  av1dec: update hwaccel decode_params on AV1_OBU_SEQUENCE_HEADER
  
  Previously, the callback was only called on init. This makes it
  get called on every frame.
  
  We should switch to VK_KHR_video_maintenance2 and provide all params
  upfront, but almost nothing supports it yet.

  avcodec/qdm2: Use explicit overread checks instead of implicit ones
  
  If there were not enough data, checksum_size would be read
  as zero (due to the implicit checks of the bytestream2 API)
  and run into a "data block size invalid" error. Erroring out
  earlier via "not enough extradata" is better.

  avcodec/qdm2, vorbisdec: Use compile-time const max_depth in get_vlc2
  
  It makes no sense to try to be exact with max depth
  in get_vlc2(): It will mean that the compiler emits code
  for all three stages of parsing and runtime checks for
  whether max_depth is big enough to parse the next stage
  when a not yet complete code has been encountered.
