    Encode/Decode LDAP parameters to/from UTF-8

    The python-ldap API only accepts UTF-8 encoded strings therefore any
    unicode values must be encoded to UTF-8 prior to passing to
    python-ldap and conversely UTF-8 encoded strings returned from
    python-ldap need to be decoded back from UTF-8 into unicode.

    Need to use unicode() rather than str() to properly handle non-ascii
    characters, but to be PY2/PY3 compatible use six.text_type.

    Very few of the ldap tests were using non-ascii values, in fact
    non-ascii values were restricted to only specific tests that
    had 'unicode' in their test name. This is very weak test coverage.
    Replace all occurances of 'fake', the standard string
    used in the tests for test value with 'fäké' where the a has an
    umlaut and the e has a diacritical. Visually they look almost the
    same but will trigger the type of encoding exceptions we've seen
    in the past.

    This is the minimal backport for icehouse from the following
