  avpacket: Initialize the allocated padding area in side data
  
  This makes sure that consumers of the side data actually can
  rely on the padding as intended, without having the callers of
  av_packet_new_side_data to explicitly zero initialize it.

  lavc: Add per-thread surfaces in get_hw_frame_parameters()
  
  This number is definitely required when frame threading is enabled, so
  add it here rather than forcing all users to handle it themselves.
  
  DXVA2 contained this addition in specific code as well (therefore being
  added twice in the internal case) - just remove it from there.

  lavc: Add support for increasing hardware frame pool sizes
  
  AVCodecContext.extra_hw_frames is added to the size of hardware frame
  pools created by libavcodec for APIs which require fixed-size pools.
  This allows the user to keep references to a greater number of frames
  after decode, which may be necessary for some use-cases.
  
  It is also added to the initial_pool_size value returned by
  avcodec_get_hw_frames_parameters() if a fixed-size pool is required.
