Fix #8879. Add os.link support to Windows.
Additionally, the st_ino attribute of stat structures was not being filled
in. This was left out of the fix to #10027 and was noticed due to
test_tarfile failing when applying the patch for this issue. An earlier
version of the fix to #10027 included st_ino, but that attribute got lost
in the shuffle of a few review/fix cycles. All tests pass.
