Merge remote-tracking branch 'qatar/master'

* qatar/master:
  libavutil: add utility functions to simplify allocation of audio buffers.
  libavutil: add planar sample formats and av_sample_fmt_is_planar()
  avconv: fix segfault at EOF with delayed pictures
  pcmdec: remove unneeded resetting of samples pointer
  avconv: remove a now unused parameter from output_packet().
  avconv: formatting fixes in output_packet()
  avconv: declare some variables in blocks where they are used
  avconv: use the same behavior when decoding audio/video/subs
  bethsoftvideo: return proper consumed size for palette packets.
  cdg: skip packets that don't contain a cdg command.
  crcenc: add flags
  avconv: use vsync 0 for AVFMT_NOTIMESTAMPS formats.
  tiffenc: add a private option for selecting compression algorithm
  md5enc: add flags
  ARM: remove needless .text/.align directives
