[mutter/wip/carlosg/clutter-keymap: 2/2] evdev: Implement ClutterKeymap

commit 082feabf585f1d1bd25b3824069e126600879cbe
Author: Carlos Garnacho <carlosg gnome org>
Date:   Thu Jan 10 16:13:20 2019 +0100

    evdev: Implement ClutterKeymap
    
    Just move the minimal bits to this ClutterKeymapEvdev object. Much
    of the functionality of a keymap is spread along ClutterSeatEvdev,
    ClutterDeviceManagerEvdev and ClutterVirtualInputDevice. Future
    refactors are due here.
    
    Also, ideally keymaps are per-seat objects (at least keyboard state
    is). We don't expose much info about seats altogether outside the
    evdev device manager implementation. We just poke the main seat at
    places, but eventually seats should be public.
