Add udev bits to assign LIBINPUT_DEVICE_GROUP The easiest way to get a device group is by looking at the phys path of the input device (which looks like usb-0000:00:14.0-1/input1) and dropping the /inputX bit. The rest is the same for devices that belong together (except on the Cintiq 22HD Touch). Ideally we could just take ATTRS{phys} but we can't select substrings to drop into ENV so we need to do it ourselves. This patch adds a callout that takes a syspath and prints the mangled path, to be used in LIBINPUT_DEVICE_GROUP. The rule triggers on any device that has a non-zero phys attribute, this groups devices like tablets together but also devices like mice with multiple interfaces.
