This series implements a new interface, kvm pv event, to notify host when
some events happen in guest. Right now there is one supported event: guest
panic.

changes from v11:

- add a new patch 'save/load cpu runstate'
- fix a bug of null-dereference when no -machine option is supplied
- reserve RUN_STATE_GUEST_PANICKED during migration
- add doc of enable_pv_event option
- disable reboot-on-panic if pv_event is on
