c737799900 h264parser: Add gst_h264_parser_identify_and_split_nalu_avc() method 
Equivalent to _split_nalu_hevc() method in h265parser. This method
will scan start-code prefix and split into individual NAL units
if start-code prefix is detected

890d59e97e av1parser: Fix array sizes in scalability structure 
Since the AV1 specification is not explicitly mentioning about
the array size bounds, array sizes in scalability structure
should be defined as possible maximum sizes that can have.

Also, this commit removes GST_AV1_MAX_SPATIAL_LAYERS define from
public header which is API break but the define is misleading
and this patch is introducing ABI break already

49f200cb54 h264parse: Improved AU boundary detection 
- AU boundary detection reviewed to follow more closely H.264 spec. and more
  specifically clauses 7.4.1.2.3 and 7.4.1.2.4.
- The gist of the changes is a look-a-head in then next AU required identify the
  last vcl-nal of current AU and firt vcl-nal of next AU (according to
  7.4.1.2.4) followed by the identification of the first nal of next AU
  (according to 7.4.1.2.3).
- A backlog of all nals of current AU and next AU up to the point where current
  AU can identified completed is kept.
- In NAL alignement mode vcl-nal are sent immediatly but the history is kept to
  allow AU boundary detection. Non-vcl-nal can be delayed up to the reception of
  the next vcl-nal to allow a correct AUD insertion.
- Based on this improved AU boudary detection we can avoid erronous AUD
  insertion, like the one highlighted by test
  test_parse_sliced_with_prefix_and_sei_nal_au.
- Add support for MVC AU boundary detection. (H.7.4.1.2.4)
- Explicitly report SVC not supported. We don't have the SVC NAL parsing
  required to identify boundary. (missing dependency_id and quality_id fields
  from SVC, see G.7.4.1.2.4)

dacb2a2b51 h264parser: Fix return value parsing short header

GST_H264_PARSER_NO_NAL_END. This tells the parser element to
gather more data. Previously, it would assume the NAL is corrupted
and would drop the data, potentially causing stream corruption.
