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.

c51c08e0e7 avcodec: Use get_ue_golomb_long() when needed 
get_ue_golomb() cannot decode values larger than 8190 (the maximum
value that can be golomb encoded in 25 bits) and produces the error
"Invalid UE golomb code" if a larger value is encountered.  Use
get_ue_golomb_long() instead (which supports 63 bits, up to 4294967294)
when valid h264/hevc values can exceed 8190.

This updates decoding of the following values:   (maximum)
  first_mb_in_slice                                36863* for level 5.2
  abs_diff_pic_num_minus1                         131071
  difference_of_pic_nums_minus1                   131071
  idr_pic_id                                       65535
  recovery_frame_cnt                               65535
  frame_packing_arrangement_id                4294967294
  frame_packing_arrangement_repetition_period      16384
  display_orientation_repetition_period            16384

An alternative would be to modify get_ue_golomb() to handle encoded
values of up to 49 bits as was done for get_se_golomb() in a92816c.
In that case get_ue_golomb() could continue to be used for all of
these except frame_packing_arrangement_id.

2a72b1664d avcodec/h264: use avpriv_find_start_code() in h264_split() 
This also allows replacing several literal numbers by named constants
And it should be faster, the function is not speed relevant though as it is
generally only called a few times at the streams start.
