88a3b4da3c codecparser: vp9: move persistent fields from GstVp9FrameHdr to GstVp9Parser
The subsampling_x, subsampling_y, bit_depth, color_space and color_range
fileds are moved from GstVp9FrameHdr to the global GstVp9Parser structure.
These fields are only present in keyframe or intra-only frame, no need to
duplicate them for inter-frames. This is an ABI change.

5ebf1d477d mpegvideoparser: Handle non-hierarchical profiles again
This is a regression from since mpegvideoparser was switched to
use the codecparsing library.

The problem is that the high bit of the profile_and_level is used
to specify non-hierarchical profiles and levels. Unfortunately we
were discarding that information.

Expose that escape bit, and use it in the element

d054a6918c codecparser: h264: initialize parsing structures
Initialize to 0 these parse structures before filling them: GstH264SEIMessage,
GstH264NalUnit, GstH264PPS, GstH264SPS and GstH264SliceHdr.

When calling the functions which fill those structures, they may fail, leaving
unitialized those structures. This situation may lead to future problems, such
as a segmentation fault when freeing, for example.

This patch initializes to zero these structures, before filling them.

fcd42b7d77 codecparsers: h265: Fix the selection of Active Ref Pic Set
If short_term_ref_pic_set_sps_flag is FALSE, the ShortTermRefPicSet
structure is supposed to derive from slice header. Which means,
CurrRpsIdx is equal to num_short_term_ref_pic_sets. But the number
of refpicsets communicated via sps header is only num_short_term_ref_pic_sets - 1.
And we are using slice_header structure to reference the last entry, which is
ShortTermRefPicSet[num_short_term_ref_pic_sets].

fdac09d843 h264parse: Clear SPS info after processing.
The SPS struct might be filled out by a call to
gst_h264_parser_parse_subset_sps, which fills out
dynamically allocated data and requires a call
to gst_h264_sps_clear() to free it. Also make sure
to clear out any allocated SPS data when returning
an error.

8a6cc4ed27 codecparsers: h265: Fix the range of delta_chroma_log2_weight_denom
ChromaLog2WeightDenom = luma_log2_weight_denom + delta_chroma_log2_weight_denom

The value of ChromaLog2WeightDenom should be in the range of 0 to 7 and
the value luma_log2_weight_denom  should be also in the range of 0 to 7.
Which means , delta_chroma_log2_weight_denom can have values in the range
between -7 and 7.
