Well, not really important.
But I usually like to update to the latest version of all linked libs in
a project. Otherwise if you wait too long, it will be much harder to
upgrade those later once you skipped a few versions. And you *will* have
to upgrade one day because older versions tend to not get security
updates anymore.

So, that's actually my only reason: keeping up with the latest version.

Any new ciphers are good: our users might need them if they connect to
latest systems.

If you don't have any objections, I'll commit my changes soon.
But we will keep them on trunk and have the stable branch keep using
OpenSSL 1.0.2.
