[issue12084] os.stat() on windows doesn't consider relative symlink

[Hirokazu Yamamoto]

New submission from Hirokazu Yamamoto <ocean-city at m2.ccsnet.ne.jp>:

Hello. I noticed os.stat() on windows may traverse wrong path on relative symbolic when current working directory != the directory where symbolic link is in. This is because the relative path DeviceIoControl() returns is just passed to win32_xstat without converting to absolute path.

I'm sorry because I implemented this function, and it's hard for me to debug this because I don't have Vista/7. This patch uses GetFinalPathNameByHandle like original code does, plus should handle symlink to system locked file.

Can anyone test and commit this patch?
