Subject: Add in Context IDs to the simulator.  From now on, cpuId is almost
 never used, the primary identifier for a hardware context should be
 contextId().  The concept of threads within a CPU remains, in the form of
 threadId() because sometimes you need to know which context within a cpu to
 manipulate.
