        Bug 107000 – Add signals to GdkKeymap for monitoring caps_lock, etc.

        * gdk/gdk.symbols:
        * gdk/gdkkeys.[ch]: Add a new GdkKeymap::state-changed signal, and
        a gdk_keymap_get_caps_lock_state function.

        * gdk/x11/gdkkeys-x11.c: Implement it here. For now, only emit
        state-changed when caps lock lockedness changes.

        * gdk/x11/gdkdisplay-x11.c: Also select for modifier lock status
        changes in the XkbSelectEventDetails call.
