        * applied unified patch for configurable scroll arrow sizes from
        bug #333632 and bug #325282.

        * gtk/gtkwidget.c (gtk_widget_class_init): added ::scroll-arrow-hlength
        and ::scroll-arrow-vlength style properties. fixed upper limit for
        ::separator-width and ::separator-height to be MAXINT.

        * gtk/gtkmenu.c: use GtkWidget::scroll-arrow-vlength to determine the
        scroll arrow size, instead of using a hard coded constant.

        * gtk/gtknotebook.c: use GtkWidget::scroll-arrow-vlength and
        GtkWidget::scroll-arrow-hlength to determine scroll arrow sizes.
        added GtkNotebook::arrow-spacing style property to configure the
        spacing between scroll arrows.
