[issue1578269] Add os.link() and os.symlink() and os.path.islink() support for Windows

No, the test should *not* fail. A failing test means "the test has
completed, and the outcome was not expected, due to a bug somewhere
(the operating system, Python, or the test case proper)". This is not
the case if the link cannot be created - the resulting behavior is
exactly the correct, and expected one (under the circumstances).

Most definitely. That's what the notion of a "skipped" test is for
(as opposed to a "failed" one).
