[libvirt] [PATCH v2] libxl: Add a test suite for libxl_domain_config generator

The libxl library allows a libxl_domain_config object to be serialized from/to a JSON string. Use this to allow testing of the XML to libxl_domain_config conversion process. Test XML is converted to libxl_domain_config, which is then serialized to json. A json template corresponding to the test XML is converted to a libxl_domain_config object using libxl_domain_config_from_json(), and then serialized back to json using libxl_domain_config_to_json(). The two json docs are then compared. Using libxl to convert the json template to a libxl_domain_config object and then back to json provides a simple way to account for any changes or additions to the json representation across Xen releases.
