arrows. Control their display by new style properties
"has_forward_stepper", "has_backward_stepper",
"has_secondary_forward_stepper" and
has_secondary_backward_stepper". (#110540)
* gtk/gtknotebook.h (struct _GtkNotebook): Make in_child and
click_child three bits wide, add
has_{before,after}_{previous,next} fields.
