A helper function doesn't hurt, does it? The application can decide
whether to use it or not. If libssh2 will include code for reading
known_hosts file in the various formats, also including code for writing
seems consistent. Otherwise the application will have to do it
internally.

Yup, and that belongs in the application.

I think Daniel's API is flexible enough to permit applications to do
whatever they want. The interface is fully opt-in.
