Determine if this request port is snooping or not.
The default implementation returns false and thus tells the neighbour we are not snooping. Any request port that wants to receive snoop requests (e.g. a cache connected to a bus) has to override this function.

Called to receive an address range change from the peer response port.
The default implementation ignores the change and does nothing. Override this function in a derived class if the owner needs to be aware of the address ranges, e.g. in an interconnect component like a bus.
