* 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

Fixes Ticket875
Compared to patch 1 this fixes a bright line at the right side.

Add -show_frames option to ffprobe.

Partially based on the work of Thomas Kuehnel <kuehnelth@googlemail.com>
for SOCIS 2011.

The wicked idea of creating a special "packets_and_frames" container for
structured formats (JSON and XML) comes from Clément.

This fixes a segfault on startup.

Also remove a commented-out and completely unused variable.

rtsp.h relies on network.h and the latter conditionally defines fallback OS
structures that rely on configure tests, which are only run if networking
is enabled.

This fixes various problems with getting stream info. For example playback of the
file of Ticket88. Multithreaded find_stream_info should be reenabled
once it works correctly

the previous documentation indicated how many bytes are read from the input,
not how many samples are read.

The previous sample used for this test only contained type 0 frames.
Replace it with a sample that also features type 1 frames.

Change the recent h264_mp4toannexb bitstream filter test to output to an elementary stream rather than a program stream.
Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

The fate reference is updated because the previous test skipped a sample in
each encode() call due each input frame having an odd number of samples.

Simplify printing from the main() context, in case probe_file() is not
called, as required by the pending -show_version option.

Simplify pending changes, as the writer context will be used in the
main() routine.

Required by a pending change in ffprobe.
