[Libva] [PATCH 0/2] Fix and simplify REF_IDX_STATE

[Gwenole Beauchesne]

Hi,

The following patches factor out and fix REF_IDX_STATE construction.

1. Bit5 set to 1 normally represents a frame, not a picture ;
2. RefPicList0/1 size is controlled by num_ref_idx_l0/1_minus1 + 1. So, don't
   traverse the whole array that may not contain valid data.
3. Cope for cases where decoder represents frame with TOP|BOTTOM.

Tested on ILK, SNB, IVB with gstreamer-vaapi. I will push that if nobody finds
out a regression by the end of week.

Regards,
Gwenole.
