[libvirt] [PATCH V3 6/6] libxl: Add support for ovmf firmware

Populate libxl_domain_build_info struct with bios and firmware info from virDomainLoaderDef. Note: Currently libxl only allows specifying the type of BIOS. For type LIBXL_BIOS_TYPE_OVMF, the firmware path is configured when building Xen using '--with-system-ovmf='. If not specified, LIBXL_FIRMWARE_DIR/ovmf.bin is used. In the future, Xen will support a user-specified firmware path. See http://lists.xenproject.org/archives/html/xen-devel/2016-03/msg01628.html Once that work is merged into xen.git, the libvirt libxl driver will be able to honor a user-specified path. In the meantime use the implicit path, which is tolerable since it is advertised in domcapabilities.
