* CoreMIDI driver: implemented driver specific port parameter
  "CORE_MIDI_BINDINGS", which allows to retrieve the list of CoreMIDI
  clients / ports and to connect to them a la JACK, via the usual
  sampler APIs
* CoreMIDI driver: added driver specific port parameter "AUTO_BIND", if
  enabled the driver will automatically connect to other CoreMIDI
  clients' ports (e.g. external MIDI devices being attached to the Mac)
