Merge remote-tracking branch 'qatar/master'

* qatar/master:
  Revert "v210enc: use FFALIGN()"
  doxygen: Do not include license boilerplates in Doxygen comment blocks.
  avplay: reset decoder flush state when seeking
  ape: skip packets with invalid size
  ape: calculate final packet size instead of guessing
  ape: stop reading after the last frame has been read
  ape: return AVERROR_EOF instead of AVERROR(EIO) when demuxing is finished
  ape: return error if seeking to the current packet fails in ape_read_packet()
  avcodec: Clarify AVFrame member documentation.
  v210dec: check for coded_frame allocation failure
  v210enc: use stride as it is already calculated
  v210enc: use FFALIGN()
  v210enc: return proper AVERROR codes instead of -1
  v210enc: do not set coded_frame->key_frame
  v210enc: check for coded_frame allocation failure
  drawtext: add 'fix_bounds' option on coords fixing
  drawtext: fix text_{w, h} expression vars
  drawtext: add missing braces around an if() block.
