Note: the implementation could be more efficient, but at
the cost of more diff.

lavfi: add an audio buffer sink.
Adapted to call av_buffersink_get_frame_flags() instead of
accessing the frame directly.
The PUSH flags is necessary for efficient scheduling;
otherwise there is no feedback when adding frames to
closed paths.
The NO_CHECK_FORMAT is a small optimization that does
not cost much to implement.
The KEEP_REF flag maps to the add/write distinction in
the fork's API.
Allows, amongst other things, to override the size guessed
by the sub2video hack.
Note: the -s option could have more or less the same semantic,
but it receives a special treatment by the options system.
This helps lazy users who didn't read the part about boolean options, in
case they grep for "-nostats".
-stdin and -stats are the only booleans option enabled by default. This
is a partial fix for Trac ticket #2332, a complete overhaul of boolean
options documentation is probably overkill.
This makes the vp3 decoder less dependent on dsputil, and will aid
in making it (eventually) dsputil-independent.

* commit '6e7b50b4270116ded8b874d76cb7c5b1a0341827':
mpegvideo_enc: drop support for reusing the input motion vectors.
Conflicts:
libavcodec/motion_est.c

In 81f2549, output pixel format was changed from rgb24 to planar yuv,
but the initialization was left unchanged. As a result, the chroma
planes were left uninitalized. This was not noticed since the current
ff_get_video_buffer() seems to be initializing the buffer. This won't be
the case anymore after the Evil Plan.
This way, they can be shared between mpeg4qpel and h264qpel without
requiring either one to be compiled unconditionally.

Put a copy of the 8bit functions only in dsputil, where they are used
for some other things (e.g. mpeg4qpel, mspel, cavsqpel). We could perhaps
also try to share specifically the 8bit functions from h264qpel between
it and the others, but that will be slightly more complicated. H264qpel
already had these functions, so we can simply remove the duplicates.

struct buff_data contains a pointer to struct video_data, so passing the
file descriptor again is redundant.

In particular:
1) save errno before it (possibly) gets overwritten by other calls
2) do not forget to enqueue the buffer again in case of error

This makes them pass standalone compilation tests. Previously,
they included atomic.h which included themselves again, leading to
double definitions.

This prevents trying to do some subtitles conversion for each event when
the character encoding is not found. It now aborts early instead of
flooding stderr.
