        (gdk_keyboard_grab):
        (gdk_display_keyboard_ungrab):
        (gdk_keyboard_grab_info_libgtk_only):
        (find_window_for_event):
        Implement keyboard grabs.

        * gdk/quartz/gdkmain-quartz.c:
        * gdk/quartz/gdkprivate-quartz.h:
        New function that synthesizes map events.
