Martin Gräßlin ab5d31426a [libinput] Expose all input devices through DBus
Summary:
The Connection exposes a new service called org.kde.KWin.InputDevice
and every Device registers an own object exposing all properties.

This allows an external configuration tool to change the behavior of
the devices at runtime. E.g. to test configuration settings.
