Merge remote-tracking branch 'qatar/master'

* qatar/master:
  fft: init functions with INIT_XMM/YMM.
  pcmenc: set frame_size to 0.
  gsm demuxer: use generic seeking instead of a gsm-specific function.
  gsm demuxer: return packets with only 1 gsm block at a time.
  avcodec: add GSM parser
  doc: Replace ffmpeg references in avserver config file by avconv.
  doc: Fix names of av_log color environment variables.
  Fix a bunch of platform name and other typos.
  Add some missing changelog entries and release 0.8_beta2
  No longer build libpostproc by default
  wtv: fix memleaks during normal operation
  threads: add CODEC_CAP_AUTO_THREADS for libvpx and xavs
