From: Luca Miccio <lucmiccio@gmail.com>
When xs_introduce_domain is called, send out a notification on the
xenstore event channel so that any (dom0less) domain waiting for the
xenstore interface to be ready can continue with the initialization.
The extra notification is harmless for domains that don't require it.
