set_item_userptr, item_userptr - associate application data with a menu item

       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 that 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.

       The function item_userptr returns a pointer (possibly NULL).  It does not set errno.

       The set_item_userptr always returns E_OK (success).
