alacdec: implement the 2-pass prediction type.
...
The reference encoder does not generate any streams using this, but the
reference decoder can handle it, so we should as well.

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.

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.

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.

Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an
...
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

be a change done here or there if some developer has some cleanup ideas and
