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.
