[libvirt] [PATCHv3 00/11] qemu: allow disabling certain virtio revisions

https://bugzilla.redhat.com/show_bug.cgi?id=1227354 v1: https://www.redhat.com/archives/libvir-list/2016-July/msg01235.html v2: https://www.redhat.com/archives/libvir-list/2016-August/msg00412.html * probe for the qemu capability * add the attribute to virtio1-only devices such as virtio-gpu and virtio-input devices * allow multiple revisions to be specified v3: * touch up documentation * rename the capability from "virtio-revision" to "virtio-disable-legacy" * move the formatting in qemuBuildNicDevStr after the address and only do it for virtio * get rid of novelty enum names I left the bitmap usage intact, since enforcing both revision makes sense according to the discussion under: [PATCH 0/6] Use more PCIe, less legacy PCI slots and I considered specifying both features in the XML nicer than adding a new value.
