SSH: Use OpenSSH tools

... instead of our own SSH library.

Advantages:
    - Full compatibility with OpenSSH behavior guaranteed.
    - Minimal maintenance effort.
    - Less code to build.
    - Big chunk of 3rd party sources can be removed from our repository.

One the downside, Windows users now need to install OpenSSH for
RemoteLinux support. Hoewever, people doing embedded development
probably have it installed anyway.
