Made cfs implementation adhere to (new) cfs interface, streamlined implementation, reduced header dependencies and removed the 'cfs-root/' prefix. The reasoning behind the latter:

- Productive embedded targets don't use the posix based variant anyway.
- For testing purposes the prefix is a hurdle as the documentation doesn't mention it ;-))
- The prefix is incompatible with posix implementations lacking directory support (like the C64).
