6ea220cbee h264_sei: Add namespace prefix to all SEI values 
This avoids confusion with equivalent H.265 SEI values when both are
being used at the same time.

5c2fb561d9 h264: add H264_ prefix to the NAL unit types 
This will prevent conflicts e.g. in code that deals with both h264 and
hevc.

f638b67e57 h264: move the parameter set definitions to a new header file 
The PS parsing code is independent from the decoder, so it makes more
sense for it to have its own separate header.

251cbb4400 h264: create a new header for common h264 definitions 
Move the NAL unit types into it. This will allow to stop including the
whole decoder-specific h264dec.h in some code that is unrelated to the
decoder and only needs some enum values.

3176217c60 h264: decouple h264_ps from the h264 decoder 
Make the SPS/PPS parsing independent of the H264Context, to allow
decoupling the parser from the decoder. The change is modelled after the
one done earlier for HEVC.

Move the dequant buffers to the PPS to avoid complex checks whether they
changed and an expensive copy for frame threads.

These codes can come before the PPS and results in incomplete extradata.

218d6844b3 h264dsp: Factorize code into a new function, h264_find_start_code_candidate 
This performs the start code search which was previously part of
h264_find_frame_end() - the most CPU intensive part of the function.

By itself, this results in a performance regression:
              Before          After
              Mean   StdDev   Mean   StdDev  Change
Overall time  2925.6 26.2     3068.5 31.7    -4.7%

but this can more than be made up for by platform-optimised
implementations of the function.

7a82022ee2 h264_parser: Initialize the h264dsp context in the parser as well 
Each AVStream struct for an H.264 elementary stream actually has two
copies of the H264DSPContext struct (and in fact all the other members
of H264Context as well):

((H264Context *) ((AVStream *)st)->codec->priv_data)->h264dsp
((H264Context *) ((AVStream *)st)->parser->priv_data)->h264dsp

but only the first of these was actually being initialised. This
prevented the addition of platform-specific implementations of
parser-related functions.
