[clutter/clutter-1.12] Port to new Wayland and xkbcommon APIs



commit 75934dadbe5765644e28f10e9520b79b93662f03
Author: Daniel Stone <daniel fooishbar org>
Date:   Fri Aug 24 01:16:25 2012 +0200

    Port to new Wayland and xkbcommon APIs
    
    For Wayland, this is mostly the input protocol having changed, although
    there's also the SHM pool API, the cursor API, as well as fullscreen and
    ping.
    
    Also port to the new (months-old) xkbcommon API, as used by Weston 0.95.
    This involves having xkbcommon manage the state for us, where
    appropriate.  Fans of multi-layout keyboards (or just caps lock) will no
    doubt appreciate these changes.
