                * gtk/gtkmain.c: allow exclusive grabs.

                        * gtk/gtkmenu.c: grab exclusively.
                                * gtk/gtkmenushell.c: grab exclusively.

                                        * gtk/gtkmenushell.c: don't activate insensitive menu items when
                                                in click-selects mode.

                                                        * gtk/gtkmenushell.c (gtk_menu_shell_enter_notify): activate submenus
                                                                on popup.

                                                                        * gtk/gtkmenushell.c (gtk_menu_shell_button_release): don't take
                                                                                *additional* button presses into account.

                                                                                        * gtk/gtkmenushell.c (gtk_menu_shell_button_press): don't take
                                                                                                foreign button releases into account.
