Remove XAA

Commit 0c6987df in June 2008 disabled XAA offscreen pixmaps per default,
as they were broken, leaving XAA only able to accelerate operations
directly on the screen pixmap and nowhere else, eliminating acceleration
for basically every modern toolkit, and any composited environment.

So, it hasn't worked for over four years.  No-one's even come close to
fixing it.

RIP.
