Merge remote-tracking branch 'qatar/master'

* qatar/master:
  avconv: use default alignment for audio buffer
  avcodec: use align == 0 for default alignment in avcodec_fill_audio_frame()
  avutil: use align == 0 for default alignment in audio sample buffer functions
  avutil: allow NULL linesize in av_samples_fill_arrays() and av_samples_alloc()
  avconv: remove OutputStream.picref.
  avconv: only set SAR once on the decoded frame.
  avcodec: validate the channel layout vs. channel count for decoders
  audioconvert: make av_get_channel_layout accept composite names.
  avutil: add av_get_packed_sample_fmt() and av_get_planar_sample_fmt()
