Possible assertion failure in connection_ap_handshake_attach_circuit()
Vektor reports that an AdvOR user reported a failure of the assertion
tor_assert(introcirc->_base.purpose == CIRCUIT_PURPOSE_C_INTRODUCING);
in connection_ap_handshake_attach_circuit().
His fix is to replace the test in circuit_is_acceptable() so that CIRCUIT_PURPOSE_C_INTRODUCE_ACK_WAIT circuits can no longer get returned.
We should investigate. Filing for 0.2.2 since ISTR that's what AdvOR is tracking.
