Peter Hutterer 2b2a1b0eb9 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.

libinput
========

libinput is a library that handles input devices for display servers and other
applications that need to directly deal with input devices.

It provides device detection, device handling, input device event processing
and abstraction so minimize the amount of custom input code the user of
libinput need to provide the common set of functionality that users expect.

Input event processing includes scaling touch coordinates, generating
pointer events from touchpads, pointer acceleration, etc.

libinput originates from weston, the Wayland reference compositor.

The source code of libinput can be found at:
