[965] Convert the driver to dri_bufmgr interface and enable TTM.

This is currently believed to work but be a significant performance loss.
Performance recovery should be soon to follow.

The dri_bo_fake_disable_backing_store() call was added to allow backing store
disable like bufmgr_fake.c did, which is a significant performance win (though
it's missing the no-fence-subdata part).

This commit is a squash merge of the 965-ttm branch, which had some history
I wanted to avoid pulling due to noisiness and brokenness at many points
for git-bisecting.
