matroska: implement support for ALAC
Support Matroska native formatting.
On demuxing reconstruct the 36-bytes QuickTime atom that the ALAC
decoder expects by prepending the "atom size", "tag" and
"tag version" fields missing from the Matroska's CodecPrivate
element.
On muxing remove the initial 12 bytes
Sample files are available:

and the CoreAudio file it was created from with today's mkvmerge:
