Here is some work left on this patch:
Cleanup issues:
* Remove global variables.
* add cleanup code so it is safe to disable and re-enable jack-midi.
This means, only enable jack-midi in synth/device page, dont disable it.

Known bugs:
* Hung notes. A possible cause can be that we only handle 32 events per
channel in the time-size that is one jack-buffer.
* The program change takes two bytes, but we give three (the third has
value zero). Not sure how jack handles this.
* Midi to/from jack has slashed timing. We read and write midi data
  without regards to framing positions. Midi events are therefor
"quantized" to the time-size of the jack-buffer.
