utils/ssh updates

[John Meinel]

I don't quite understand the rush each time to break backwards
compatibility. I guess Go doesn't let you have compile time flags, so if
you want to use any new functionality there's no good way to do it
optionally.
Anyway, as long as 1.2 gets backported to Precise and Saucy we could do so.
I certainly prefer to do it when we actually need something,  though I
guess updated gocrypto counts.
