David Robillard 0f2f4d8efc Rewrote MidiRingBuffer to more efficiently pack data (flat pack stamps, sizes, and event data into a single buffer).
Eliminate a double-copy on MIDI playback (MidiRingBuffer -> MidiBuffer).
Various MIDI diskstream/source/SMF fixes (only write when appropriate, handle transport locates, etc).
Fix MIDI rec region size/offset problems.
Code cleanups.
