tls_disconnect shut down the ssl stream but didn't inform the BIO(s) about this therefore could happen that a second shut down was initiated (e.g. in bio_rdp_tls_free) causing rather long delays. After removing the shut down from tls_disconnect the only thing the function does is to prepare/send an alert therefore it was renamed to tls_send_alert.
