[Xorg] Savage DRI DDX to xorg merge

[Alex Deucher]

I just finished the preliminary merge.  It seems to work ok in limited
testing.  for those interested the patch is here:

http://www.botchco.com/alex/xorg/savage-dri-to-xorg.diff

the code still needs the "develdri" #ifdefs added.  I'm not sure
exactly where those need to go off hand.  also the savage dri is still
only in mesa.
At this point this can probably wait until after the next release for merging.
