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.

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.

h264: move [uv]linesize to the per-slice context
...
While it is a per-frame variable, it is only really used in the
low-level decoding code, so it is more efficient to store it in the
slice context.

h264: use a smaller struct for the ref lists
...
There is no need to store a whole H264Picture, with a full AVFrame
embedded in it. This should allow getting rid of the embedded AVFrame
later.

h264: move the scratch buffers into the per-slice context
...
Also change the method for allocating them. Instead of two possible
alloc calls from different places, just ensure they are allocated at the
start of each slice. This should be simpler and less bug-prone than the
previous method.

As far as I can tell the value can never go outside
the int16_t type.
And especially the cost of the initialization is
reduced quite a bit by making it smaller.
Overall decoding speedup not measurable though.
