        * gtk/gtksignal.c: added new functions to operate on intermediate
                function pointers. implemented incremental blocking.
                        (gtk_signal_disconnect_by_func): new function.
                                (gtk_signal_handler_block_by_func): new function.
                                        (gtk_signal_handler_unblock_by_func): new function
