[mutter] backends: Make MetaBackend available to introspection

commit 7d54631ebf96454f261504538312f0002ca19403
Author: Rui Matos <tiagomatos gmail com>
Date:   Tue Aug 5 14:11:59 2014 +0200

    backends: Make MetaBackend available to introspection
    
    This moves meta-backend.h under meta/ and, for now, just exposes to
    introspection the methods that we actually need in gnome-shell.
