zhenwei pi 7dc58deea7 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.

zhenwei pi 600d7b47e8 pvpanic: introduce crashloaded for pvpanic
Add bit 1 for pvpanic. This bit means that guest hits a panic, but
guest wants to handle error by itself. Typical case: Linux guest runs
kdump in panic. It will help us to separate the abnormal reboot from
normal operation.
