Merge remote-tracking branch 'qatar/master'

* qatar/master:
  rtp: factorize  dynamic payload type fallback
  flvdec: Ignore the index if it's from a creator known to be different
  cmdutils: move grow_array out of #if CONFIG_AVFILTER
  avconv: actually set InputFile.rate_emu
  ratecontrol: update last_qscale_for sooner
  Fix unnecessary shift with 9/10bit vertical scaling
  prores: mark prores as intra-only in libavformat/utils.c:is_intra_only()
  prores: return more meaningful error values
  prores: improve error message wording
  prores: cosmetics: prettyprinting, drop useless parentheses
  prores: lowercase AVCodec name entry

Conflicts:
	cmdutils.c
	libavcodec/proresdec_lgpl.c
	tests/ref/lavfi/pixfmts_scale
