[gtk+/wip/matthiasc/kill-event-signals] Drop ::grab-broken-event

[Matthias Clasen <matthiasc src gnome org>]

commit cc5a8b054f974077b610f646d1653ee83a21baaf
Author: Matthias Clasen <mclasen redhat com>

    Drop ::grab-broken-event
    
    This signal is no longer used in GTK+. Grab broken events
    can be handled with the generic ::event signal.
