Staging: add line6 usb driver
This is an experimental Linux driver for the guitar amp, cab, and
effects modeller PODxt Pro by Line6 (and similar devices), supporting
the following features:
- Reading/writing individual parameters
- Reading/writing complete channel, effects setup, and amp setup data
- Channel switching
- Virtual MIDI interface
- Tuner access
- Playback/capture/mixer device for any ALSA-compatible PCM audio
application
- Signal routing (record clean/processed guitar signal, re-amping)
Moreover, preliminary support for the Variax Workbench is included.
