bd4dceeff4 codecparsers: h264: complete set of NAL unit types.
Add missing NAL unit types. They are mostly related to alpha blending,
scalable video coding extensions (SVC, Annex.G), and multiview video
coding extensions (MVC, Annex.H).

af78b45979 h264parse: Fix multiple SEI messages in one SEI RBSP parsing.
An SEI RBSP could contains more than one SEI message as specified in
7.4.2.3.1.

This commit change the parser API: the gst_h264_parser_parse_sei()
function now create and fill a GArray containing GstH264SEIMessage.

529ece338f h264parser: Parse the cropping-rectangle separately.
Assign the un-cropped width/height to sps->width/sps->height
during sps header parsing. Added new fields to SPS header structure
to provide the crop-rectangle dimensions.

2c3eaf527b codecparsers: h264parse: don't use anonymous unions.
Anonymous union is an ISO C (2011) feature that is not exposed in
compilers strictly conforming to the previous standard.

5c9f790075 codecparsers: h264: record number of emulation prevention bytes in slice_header().
Some hardware video decode acceleration API (VA-API, DXVA) require
a bit count to the first macroblock, minus the number of emulation
prevention bytes. So, instead of having the consumer of the library
scan the slice_header() again, just record that number while parsing.

c92efe38e9 codecparsers: h264: fix ref_pic_list_modification()
The entries were not filled in linearly and the termination was not
recorded either. Now, the actual number of modifications is recorded
similarly to dec_ref_pic_marking(). i.e. an explicit counter instead
of storing the termination value in the array.

c4d987b6d3 codecparsers: Variant of _identify_nalu without checks
This is useful for cases where the caller *knows* that the provided
input contains a whole NALU and can therefore avoid:
* the expensive checks for the next start code (which won't be present)
* delaying the input parsing (since we would need the next incoming NALU
  in order for the parsing code to detect the next start code)
