Robin Gareus 65346496f5
Refactor Ctrl Surface API 
* reserve "probe" to actually probe for devices
* use separate probe for libusb and MIDI port devices
* use "available" to check if surface can be used
* allow both methods to be NULL
* remove unused ControlProtocolDescriptor* argument

Most surface just return `true` for available.
