 * _TlsFilterImpl wraps a filter that encrypts and decrypts data travelling
 * over a TLS encrypted socket.  The filter also handles the handshaking
 * and certificate verification.
 *
 * The filter exposes its input and output buffers as Dart objects that
 * are backed by an external C array of bytes, so that both Dart code and
 * native code can access the same data.
