path2: Adjust the API to remove all the _str mutation methods

Add a new trait BytesContainer that is implemented for both byte vectors
and strings.

Convert Path::from_vec and ::from_str to one function, Path::new().

Remove all the _str-suffixed mutation methods (push, join, with_*,
set_*) and modify the non-suffixed versions to use BytesContainer.
