[libvirt] [PATCHv2 3/5] conf: output forward device connections count in network XML

[Laine Stump]

It may be useful for management applications to know which physical
network devices are in use by guests. This information is already
available in the network objects, but wasn't output in the XML. This
patch outputs it whan the INACTIVE flag isn't set (and if it's non-0).
