radeon: initial preparation for kms patch.

This patch contains most of the changes to the EXA and texture video
accel code.

It adds a few bits of pixmap support but doesn't actually do anything
useful KMS yet.

Testing this should not have any regressions over what we have already,
biggest worries are r6xx, I've fixed a textured video one, but no idea
what other might lurk

It won't build against libdrm radeon yet either
