* test/glib/test-service-glib.c (main): remove unused variable

	* glib/dbus-gidl.c (base_info_ref): fix a silly compiler warning

	* dbus/dbus-auth.h (enum): remove AUTHENTICATED_WITH_UNUSED_BYTES
	from the enum, no longer in use.

	* dbus/dbus-sysdeps.h: include config.h so DBUS_VA_COPY actually
	works right.

	* dbus/dbus-message.c: add various _dbus_return_val_if_fail for
	whether error_name passed in is a valid error name.
