Merge remote-tracking branch 'qatar/master'

* qatar/master: (21 commits)
  fate: allow testing with libavfilter disabled
  x86: XOP/FMA4 CPU detection support
  ws_snd: misc cosmetic clean-ups
  ws_snd: remove the 2-bit ADPCM table and just subtract 2 instead.
  ws_snd: use memcpy() and memset() instead of loops
  ws_snd: use samples pointer for loop termination instead of a separate iterator variable.
  ws_snd: make sure number of channels is 1
  ws_snd: add some checks to prevent buffer overread or overwrite.
  ws_snd: decode to AV_SAMPLE_FMT_U8 instead of S16.
  flacdec: fix buffer size checking in get_metadata_size()
  rtp: Simplify ff_rtp_get_payload_type
  rtpenc: Add a payload type private option
  rtp: Correct ff_rtp_get_payload_type documentation
  avconv: replace all fprintf() by av_log().
  avconv: change av_log verbosity from ERROR to FATAL for fatal errors.
  cmdutils: replace fprintf() by av_log()
  avtools: parse loglevel before all the other options.
  oggdec: add support for Xiph's CELT codec
  sol: return error if av_get_packet() fails.
  cosmetics: reindent and pretty-print
  ...
