Peter Hutterer 9f225f8ea5 evdev: remove a race condition opening the wrong device 
Potential race condition:
- udev notifies us that a udev_device became available
- we go for a coffee and chat to the neighbours on the way
- the device is unplugged
- a new device is plugged in, gets the same devnode
- we finish our coffee and come back
- open(udev_device_get_devnode())
- new device is now opened as the old device

To avoid the above race, we compare the syspath of the device at the open fd
with the syspath of the device we originally wanted. If they differ, we fail.

evdev_compare_syspath was simply moved up.

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:
