libvirt has supported the migration V3 protocol for many years now.
A nice feature of the virDomainMigrate3 API is that it will detect
the protocol version supported by the underlying hypervisor,
including whether it supports the extensible parameters variant,
and call the hypervisor API with parameters fixed up as needed.

Change virt-manager to use the virDomainMigrate3 API, allowing
migration to work with hypervisors that only support the extensible
parameters variant of the migration V3 API.
