[MMIXER]

Browse source 
- Enumerate MIDI devices and provide all necessary functions to deal with them
[WDMAUD_KERNEL]
- Implement support functions which call the provided functions of mmixer library
- Fix a bug in device interface request ioctl handler
- Midi devices should now be visible, capabilities be retrieved and opened / close
- Writing data is not yet supported
