This is the nub of the problem: upstream (OpenBSD) OpenSSH targets
LibreSSL natively (it's also used by Apple for their OS X builds). If we
pick up the 1.1.0 patch, we'd probably have to do it in portable because
there's little point in patching OpenBSD for API that doesn't exist
there. I don't want to have to carry such a major divergence in just the
portable tree.

I don't know what LibreSSL's plans are wrt the 1.1.x API, but convincing
them to adopt it would remove much of the problem.

It's disappointing though that OpenSSL didn't see fit to write their own
set of 1.0.x->1.1.x API shims and ship it alongside 1.0.x releases. It
would have made the transition easier for everyone I think.
