       The  function  set_item_opts  sets  all  the  given item's option bits (menu option bits may be logically
       “or”-ed together).

       The function item_opts_on turns on the given option bits, and leaves others alone.

       The function item_opts_off turns off the given option bits, and leaves others alone.

       The function item_opts returns the item's current option bits.

       There is only one defined option bit mask, O_SELECTABLE.  When this is  on,  the  item  may  be  selected
       during menu processing.  This option defaults to on.
