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.

d99fe3a478 mpeg12: fix mpeg_decode_slice context parameter type
During slice threading only MpegEncContext is passed to
mpeg_decode_slice, remove a wrong cast and change the function
definition to take MpegEncContext pointer.

cd8c64e197 Revert "mpeg12: move full_pel from MpegEncContext to Mpeg1Context"
This reverts commit da22ba7df461c13bf0b0eabc953303803a285d91 since it
broke slice threading. Slice threading just duplicates MpegEncContext
so every value used during mpeg_decode_slice has to be in it.
A second patch will fix the illusion that Mpeg1Context is available
in mpeg_decode_slice.
