I tend to disagree here. Adding the direction as a lookup key
is IMO beyond the scope of this patch. That's complicated and
would defer this series by months. Given that the upcomming IPTFS
implementation has a lot of direction specific config options,
it makes sense to take that this patch now. Otherwise we have the
direction specific options in input and output states forever.
