pvpanic: implement crashloaded event handling
Handle bit 1 write, then post event to monitor.
Suggested by Paolo, declear a new event, using GUEST_PANICKED could
cause upper layers to react by shutting down or rebooting the guest.
In advance for extention, add GuestPanicInformation in event message.
