7046444327 Do not read on the last iteration. 
When the pdu processing limit is hit, we still attempt to read another
PDU. If we succeed, the ber_get_next call in the read callback will
abort since a full PDU is already present.

cf05722b6c Lookup operations by saved connid. 
We reset the connection pointer on a destruction attempt, avoid the
spurious asserts.

58a880bc7b Convert backend and upstream management to use CIRCLEQ. 
This alone doesn't make the server do a round robin.

643194e79e Revert connection/operation mutex order. 
There was still a race where the connection could be freed as the
operation was still being used.

8eb7f3fbca Stop the read callback on a dead connection. 
The connection might be ready to read (close) but if we can't destroy it
yet, we don't want the callback to trigger all the time or process new
data.

028f28690f On a failed bind, stop the callback from firing again 
Not a problem but causes a slew of calls to upstream_bind_cb that will
all fail in the same way.
