so nss required a little work to make the equivalent of SSL_get_version()
work during the alpn callback. Is this something that should be pursued in
the openssl bug tracker? (Have you double checked that?) Its more of an
open source implementation thing than a working group item..

in practice the client shouldn't be offering h2 if it isn't also offering
1.2 so this shouldn't come up as long as you're configured to
unconditionally prefer 1.2.. weird behavior should be limited to clients
that made non sensical offers.
