of said file in a way
that would make proper configuration depending on existance of font
caching code, so that this patch can be sent upstream. [2]

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.

- Extend IGNORE message, point users to instructions how to switch
  from XFree86-4 to X.Org.

Approved by:    anholt (x11 hat)

- Add the X_WINDOW_SYSTEM={xorg,xfree86-4,xfree86-3} variable to bsd.port.mk,
  and make XFREE86_VERSION map to it.  XFREE86_VERSION is now deprecated.
- Make xorg the default X_WINDOW_SYSTEM on -current.
- Add several new X_*_PORT variables which point to various pieces of X11 based
  on the setting of X_WINDOW_SYSTEM, and make ports use them.
- Add information to CHANGES about how to handle the transition.
