Terminates the current TLS/SSL connection. The connection should
have been initiated using gnutls_handshake(). how should be one
of GNUTLS_SHUT_RDWR, GNUTLS_SHUT_WR.
In case of GNUTLS_SHUT_RDWR the TLS session gets terminated and
further receives and sends will be disallowed. If the return
value is zero you may continue using the underlying transport
layer. GNUTLS_SHUT_RDWR sends an alert containing a close request
and waits for the peer to reply with the same message.
In case of GNUTLS_SHUT_WR the TLS session gets terminated and
further sends will be disallowed. In order to reuse the
connection you should wait for an EOF from the peer.
GNUTLS_SHUT_WR sends an alert containing a close request.
Note that not all implementations will properly terminate a TLS
connection. Some of them, usually for performance reasons, will
terminate only the underlying transport layer, and thus not
distinguishing between a malicious party prematurely terminating
the connection and normal termination.
This function may also return GNUTLS_E_AGAIN or
GNUTLS_E_INTERRUPTED; cf. gnutls_record_get_direction().
