Avoids an infinite loop in the calling programs with decoder not
consuming any input and not returning output.

This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3)
independent of dsputil.

Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.

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

channels, sample_rate, bit_rate, and block_align can be used directly from
the AVCodecContext

Return 0 means "please return the same data again", i.e. it causes an
infinite loop. Instead, return an error.

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

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

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

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

GCC does stupid things if these assignments are done using floats
directly, so fill the runs using integer operations instead.  Also
unroll the loops since the length is always a multiple of 4.

The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively.  This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better
match the new operation.
