[Intel-gfx] [PATCH 00/13] Xv cleanup and preparatory revamp for drmmode overlay

Hi all,

This patch series has two goals:

- Clean up the code Xv so I can understand it. I've mostly changed overlay
  related code. But I've also put some of the newly introduced helpers in
  textured video to some use. Still, only tested on a 855GM because that's
  the only hw I have.
- Revamp the code to prepare for drmmode overlay support. Minus
  initialization and mode-switching, all overlay hw access goes now through
  the three ums_overlay_* functions. My next planned step is to put the
  functionality of these 3 functions into the kernel drm.

The complete series should work after every patch to ease regression fixing
(as I've said, only tested on a 855GM).

Comments (esp. concerning my planned Xorg/kernel drm split) and testing
feedback highly welcome.

Yours, Daniel
