Volker Ruppert b1e8a6369c Some work on the sound module handling and the SB16 midi file output.
- Added the capability to load up to 4 sound drivers and added methods to
  get pointers to the waveout, wavein and midiout services of a driver.
- Rewrite of the SB16 midi file output code. In midimode 2 and 3 the midiout
  service of the 'file' driver is used. Removed obsolete midi file handling.
- Re-implemented the closemidioutput() method to make runtime changes of the
  midi setup work with the new code.
