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

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)
