The driver libxl already detects when the shutdown reason is to reboot,
but it was not firing the  "VIR_DOMAIN_EVENT_ID_REBOOT" when that
happened. I added support for the event to be fired when the reasons
are "restart" or "destroy", later explained in the commit messages why
"destroy" is included"

I have tested this patch series on Qubes OS with Xen 4.19.5.
