introduce a new qom device to deal with panicked event

Browse source 
pvpanic device is used to send guest panic event from guest to qemu.

When guest panic happens, pvpanic device driver will write a event
number to IO port 0x505(which is the IO port occupied by pvpanic device,
by default). On receiving the event, pvpanic device will pause guest
cpu(s), and send a qmp event QEVENT_GUEST_PANICKED.
