Volker Ruppert 16d2957cd4 Rewrite of the ES1370 wave output code and related changes.
- Implemented wave output using the 'soundfile' driver including dual wave
  output in wavemode 3. Removed now obsolete output file handling and other
  cleanups. The wave input (recording) feature is not affected by the
  wavemode setting.
- Moved VOC file handling to the soundfile code.
- Updated iodev makefile dependencies.
