      Description

      TLS renegotiation is complicated, has been removed from TLS 1.3, and is not supported on the OS X and Windows native cryptography implementations. For consistency going forward, we should disable it on OpenSSL, if we are able to.

      Some versions of OpenSSL define SSL_OP_NO_RENEGOTIATION, which disabled renegotiation on TLS 1.2 and before. If this macro is defined, we should apply it to our SSL_CTX objects with SSL_CTX_set_options.
