Merge remote-tracking branch 'qatar/master'

* qatar/master:
  mpegvideo_enc: only allocate output packet when we know there will be output
  Add names for more channel layouts to the channel layout map.
  sunrast: Add a sample request for RMP_RAW colormap.
  avcodec: do not override pts or duration from the audio encoder
  Add prores regression test.
  Enable already existing rso regression test.
  Add regression test for "sox" format muxer/demuxer.
  Add dpx encoding regression test.
  swscale: K&R formatting cosmetics for PowerPC code (part I/II)
  img2: Use ff_guess_image2_codec(filename) shorthand where appropriate.
  Clarify licensing information about files borrowed from libjpeg.
  Mark mutable static data const where appropriate.
  avplay: fix -threads option
  dvbsubdec: avoid undefined signed left shift in RGBA macro
  mlpdec: use av_log_ask_for_sample()
  gif: K&R formatting cosmetics
  png: make .long_name more descriptive
  movdec: Adjust keyframe flagging in fragmented files
  rv34: change most "int stride" into "ptrdiff_t stride".
