[libvirt] [PATCHv2 1/5] conf: use a unique data type for PF array in virDomainNetDef

[Laine Stump]

This array was originally defined using the existing
virNetworkForwardIfDef, but that struct has a UsageCount field that
isn't used in the case of PFs. This patch just copies that struct and
removes UsageCount. It ends up being a struct with a single field, but
I left it as a struct in case we need to add other fields to it in the
future.
