This makes the vp3 decoder less dependent on dsputil, and will aid
in making it (eventually) dsputil-independent.

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.
