This adds a backend_domname field in libxl devices that contain a backend_domid field, allowing either a domid or a domain name to be specified in the configuration structures. The domain name is resolved into a domain ID in the _setdefault function when adding the device. This change allows the backend of the block devices to be specified (which previously required passing the libxl_ctx down
