* fix and enable midi support
* clean up of useless commented code

Greg added: "I even tested the driver, module and midi_server on Haiku ! It was
working, both input and output. Some midi programs don't run, and I
don't know if it is the midi_server or something else, but several apps
run fine.". Good work!
