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.

Simply prints the various events to make it easier to check what's coming out
of libinput. Works for --udev (the default) or for --device /dev/input/event0.
Example output:
event7 DEVICE_ADDED seat0 default
event8 DEVICE_ADDED seat0 default
event4 POINTER_BUTTON +1.35s 272 pressed
event5 POINTER_MOTION +2.31s -3.00/ 2.00
Time is displayed relative to the starting time.
Note: statically linked for easier debugging, but we don't distribute it
(yet) anyway.

This commit introduces build script configuration for building a shared
library 'libinput.so' containing the evdev input device functionality
from weston.
evdev.c, evdev.h and evdev-touchpad.c are ported to not use the data
structures and API in weston and libwayland-server in order to minimize
dependencies.
The API of filter.c and filter.h are renamed to not include the
'weston_' prefix.
