       set and get menu options

       int set_menu_opts(MENU *menu, Menu_Options opts);
       int menu_opts_on(MENU *menu, Menu_Options opts);
       int menu_opts_off(MENU *menu, Menu_Options opts);
       Menu_Options menu_opts(const MENU *menu);
       The function  set_menu_opts  sets  all  the  given  menu's
       option  bits  (menu  option  bits  may  be logically-OR'ed
       together).
       The function menu_opts_on turns on the given option  bits,
       and leaves others alone.
       The  function  menu_opts_off  turns  off  the given option
       bits, and leaves others alone.
       The function menu_opts returns the menu's  current  option
       bits.
       The following options are defined (all are on by default):
       O_ONEVALUE
            Only one item can be selected for this menu.
       O_SHOWDESC
            Display  the  item  descriptions  when  the  menu  is
            posted.
       O_ROWMAJOR
            Display the menu in row-major order.
       O_IGNORECASE

       O_SHOWMATCH
            Move the cursor to within the item  name  while  pat-
            tern-matching.
       O_NONCYCLIC
            Don't   wrap   around  next-item  and  previous-item,
            requests to the other end of the menu.
       O_MOUSE_MENU
            If user clicks with the mouse and it does not fall on
            the  currently  active  menu,  push KEY_MOUSE and the
            MEVENT data back on the queue to allow processing  in
            another part of the calling program.
       Except for menu_opts, each routine returns one of the fol-
       lowing:

       were not supported on Version 7 or BSD versions.
