Anthony provided a Reviewed-by, and given that this is a direct
conversion of cpu_reset() -> cpu_state_reset() -> CPUState::reset(), I
am preparing a PULL for this series tonight. That does not mean that the
code must stay like this forever. :)

cpu_reset() only handles the full reset of one CPU, as I understand, and
is called both at startup and at machine-level reset.

Anthony's Pin object, as qemu_irq successor, was planned post-4th QOM
series, I believe. -- "Small steps, Allie."
