[libvirt] [PATCH v4 1/2] Add USB option capability

From: Li Zhang <zhlcindy@linux.vnet.ibm.com> To avoid the collision for creating USB controllers in machine->init() and -device xx command line, it needs to set usb=off to avoid one USB controller created in machine->init(). So that libvirt can use -device or -usb to create USB controller sucessfully. So QEMU_CAPS_MACHINE_USB_OPT capability is added, and it is for QEMU v1.3.0 onwards which supports USB option.

ACK, but we should merge it into the previous patch before adding to git - basically always include the test cases in the same patch that you include the new feature in.
