This reverts commit 9ad3cd5b.

The misdetection on OS X should be fixed, we will only get
problem reports if auto-detection is enabled.

In 81f2549e, 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.

This reverts commit 60dbf2ef.

This is not needed anymore, Ticket 1694 has been fixed differently

This prevents various values from becoming stuck at NAN and
output to become silent

Add AVBuffer-based reference counting API to it.

This field is private and should not be present in a public struct. It
is only used in DXVA with mpegvideo-based decoders currently.

This will allow us to avoid copying the packets in many cases.

This breaks ABI.

These could be used for reference counting, or for keeping track of
decoding progress in references in multithreaded decoders.

Support is provided by gcc/msvc/suncc intrinsics, with a fallback using
pthread mutexes.

When parsing the Xing/Info tag, don't set the bit rate if it's an Info tag.

When parsing the stream, don't override the bit rate if it's already set,
otherwise calculate the mean bit rate from parsed frames. This way, the bit
rate will be set correctly both for CBR and VBR streams.
