+ * wget.h (err_t): Added new errors, ATTRMISSING and UNKNOWNATTR to
+ handle missing attributes and Unknown attribute values respectively in
+ HTTP Headers.
+ * exits.c (get_status_for_err): ATTRMISSING is a Protocol Error while
+ UNKNOWNATTR is a general error, presumably because of a feature that
+ is not yet implemented.
+ * http.c (gethttp): Call create_authorization_line () separately. In
+ case the auth_err flag has been set with an error, handle it and exit.
+ * http.c (create_authorization_line): Pass a pointer, auth_err to set
+ the flag for different kinds of errors encountered.
+ * http.c (http_loop): Handle the errors raised by the authentication
+ handlers.
+ * http.c (digest_authentication_encode): Pass pointer auth_err to set
+ the error flags.
+ Set qop to NULL in case the value of the qop / algorithm attribute is
+ unknown to Wget. Set an appropriate error too.
