mp3/ac3 probe: search for PES headers to prevent probing MPEG-PS as MP3.
This fixes out of global array reads.
The alternative solutions of checking the index or modifying the VLC tables
to prevent the index going outside are each about 1-2 cpu cyclces slower
per coded 4x4 block.
The alternative of padding the global tables directly is more ugly and
moving them to the context should benefit cache locality.

vf_overlay: rewrite request/push logic.
The old implementation, upon receiving a frame on the main
input, would request an overlay frame if necessary. This could
generate an infinite recursion, off-by-one frame mismatch and
other harmful effects, especially it the split filter is present
upgraph.
The new implementation uses the linear approach: it uses two
buffer queues for frames received out of turn and forwards
request_frame calls to the input where a frame is necessary.

vp8: move block coeff arithcoder on stack.
This prevents gcc from assuming that contents of it may have changed
between calls to vp56_range_get_prob(), thus preventing countless (and
unnecessary) movs. Decoding of sintel trailer goes from (avg+SG) 9.796
+/- 0.003 to 9.635 +/- 0.010.
We support every defined value for channel layout, bitrate and sample depth.
All other values are not unsupported, but reserved.
Update comments to say "are used" instead of "are known or exist".
ffmpeg: disable autoinsertion for -async on the output side of the filtergraph.
This fixes the issue that since the last merge -async caused 2 aresample
filters to be inserted
users that generate funny timestamps in a filtergraph should probably
manually insert a aresample filter where they need it.

fate: fix md5sum replacement on some systems
On systems where the 'md5' command is used, there is a conflict
with the md5() shell function in fate-run.sh. Using the 'command'
keyword bypasses the shell function for correct behaviour.
the new test doesnt work on all platforms, thus disable it until a better solution is found.
the dca2 test remains and provides partial testing until this is resolved

fate: fix acodec/vsynth tests for make 3.81
GNU make 3.81 applies pattern rules in declaration order rather than
by stem length as in 3.82. This moves the more generic patterns above
the more specific ones such that they work with either make version.
Some of the vsynth patterns are also simplified a little.

Make av_get_codec_tag_string() show codec tag string characters in a more

Apart alphanumeric chars, only the characters ' ' and '.' are used
literally in codec tags, all the other characters represent numbers.

movenc: Fix muxing of Apple Quicktime chapters. v3
There is basic support for muxing chapter information into the
Apple Quicktime format already, but there are two errors which
prevent correct detection on the player side.
1) A special apple 'text' atom needs to be included inside the
gmhd atom.
2) The *different* 'text' atom inside the 'stsd' atom needs a
proper header.
With these changes, the chapters are now picked up by Apple
players and reported correctly by tools like mediainfo and mp4chaps.
v3 Update: The stub TextSampleEntry creation is moved to where the
chapter track is created so it's now specific to this track.
