[libvirt] [PATCH v3 0/6] PCI hostdev partial assignment support

changes from previous version [1]: - do not overload address type='none'. A new address type called 'unassigned' is introduced; - there is no unassigned' flag being created in virDomainHostdevDef. The logic added by new address type is enough; - do not allow function zero of multifunction devices to be unassigned. Nothing too special to discuss in this cover letter. More details can be found at the discussions of the previous version [1]. Commit messages of the patches have more background info as well.
