Merge remote-tracking branch 'qatar/master'

* qatar/master: (29 commits)
  cabac: Move code only used within the CABAC test program into the test program.
  vp56: Drop unnecessary cabac.h #include.
  h264-test: Initialize AVCodecContext.av_class.
  build: Skip compiling network.h and rtsp.h if networking is not enabled.
  cosmetics: drop some pointless parentheses
  Disable annoying warning without changing behavior
  faq: Solutions for common problems with sample paths when running FATE.
  avcodec: attempt to clarify the CODEC_CAP_DELAY documentation
  avcodec: fix avcodec_encode_audio() documentation.
  FATE: xmv-demux test; exercise the XMV demuxer without decoding the perceptual codecs inside.
  vqf: recognize more metadata chunks
  FATE test: BMV demuxer and associated video and audio decoders.
  FATE: indeo4 video decoder test.
  FATE: update xxan-wc4 test to a sample with more code coverage.
  Change the recent h264_mp4toannexb bitstream filter test to output to an elementary stream rather than a program stream.
  g722enc: validate AVCodecContext.trellis
  g722enc: set frame_size, and also handle an odd number of input samples
  g722enc: split encoding into separate functions for trellis vs. no trellis
  mpegaudiodec: Use clearer pointer math
  tta: Fix returned error code at EOF
