[PATCH v3 16/21] qemu: hotplug: Implement multifunction device hotplug

From: Shivaprasad G Bhat <sbhat(a)linux.vnet.ibm.com&gt; The support to allow multifunction device hotplug consists of using virDomainDeviceDefListPtr lists instead of single virDomainDeviceDefPtr device definitions in both qemuDomainAttachDeviceConfig() and qemuDomainAttachDeviceLive(). In AttachDeviceConfig() the same existing single device code is ran for all devs in the list. AttachDeviceLive() will verify if the list has size = 1 (meaning it is a single device attach) and redirect the code to the regular single dev attach procedure. If list size > 1, we'll execute a new specialized function called qemuDomainAttachMultifunctionDevice(), which is prepared to handle the nuances of this type of hotplug. The changes in both AttachDeviceLive() and AttachDeviceConfig() implied in changes to be made in qemuDomainAttachDeviceLiveAndConfig(), which is now handling a device list instead of a single device. No changes in regular device hotplug mechanics were made.
