encrypted dir conns confuse LeaveStreamsUnattached
(This is Mikeperry's bug)
When we launch an encrypted dir conn in directory.c via connection_ap_make_link(), it'll put the stream in state AP_CONN_STATE_CIRCUIT_WAIT. This means that even controllers that set LeaveStreamsUnattached won't need to handle it, since it's already being handled.
Bug #1: controllers don't know this, and can't distinguish streams that are already being handled. Mike had a patch to put an extra flag on the stream status line.
Bug legacy/trac#2 (closed): then if the stream causes a circuit to get created, and gets attached to that circuit, but the circuit times out or otherwise fails to fulfill the request, the stream will be handled by connection_ap_detach_retriable() which will set it to state AP_CONN_STATE_CONTROLLER_WAIT. And the controller doesn't realize that this time it's supposed to handle it (and it probably shouldn't need to handle it)
