evdev: First stab at an evdev backend

Browse Source 
This backend is a event backend that can be enabled for EGL (for now).
It uses udev (gudev) to query input devices on a linux system, listens to
keyboard events from input devices and xkbcommon to translate raw key
codes into key keysyms.

This commit only supports key events, more to follow.
