[PATCH xf86-video-ati 0/3] Initial glamor and SI support.

[Michel Dänzer]

The main purpose of these changes is to allow using this driver on SI hardware
and playing with the (still quite limited) Gallium radeonsi driver in an X
environment.

Longer term, glamor might be interesting for older Radeons as well. Right now,
its main drawbacks are missing XVideo support (shouldn't be hard to add to
glamor), and occasionally quite annoying diagonal tearing.
