f0b5c0ec7c
This change adopts the upstream fix in this regard at https://go-review.googlesource.com/#/c/41834/ for Minio's purposes. Go's current os.Stat() lacks support for lot of strange windows files such as - share symlinks on SMB2 - symlinks on docker nanoserver - de-duplicated files on NTFS de-duplicated volume. This PR attempts to incorporate the change mentioned here https://blogs.msdn.microsoft.com/oldnewthing/20100212-00/?p=14963/ The article suggests to use Windows I/O manager to dereference the symbolic link. Fixes #4122
