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

It is already checked in avcodec_decode_audio3()

Uses 'buf' directly instead of a separate iterator variable 'in'.

Uses the native sample format for the codec instead of left-shifting all
samples by 8.

Make the code easier to read.
