0093f96d34 pcmdec: return buf_size instead of src-buf. 
The values will always be the same, so this change eliminates an unneeded
variable. It also gets rid of the need to reset src when memcpy() is used.

85579b6381 avcodec: remove the Zork PCM encoder. 
The Zork PCM decoder does not decode the 1 sample we have correctly, therefore
the encoder based on the decoder is also incorrect. There is no good reason to
keep the encoder.

06af335a33 pcmenc: remove unneeded sample_fmt check.

7080533cda alacdec: remove the numchannels parameter from several functions. 
They only operate on stereo content, so the extra param is not necessary and
also allows for simplifying the code.

c39bddd392 alacdec: move appending of extra_bits to a separate function. 
This should also fix decoding of mono 24-bit.

e739d35156 alacdec: split stereo decorrelation into a separate function. 
It is identical for 16-bit and 24-bit, so there is no need to have duplicate
code.

d251c85dce alacdec: cosmetics: rename 'wasted_bits' to 'extra_bits'. 
The bits are not wasted, they are additional low bits that are added to the
16-bit decompressed samples to increase the output sample depth.

d0a196962a g722dec: remove the use of lowres for half-rate decoding. 
It is broken because an AVCodecContext can be opened/closed multiple
times, and sample_rate is getting divided by 2 each time that happens.

This removes the only use of lowres for audio.

c6056d4004 tta: add support for decoding 24-bit sample format 
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.
