[Libva] [PATCH v4 intel-driver 00/11] Add support for H.264 MVC decoding

[Gwenole Beauchesne]

Hi,

This patch series applies to the git master branch and brings in
support for H.264 MVC decoding with a minimal set of mandatory
patches.

The following series are combined for convenience:
- Fixes to H.264 Reference Frames handling:
  <http://lists.freedesktop.org/archives/libva/2014-May/002133.html>
- Fixes to the lifetime of VA surface buffer stores:
  <http://lists.freedesktop.org/archives/libva/2014-May/002138.html>
- Add support for for Picture ID Remapping on Haswell and newer:
  <http://lists.freedesktop.org/archives/libva/2014-June/002325.html>

New series tested on Ivybridge and Broadwell only. No regression
observed for H.264 AVC conformance (168/168). All conformance tests
for MVC Stereo High profiles and Multiview High profiles that could be
assimilated to MVC Stereo High profile on Ivybridge passed (15/15).

v1->v2: combined the first two series, improved commit logs
v2->v3: dropped refactoring patches from third series and combined it
  here, fixed submission location for MFD_AVC_PICID_STATE on Haswell
v3->v4: improved docs and commit logs, fixed frame store updates for
  pre-Haswell generations, merged in fix for colZeroFlag setting

I kept the previous patch structure but, ideally, we could merge
Patch11, Patch3 and an additional optimization PatchX + restoring
Patch2 to become bug compatible with the existing version in git. That
would have complexified the review however. :)

So, only Patch10 and Patch11 are new vs the older v3 patch series. The
series to be pushed will be re-shuffled in a more logical order.
