Subject: [PATCH] widgets: Hook ::configure-pad signal emission to
 configuration changes

If a pad device configuration gets changed, or reset, we should trigger
the creation of new pad controllers for the existing toplevels.

Add the plumbing so that saving/resetting a device configuration will
result in the same ::configure-pad signal, and trigger it from the
relevant places.
