[libvirt] [PATCH 0/5] Support for pcie-root / Q35 machine type

This is *almost* usable. I still need to add support for a dmi-to-pci-bridge before the q35 machine type can be used. 1/5 and 3/5 are just cleaning up some things that bothered me while writing patch 4/5. 2/5 should help out other machine types (e.g. arm) just a bit, by eliminating the extra PIIX3 devices unless the machine actually has a PIIX3 chip. 4/5 has the bulk of the changes - it restructures the PCI address validation/allocation so that it doesn't assume that all PCI addresses are the same, or that all PCI slots are the same. It sets up an enum where different types of PCI addresses can be listed, and the validation code checks that the slot about to be used for a device is actually compatible with that device. 5/5 adds the pcie-root controller which is implicit in the q35 machinetype. Of course since we can only connect pcie devices to this controller, and there are no pcie devices supported, it is not really worth much. However, the next patch (in progress) will add a dmi-to-pci-bridge controller, which *can* plug into the pcie-root and provide plain PCI slots, making a working a35 possible. Note that the auto-allocation doesn't attempt to auto-allocate a slot for any type of device other than plain PCI. This means that even when the dmi-to-pci-bridge controller is added, its address on pcie-root (and a pci-bridge device that must be connected to the dmi-to-pci-bridge controller) will need to be manually specified. Auto-placement will be an exercise for later. Things missing: 1) I need a test case for auto-adding multiple bridges. I will add that this afternoon. 2) I need a test case for a q35 domain. That wil also be added this afternoon.
