Subject: [PATCH] Use version in SSL_METHOD not SSL structure.
When deciding whether to use TLS 1.2 PRF and record hash algorithms
use the version number in the corresponding SSL_METHOD structure
instead of the SSL structure. The SSL structure version is sometimes
inaccurate. Note: OpenSSL 1.0.2 and later effectively do this already.
