py3: replace os.environ with encoding.environ (part 1 of 5)

os.environ is a dictionary which has string elements on Python 3. We have
encoding.environ which take care of all these things. This is the first patch
of 5 patch series which tend to replace the occurences of os.environ with
encoding.environ as using os.environ will result in unusual behaviour.

    is equal to 'root'.

    This returns '(fp, is_pending_opened)' tuple.
