[issue4071] ntpath.abspath fails for long str paths

[Hirokazu Yamamoto]

I think attached patch "fix_getfullpathname.patch" will fix unicode
issue at least. For ansi issue, I followed the manner of win32_chdir for
now.

After some investigation, GetFullPathNameA fails if output size is more
than MAX_PATH even if input size is less than MAX_PATH. I feel it's
difficult check this before invoking GetFullPathNameA.

This is test for unicode issue.

        for count in xrange(1, 1000):
            name = u"x" * count
            path = ntpath._getfullpathname(name)
            self.assertEqual(os.path.basename(path), name)
