44d16df413 h264_parser: eliminate H264SliceContext usage 
It is no longer needed for anything.

a6e27f7add h264: factor out parsing the reference count into a separate file 
This will allow decoupling the parser from the decoder.

e9f884416c h264: move reading direct_spatial_mv_pred out of ff_set_ref_count() 
It has nothing to do with the reference count and so does not belong in
this function.

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.
