With split hardware and control domains, each domain should be
privileged with respect to xenstore. When adding domains to xenstore,
look at their privilege and add them to xenstored as appropriate.
dom0_domid is used for the hardware domain, and priv_domid is used for a
control domain.
Only one of each is allowed for now.
