This prevents sample_rate/data_length from going negative, which
caused various crashes and undefined behaviour further down.

Also break some long lines, remove codec function placeholder comments

The unused code being removed is for encoding only and therefore is not needed
by the decoder.

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

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

using a floating-point calculation is not necessary.

Note that this will not work in most cases with avconv and avplay due to the
AVCODEC_MAX_AUDIO_FRAME_SIZE limit, but it will decode correctly if given a
large enough output buffer.

TTA does not support float at all, and format 2 is encrypted TTA.

init_get_bits() takes a number of bits and not a number of bytes as

It's more readable and less prone to breakage.

Many samples will fail because "Output buffer size is too small."

Many samples will fail because "Output buffer size is too small."

This is not documented (and possibly not originally intended),
but it's what the current reference decoder does.
