[gtk+/wip/matthiasc/kill-event-signals: 96/126] Drop ::grab-broken-event

[Matthias Clasen <matthiasc src gnome org>]

commit 18c61033a798081656789d33a20ccd62ac16efe6
Author: Matthias Clasen <mclasen redhat com>
Date:   Tue Jan 2 17:05:08 2018 -0500

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