NAME
        AddGList -- Add a linked list of gadgets to a window or requester.

    SYNOPSIS
        RealPosition = AddGList( window, gadget, position, numgad, requester )
        D0                       A0      A1      D0        D1      A2

        uword addglist( struct window *, struct gadget *, uword, word,
                struct requester * );

    FUNCTION
        Adds the list of gadgets to the gadget list of the given window
        or requester linked in at the position in the list specified by
        the position argument.

        See addgadget() for more information about gadget list position,
        and more information about gadgets in general.

        The requester parameter will be ignored unless the GTYP_REQGADGET
        bit is set in the GadgetType field of the first gadget in the list.
        In that case, the gadget list is added to the requester gadgets.
        NOTE: be sure that GTYP_REQGADGET is either set or cleared consistently
        for all gadgets in the list.  NOTE ALSO: The window parameter
        should point to the window that the requester (will) appear in.

        Will add 'Numgad' gadgets from gadget list linked by the field
        NextGadget, or until some NextGadget field is found to be NULL.  Does
        not assume that the Numgad'th gadget has NextGadget equal to NULL.

        NOTE WELL: In order to link your gadget list in, the NextGadget
        field of the Numgad'th (or last) gadget will be modified.  Thus, if
        you are adding the first 3 gadgets from a linked list of five gadgets,
        this call will sever the connection between your third and fourth
        gadgets.

    INPUTS
        window = pointer to the window to get your gadget
        gadget = pointer to the first gadget to be added
        Position = integer position in the list for the new gadget
            (starting from zero as the first position in the list)
        Numgad = the number of gadgets from the linked list to be added
            if Numgad equals -1, the entire null-terminated list of
            gadgets will be added.
        requester = the requester the gadgets will be added to if the
            GTYP_REQGADGET GadgetType flag is set for the first gadget
            in the list

    RESULT
        Returns the position of where the first gadget in the list was actually
        added.
