It does not help as an abstraction and adds dsputil dependencies.

This allows us to get rid of them on the next major bump. All of the
above are functionally irrelevant, and most of them are unused, except
the vp3 one, which is used wrongly in the bfin arch optimizations.

This is more correct and avoids breaking extended_data.

It's got_frame, not data size

It will be useful in the upcoming transition to refcounted AVFrames.

Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

Also remove one pointless zero initialization in rangecoder.c.

This fixes decoding of Bink files with non-multiple-of-16 width.

The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical
for most codecs, move Bink IDCT into separate context. Get rid of an additional
permutation table while at it since SIMD support for Bink IDCT is unlikely to
be implemented in foreseeable future.
Quantisation tables also have to change type to signed for proper
dequantisation of DCT coefficients.

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

This fixes visual glitches in Bink version 'b' files, as the quantization
tables were not being permuted.

Using doubles make the double -> int cast well defined for all the values
used, with the exception of when s[i]==1.0, which is special-cased.

instead of real width, this fixes decoding of some Bink files with odd width.
