    gnome-rr: Add definition for next rotation
    
    In gnome-settings-daemon's XRandR plugin, we were relying on -1
    meaning "next rotation" so that the "rotate display" button would
    work as expected. But given its values, GnomeRRRotation would
    probably have been made unsigned, and thus never matching -1.
    
    We now add an "next rotation" member for the benefit of that
    XRandR plugin.
