MFC 218625:
 Fix Incorrectly formatted ClientHello SSL/TLS handshake messages could
 cause OpenSSL to parse past the end of the message.

 Note: Applications are only affected if they act as a server and call
 SSL_CTX_set_tlsext_status_cb on the server's SSL_CTX. This includes
 Apache httpd >= 2.3.3, if configured with "SSLUseStapling On".

The very quick MFC is done to get this fix into 7.4 / 8.2.
