Playback: Move internal track list onto buffer
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.
