[PULL xserver] X Server support for Fence Sync

[James Jones]

This is the exact patch series (v4) sent out earlier plus a few of the 
cosmetic suggestions applied.  For the removal of assert and a couple other 
things, I'll need to think about it a bit and retest.  If you want to wait for 
those, I'll have them done in about 3 hours.  However, I'd rather do them as a 
follow-on bugfix.

The following changes since commit 311cad33155c64ed996418808727fc417168592e:

  Fix Xdmx and Xephyr build when DTrace support is enabled (2010-12-02 
16:56:30 -0800)
