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.

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

It's more readable and less prone to breakage.

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.

None of these symbols should be accessed directly, so declare them as
hidden.

These macros are redundant. All uses are replaced with the generic
DECLARE_ALIGNED macro instead.
