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.

8487987b87 h264: Print user data SEI under normal debug verbosity 
Drop the need of setting -debug bugs since it's not a bug, and the
message is already under a AV_LOG_DEBUG log level. Instead only print
it when there is an actual string in it.

80ea661128 avcodec: h264: Extract decoder methods 
Extract two methods from decode_registered_user_data in order to improve
code readability. Also make the constant holding the allocation size a
64-bit unsigned integer so that the size comparison against INT_MAX makes
sense.
