 * Offer an Unix socket over this stream tube.
 *
 * This method offers an Unix socket over this stream tube. The socket address is given as a
 * a QString, which should contain the path to the socket. Abstract Unix sockets are also supported,
 * and are given as addresses prefixed with a \c NUL byte.
 *
 * If your application uses QLocalServer as the local Unix server implementation, you can use the
 * offerUnixSocket(const QLocalServer *, const QVariantMap &, bool) overload instead to more easily
 * pass the server's listen address.
 *
 * Note that only connection managers for which supportsUnixSocketsOnLocalhost() or
 * supportsAbstractUnixSocketsOnLocalhost() is \c true support exporting Unix sockets.
 *
 * If supportsUnixSocketsWithCredentials() or supportsAbstractUnixSocketsWithCredentials(), as
 * appropriate, returns \c true, the \c requireCredentials parameter can be set to \c true to make
 * the connection manager pass an SCM_CREDS or SCM_CREDENTIALS message as supported by the platform
 * when making a new connection. This enables preventing other local users from connecting to the
 * service, but might not be possible to use with all protocols as the message is in-band in the
 * data stream.
 *
 * Arbitrary parameters can be associated with the offer to bootstrap legacy protocols; these will
 * in particular be available as IncomingStreamTubeChannel::parameters() for a tube receiver
 * implemented using TelepathyQt in the other end.
 *
 * This method requires OutgoingStreamTubeChannel::FeatureCore to be ready.
 *
 * \param socketAddress A valid path to an existing Unix socket or abstract Unix socket.
 * \param parameters A dictionary of arbitrary parameters to send with the tube offer.
 * \param requireCredentials Whether the server requires a SCM_CREDS or SCM_CREDENTIALS message
 *                           upon connection.
 * \return A PendingOperation which will emit PendingOperation::finished
