Re: [libvirt] [PATCHv2 7/9] qemu: use virDomainNetGetActual*() functions where appropriate

The qemu driver accesses fields in the virDomainNetDef directly, but with the advent of the virDomainActualNetDef, some pieces of information may be found in a different place (the ActualNetDef) if the network connection is of type='network' and that network is of forward type='bridge|private|vepa|passthrough'. The previous patch added functions to mask this difference from callers - they hide the decision making process and just pick the value from the proper place. This patch uses those functions in the qemu driver as a first step in making qemu work with the new network types. At this point, the the virDomainActualNetDef is always NULL, so the GetActualX() function will return exactly what the def->X that's being replaced would have returned (ie bisecting is not compromised).
