David Robillard a2d2f738cb Move event specific ringbuffer stuff to evoral.
Sane event type interface between evoral and libardour (no more shared magic numbers).
Cleanup Evoral::Sequence iterator, fix bugs, probably introduce new ones.
Move MIDI specific event functions to Evoral::MIDIEvent (is-a Evoral::Event).
