Finally on this step we get what we were aimed for - toURI{1, 2} (and
migration{*} APIs too) now can work thru V3_PARAMS protocol. Execution path
goes thru unchanged virDomainMigrateUnmanaged adapter function which is called
by all target places.
Note that we keep the fact that direct migration never works
thru V3_PARAMS proto. We can't change this aspect without
further investigation.
