Report the new VIR_DOMAIN_EVENT_STOPPED_REBOOT reason when reboot has
been requested. I have only tested this on Xen, so I made a patch per
VMM. I preferred to rely on the stopped reason, as there is no
discussion that it should be sent, while for the reboot event, there is
debate that it shouldn't always be sent.
