Comment (by daira):

 [https://bugs.python.org/issue21719] says that there is no Python 2.7 API
 for this. Therefore, a `ctypes` call to either [https://msdn.microsoft.com
 /en-us/library/windows/desktop/aa364944.aspx GetFileAttributesW] or
 [https://msdn.microsoft.com/en-us/library/windows/desktop/aa364946.aspx
 GetFileAttributesEx] is needed. Note that we already `lstat` the file in
 `get_pathinfo` before deciding whether to upload it, but I guess that
 determining whether it is hidden/system does not need to be atomic with
 that, therefore the simpler `GetFileAttributesW` API would be sufficient.
 The `ctypes` call should be implemented in `fileutil.py`.
