[gtk+] Drop ::map-event and ::unmap-event

[Matthias Clasen <matthiasc src gnome org>]

commit fd2a3b602f3d82b147657b261b1f6ca112fe7977

    Drop ::map-event and ::unmap-event
    
    These are unused in GTK+, and are not very common.
    If you need to catch these events, the generic ::event
    signal still works.
