Added new HTTP status codes and default response bodies from the

revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
HTTP Extension Framework (510) specifications.  Did not add the
WebDAV 424 and 425 codes because they are bogus.  We don't use any
of these codes yet, but they are now available to 3rd-party modules.
