Creates a D-Bus error name to use for @error. If @error matches
a registered error (cf. g_dbus_error_register_error()), the corresponding
D-Bus error name will be returned.
Otherwise the a name of the form
org.gtk.GDBus.UnmappedGError.Quark._ESCAPED_QUARK_NAME.Code_ERROR_CODE
will be used. This allows other GDBus applications to map the error
on the wire back to a #GError using g_dbus_error_new_for_dbus_error().
This function is typically only used in object mappings to put a
#GError on the wire. Regular applications should not use it.
