[gnome-shell] Implementing building two separate binaries for x11 and wayland

commit 21a85832b3f838b176ce09e00319a6e68146ee45
Author: Giovanni Campagna <gcampagn redhat com>
Date:   Fri Aug 16 15:47:17 2013 +0200

    Implementing building two separate binaries for x11 and wayland
    
    Build gnome-shell for x11, and gnome-shell-wayland for wayland
    (as well as the associated libgnome-shell and libgnome-shell-wayland).
    The first one links to libmutter, the second to libmutter-wayland.
    
    libgnome-shell and libgnome-shell-wayland are now compiled from
    libgnome-shell-base (with all sources that are independent of mutter),
    libgnome-shell-menu (with the copy-pasted gtk sources), plus the
    sources that use mutter API
