Changeset 10876:9613201373b3

---------------------------

mem: Add probe support to the CommMonitor
This changeset adds a standardized probe point type to monitor packets

in the memory system and adds two probe points to the CommMonitor

class. These probe points enable monitoring of successfully delivered

requests and successfully delivered responses.
Memory system probe listeners should use the BaseMemProbe base class

to provide a unified configuration interface and reuse listener

registration code. Unlike the ProbeListenerObject class, the

BaseMemProbe allows objects to be wired to multiple ProbeManager

instances as long as they use the same probe point name.
