  fftools/ffmpeg_dec: Always receive frames from decoder
  
  Up until now if avcodec_send_packet() returned an error,
  no attempt to receive a frame from the decoder would be made.
  Instead the decoder was presumed to be drained, so that more
  packets could be sent to it. Yet this need not be so:
  It can happen that a packet would decode to multiple frames
  and that decoding the first of these (the one that is decoded
  during the avcodec_send_packet() call) returns an error,
  in which case the decoder is not yet ready to receive more
  input as the remaining parts of the packet have not been decoded
  yet. In this case, an AERROR_BUG is triggered.
  
  This happens in ticket #11553 with VP9 (which uses a BSF
  to split VP9 superframes and is therefore affected by this).
  
  Fix this by always calling avcodec_receive_frame() unless
  xerror is set.

  avcodec/apv_decode: build the lut table only once
  
  No reason to build the exact same table once per decoding thread.

  cbs_apv: Check tile component sizes
  
  It was possible for the buffer pointers for the last tile to go over the
  end of the unit buffer leading to a read overflow during decode of the
  macroblock layer.  Check all tile component sizes to prevent this case
  and also catch related tile size mismatch errors earlier.
