Support for filtering pkt ins, cleanup

Replaced barrier_to with transact_to.  Allow filtering of packet-in
messages which is disabled by default.  A threshold is set and,
when enabled, if N packet ins are received without other messages
intervening (and without packet-in being expected) subsequent
packet ins are dropped.

With packet storms on OVS, this has detected some overrun errors
on buffering and framing gets messed up.

Cleaned up some termination code; _socket_ready_handle now
returns an error code rather than True/False.
