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.

WMApro actually support 13-bits block sizes (potentially even up to 14),
and thus we should support that also. If we get block sizes beyond what
the decoder can handle (14 is possible depending on s->decode_flags),
error out instead of crashing.

Deprecate avcodec_decode_audio3().
Implement audio support in avcodec_default_get_buffer().
Implement the new audio decoder API in all audio decoders.

Also fix some undefined unsigned/signed conversions.

They are used in lavf.

use put_bits_count to get the buffer fill state instead of
num_saved_bits as num_saved_bits is sometimes reset when
frames are lost
(Ticket 495)

It's more readable and less prone to breakage.

Most of these variables are only used in av_dlog statements, some
are required but not used by other macros.

These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.
