Subject: [PATCH] Add sixaxis cable-pairing plugin
Implement the old "sixpair" using libudev and libusb-1.0.
When a Sixaxis device is plugged in, events are filtered, and
the device is selected, poked around to set the default Bluetooth
address, and added to the database of the current default adapter.
