  Exit as soon as possible if no filtering will be done.
  
  Improves the checkasm --bench cycle count on a Snapdragon 820e:
  h264_h_loop_filter_luma_8bpp_c:      72.4 ->  72.5
  h264_h_loop_filter_luma_8bpp_neon:   97.1 ->  56.3
  h264_v_loop_filter_luma_8bpp_c:     174.0 -> 173.5
  h264_v_loop_filter_luma_8bpp_neon:   62.9 ->  60.9
  h264_h_loop_filter_chroma_8bpp_c:    30.2 ->  30.3
  h264_h_loop_filter_chroma_8bpp_neon: 51.6 ->  25.7
  h264_v_loop_filter_chroma_8bpp_c:    57.3 ->  57.3
  h264_v_loop_filter_chroma_8bpp_neon: 28.0 ->  24.0

  libdav1d: update API usage to the first stable release
  
  The color fields were moved to another struct, and a way to propagate
  timestamps and other input metadata was introduced, so the packet
  fifo can be removed.
  
  Add support for 12bit streams, an option to disable film grain, and
  read the profile from the sequence header referenced by the ouput
  picture instead of guessing based on output pix_fmt.
