Add and use notifiable base class instead of void*.
Use notifiable as the base class for trackable, connection, signal_impl,
self_and_iter and destroy_notify_struct.
Use this notifiable* instead of void* for the destroy/notify callback data.
This is a little more type-safe and self-documenting.
Bug #302152
