  vf_hwupload/hwmap: Support setting a fixed pool size
  
  These filters do not directly know whether the API they are using will
  support dynamic frame pools, so this is somewhat tricky.  If the user
  sets extra_hw_frames, we assume that they are aware of the problem and
  set a fixed size based on that.  If not, most cases use dynamic sizing
  just like they did previously.  The hardware-reverse-mapping case for
  hwmap previously had a large fixed size (64) here, primarily as a hack
  for QSV use - this is removed and extra_hw_frames will need to be set
  for QSV to work since it requires fixed-size pools (as the other cases
  do, and which didn't work before).

• mov : move stsd finalization to an appropriate place

  mov: move stsd finalization to an appropriate place
  
  mov_finalize_stsd_codec() parses stream information from the ALAC extradata,
  so run it after the extradata processing is completed in mov_read_stsd().
  
  Fixes playback of 96kHz ALAC streams muxed by qaac or the reference alac encoder.
