MaxCycleCount is accounted by countdown, eliminating the 1-instruction-overhead issue, and removing the need to compare against a growing TotalCycles. Makes main.c responsible for counting total cycles, instead of 6502.c, so the size of MaxCycleCount etc. is fully determined in one location. Makes error.c responsible for PrintCycles instead of paravirt.c, so that it can be treated globally instead of Return value of main() should be SIM65_ERROR because it is unreachable by design.
