Since mkvmerge doesn't set the bit depth for A_QUICKTIME audio (as far
as I know), the track->audio.bitdepth variable will be zero, and its

confine the 0x00000000 to 'raw '/'twos' fourcc mapping to old version 0
sound sample descriptions, since they are the only valid sample
descriptions for this type of mapping.

I should add that I've limited the setting of track->audio.bitdepth to
version 0 sound sample descriptions only, since as they can only contain
8- or 16-bit uncompressed data, setting it here will properly reflect
the "real" bit depth. The bit depth of version 1 sound sample
descriptions can be larger than 16 bits.
