Base class for memory system probes accepting Packet instances.
This is a helper base class for memory system probes that instrument Packet handling. Unlike the ProbeListenerObject base class, this class supports instrumentation of multiple ProbeManager instances. However, it's limited to one probe point name. This enables features like tracing or stack distance analysis of packets from multiple components using the same probe. For example, a stack distance probe could be hooked up to multiple memories in a multi-channel configuration.

Callback to analyse intercepted Packets.
Implemented in MemFootprintProbe, StackDistProbe, and MemTraceProbe.

Register probe listeners for this object.
No probe listeners by default, so do nothing in base.
Reimplemented from SimObject.
