Ralph Lange a0a9ee4553 ca: Avoid possible race condition during cac shutdown. ...

While the cac dtor runs and waits for TCP circuit threads to exit,
new circuits could be opened by name resolution replies on existing
(still active) circuits.
Avoid this by setting a flag (lock being held) in the dtor, and
checking it in cac::transferChanToVirtCircuit.
