0955752898 libs: decoder: h264: decode SVC base layer only
Drops non-base NALs when the base-only property is set to TRUE.
This modifies the behavior for MVC streams with base-only too: All the
non-base units are dropped before they are decoded instead of dropping
the non-base frames.

The relevant part from the H264 spec is:
> Decoders that conform to one or more of the profiles specified in
Annex A rather than the profiles specified in Annexes G or H shall
ignore (remove from the bitstream and discard) the contents of all NAL
units with nal_unit_type equal to 14, 15, or 20.

To eliminate side effects from the offending units:
- PPS's with a broken seq_parameter_set_id (referring to dropped subset
SPS's) are ignored.
- The NAL parsing is skipped and their flags are set to
GST_VAAPI_DECODER_UNIT_FLAG_SKIP.
- Prefix units are not stored in prev_pi. Otherwise, parse_slice() would
use them even if they are flagged to be skipped. Subset SPS's and slice
extension units are not stored there either.

fd7d38f7d2 libs: encoders: remove unused cast macros
They are only used inside the code, where another macro is defined.
Thus these exported macros have no use.

b942f9e17f libs: encoder: h264: handle deprecated enum
In VA-API 1.0 the enum VAEncPackedHeaderH264_SEI is deprecated, and
instead VAEncPackedHeaderRawData should be used.

This patch creates a compatibility symbol,
VA_ENC_PACKED_HEADER_H264_SEI, to expose the used enum according the
VA-API version.

e8148cea0d libs: macro to get a renamed value in VA-API 1.0
In VA-API 1.0 the union bits in VAEncMiscParameterBufferROI has
renamed one member from roi_value_is_qp_delat to
roi_value_is_qp_delta, which is the correct name.

In order to keep back compatibility a macro has added to access this
union member.

e42ec3ad3c libs: context: use attribs index instead pointers
Coverity scan bug:

Out-of-bounds write. This could cause an immediate crash or incorrect
computations.

Coverity basically found that it is possible to assign more than 4
attribs in the array.

In my opinion this was produced because code pattern used pointer
arithmetic, which is not readable nor maintainable.

This patch refactors config_create() to use an array index rather than
pointer arithmetic. Also a run-time check for index size was added.

Coverity scan bug:

Dereference after null check: Either the check against null is
unnecessary, or there may be a null pointer dereference.

While looking for hte lowest poc, according to rest of the code, the
picture in the dbp (decoded picture buffer) might be NULL, thus we
could check for a NULL picture before assigned as found.

Also, split a comma operator because it is considered as a bad
practice because it possible side effects.

Dereference after null check: Either the check against null is

In the original commit for fill_picture_gaps() (commit 5abd2b90) the
prev_picture could be NULL, that's why the code did a null check. But,
since commit 52adebe7, the previous reference frames are tracked, thus
there is no need to check null anymore.

and perform encoding with multi reference frames as the following:

1\ The num_ref_frames is being considered as the number of

2\ Encoder adds 1 reference frame more to the reference picture list1
internally if b-frame encoding.
3\ If num_ref_frames is bigger than the number of refrence frames
supported in the driver, it will be lowered.
