Comment (by teor):

 We will backport the new fallback list format to 0.2.8 and later, so we
 might need two versions of this code:
 * a backport version that ignores the extrainfo tag
 * a master version that parses the tag, uses it to set the extrainfo type
 via fallback_dir_server_new(), and correctly handles the extrainfo type
 when bootstrapping.
