* xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes

that always fit in int.  Use a sentinel instead of a counter, to
avoid a temp and to allay GCC's concerns about possible int overflow.

* menu.c (grow_menu_items): Check for int overflow.
* xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
