    gdk: activate surface on keyboard grabs
    
    In 01455399e83a ("gdk: do not deactivate surface on keyboard grabs"), we
    made gdk avoid deactivating surfaces when another application takes a
    keyboard grab, by using has_focus_window instead of has_focus. That however
    broke activating surfaces when the gdk application acquired a grab itself,
    in which case has_focus_window is false but has_focus is true.
    
    We thus actually need to use both: surfaces should be activated either
    because we have normal keyboard focus, or because we grabbed the keyboard.
    
    This also renames HAS_FOCUS to APPEARS_FOCUSED to better reflect its
    role.
    
    Fixes #85
