A wayland compositor needs to have more keyboard state than
ClutterModifierState exposes, so it makes sense for it to use
xkb_state directly. Also, it makes sense for it to provide
it's own keymap, to ensure a consistent view between the compositor
and the wayland clients.

In some cases, applications (or actually, wayland compositors)
don't have the required permissions to access evdev directly, but
can do so with an external helper like weston-launch.
Allow them to do so with a custom callback that replaces the regular
open() path.

Clutter applications using evdev are typically fullscreen applications
associated with a single virtual termainal. When switching away from
the applications associated tty then Clutter should stop managing all
evdev devices and re-probe for devices when the application regains
focus by switching back to the tty. To facilitate this, this patch
adds clutter_evdev_release_devices() and clutter_evdev_reclaim_devices()
functions.
