Adds a signal handler to @msg for @signal, as with
g_signal_connect(), but the @callback will only be run if @msg has
the status @status_code.
@signal must be a signal that will be emitted after @msg's status
is set. For a client #SoupMessage, this means it can't be a "wrote"
signal. For a server #SoupMessage, this means it can't be a "got"
signal.
