Correctly handle exposure in oldXMenu

* oldXMenu/Activate.c (XMenuActivate): Call set expose_func if
no pane was found.
(XMenuActivateSetExposeFunction): New function.
* oldXMenu/XMenu.h: New typedef `expose_func'.  Update
prototypes.
* src/xmenu.c (x_menu_expose_event): New function.
(x_menu_show): Set expose event handler.
* src/xterm.c (x_dispatch_event): Make `static' only on GTK.
* src/xterm.h: Expose `x_dispatch_event' on no-toolkit builds.
