   * Emitted during the TLS handshake after the peer certificate has
   * been received. You can examine @a peer_cert's certification path by
   * calling g_tls_certificate_get_issuer() on it.
   * 
   * For a client-side connection, @a peer_cert is the server's
   * certificate, and the signal will only be emitted if the
   * certificate was not acceptable according to @a conn's
   * TlsClientConnection::property_validation()_flags. If you would like the
   * certificate to be accepted despite @a errors, return <tt>true</tt> from the
   * signal handler. Otherwise, if no handler accepts the certificate,
   * the handshake will fail with TLS_ERROR_BAD_CERTIFICATE.
   * 
   * For a server-side connection, @a peer_cert is the certificate
   * presented by the client, if this was requested via the server's
   * TlsServerConnection::property_authentication()_mode. On the server side,
   * the signal is always emitted when the client presents a
   * certificate, and the certificate will only be accepted if a
   * handler returns <tt>true</tt>.
   * 
   * Note that if this signal is emitted as part of asynchronous I/O
   * in the main thread, then you should not attempt to interact with
   * the user before returning from the signal handler. If you want to
   * let the user decide whether or not to accept the certificate, you
   * would have to return <tt>false</tt> from the signal handler on the first
   * attempt, and then after the connection attempt returns a
   * TLS_ERROR_BAD_CERTIFICATE, you can interact with the user, and
   * if the user decides to accept the certificate, remember that fact,
   * create a new connection, and return <tt>true</tt> from the signal handler
   * the next time.
   * 
   * If you are doing I/O in another thread, you do not
   * need to worry about this, and can simply block in the signal
   * handler until the UI thread returns an answer.
