* renegotiate to a lower one in the premaster secret. This
* didn't happen with TLS 1.0 as most servers supported it
* but it can with TLS 1.1 or later if the server only supports
* 1.0.
*
* Possible scenario with previous logic:
* 1. Client hello indicates TLS 1.2
* 2. Server hello says TLS 1.0
* 3. RSA encrypted premaster secret uses 1.2.
* 4. Handhaked proceeds using TLS 1.0.
* 5. Server sends hello request to renegotiate.
* 6. Client hello indicates TLS v1.0 as we now
* know that is maximum server supports.
* 7. Server chokes on RSA encrypted premaster secret
* containing version 1.0.
*
* For interoperability it should be OK to always use the
* maximum version we support in client hello and then rely
* on the checking of version to ensure the servers isn't
* being inconsistent: for example initially negotiating with
* TLS 1.0 and renegotiating with TLS 1.2. We do this by using
