BitmapWalkListener: Use plain interface with noop instance
In this new interface default methods are useful only to instantiate
noop instances. We rather reuse the same noop instance and save the
"default" to add backward compatible methods to existing interfaces.
Make the methods regular interface methods and provide a noop
instance.
