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.

For now, there is still a single global event queue, but this is
necessary for making the steps towards a parallelized m5.

Make sure not to keep processing functional accesses
after they've been responded to.
Also use checkFunctional() return value instead of checking
packet command field where possible, mostly just for consistency.

are generated and initialized by python. The .ini file is now solely for

- factor out checkFunctional() code so it can be
called from derived classes
- use EventWrapper for sendEvent, move event handling
code from event to port where it belongs
- make sendEvent a pointer so derived classes can
override it
- replace std::pair with new class for readability
