Handle the EOF situation for a metrics connection. Furthermore, if we failed
to fetch the data from the inbuf properly, mark the socket as closed because
the caller, connection_process_inbuf(), assumes that we did so on error.

The TORPROTOCOL reason causes the client to close the circuit which is not
what we want because other valid streams might be on it.
Instead, CONNECTION_REFUSED will leave it open but will not allow more streams
to be attached to it. The client then open a new circuit to the destination.

Obey the "allow-network-reentry" consensus parameters in order to decide to
allow it or not at the Exit.

Exit relays now reject exit attempts to known relay addresses + ORPort and
also to authorities on the ORPort and DirPort.

In order to deny re-entry in the network, we now keep a bloomfilter of relay
ORPort + address and authorities ORPort + address and DirPort + address
combinations.
So when an Exit stream is handled, we deny anything connecting back into the
network on the ORPorts for relays and on the ORPort+DirPort for the
authorities.
