We now send the highest supported version by the client, even if the session uses an older version. This fixes 2 problems: - When you try to reuse a session but the other side doesn't reuse it and uses a different protocol version the connection will fail. - When you're trying to reuse a session with an old version you might be stuck trying to reuse the old version while both sides support a newer version Signed-off-by: Kurt Roeckx <kurt@roeckx.be> Reviewed-by: Viktor Dukhovni <viktor@openssl.org> GH: #852, MR: #2452
