XQuartz transitioned to XCB a few releases ago, and we're fully committed to it.  I bless any Xlib code that you want to nuke in the transition to XCB!!

We may have some difficulty in the src/glx/apple code since AppleDRI and AppleWM are Xlib-only.  I'm hoping to eventually move away from these protocols, and I'll just deal with the fallout as it happens.  Please CC me on reviews with a branch I can merge to test the changes before they are merged into master.
