Proper SSL shutdown handling.
Proper SSL shutdown handling.

If connection has unsent alerts, SSL_shutdown() tries to send them even
if SSL_set_shutdown(SSL_RECEIVED_SHUTDOWN|SSL_SENT_SHUTDOWN) was used.
This can be prevented by SSL_set_quiet_shutdown().  SSL_set_shutdown()
is required nevertheless to preserve session.
