[mutter/wip/wayland-gtk-mutter: 2/5] wayland: split headers and distribute structure definitions

[Jasper St. Pierre <jstpierre src gnome org>]

commit 0d14cb7f7153a02220a8a79c2703620c94f31abb
Author: Giovanni Campagna <gcampagn redhat com>
Date:   Fri Aug 30 18:03:30 2013 +0200

    wayland: split headers and distribute structure definitions
    
    Instead of having all structures in one huge headers, move them
    in the appropriate place, and create one header for surface state.
