Playback: Move internal track list onto buffer

Browse source 
Does away the statically-allocated track list which frees quite
a fair amount of in-RAM size.

There's no compile-time hard track limit.

Recommended TODO (but not right away): Have data small enough use
the handle structure as its buffer data area. Almost the entire
handle structure is unused for simple allocations without any
associated filesystem path.
