set_menu_userptr, menu_userptr - associate application data with a menu item

       Juergen Pfeifer.  Manual pages and adaptation for new curses by Eric S. Raymond.

       Every  menu  and every menu item has a field that can be used to hold application-specific data (that is,
       the menu-driver code leaves it alone).  These functions get and set the menu user pointer field.

       These routines emulate the System V menu library.  They were not supported on Version 7 or BSD versions.

       The user pointer is a void pointer.  We chose not to leave it as a char pointer for SVr4 compatibility.

menu_userptr returns a pointer (which may be NULL).  It does not set errno.

       set_menu_userptr returns E_OK (success).
