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

[Daniel Henrique Barboza]

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.
