Remove lots of uv/C++ wrappers
Provide cleaner initialization of uv handles
uv: Provide a helper fn to Result<(), IoError>
uv: Remove closure-based home_for_io for raii

Using an raii wrapper means that there's no need for a '_self' variant and we
can greatly reduce the amount of 'self_'-named variables.
