[libvirt] [PATCH] conf: Mark missing optional USB devices in domain XML
When startupPolicy set for a USB devices allows such device to be
missing, there was no way this could be detected from domain XML. With
this patch, libvirt emits a new missing='yes' attribute for such devices
when active domain XML is generated.
