Merge remote-tracking branch 'qatar/master'

* qatar/master:
  dv1394: Swap the min and max values of the 'standard' option
  rtpdec_vp8: Don't parse fields that aren't used
  lavc: add some AVPacket doxy.
  audiointerleave: deobfuscate a function call.
  rtpdec: factorize identical code used in several handlers
  a64: remove interleaved mode.
  doc: Point to the new location of the c99-to-c89 tool
  decode_audio3: initialize AVFrame
  ws-snd1: set channel layout
  wmavoice: set channel layout
  wmapro: use AVCodecContext.channels instead of keeping a private copy
  wma: do not keep private copies of some AVCodecContext fields
