a checkpoint now gives identical results to running from scratch
and doing at switchover at the same cycle!
- CPUs start at cycle 0 again, not cycle 1.
- curTick is now serialized & unserialized.
- Stats get reset in main (before event loop). Since this is done
after curTick is unserialized, simTicks gets set correctly for
running from a checkpoint.
- Simplify serialization to happen in a single pass.

Reset stats before getting started.
Make error message on falling out of event loop
more meaningful.

Get rid of now-useless initial pass; serialization is
done in a single pass now.
Serialize & unserialize curTick.
Wrap curTick and mainEventQueue in a "globals" Serializable object.
