* Add `fs.ResolvePath` to resolve symbolic links `filepath.EvalSymlinks` does not work well on Windows, and can enter infinite loops in certain situations and error out. Use Win32 API GetFinalPathNameByHandle to handle path resolution. Implementation based off on: https://github.com/containerd/containerd/pull/5411 Signed-off-by: Hamza El-Saawy <hamzaelsaawy@microsoft.com> * PR: types, documentation Signed-off-by: Hamza El-Saawy <hamzaelsaawy@microsoft.com> * remove unneded constant groups Signed-off-by: Hamza El-Saawy <hamzaelsaawy@microsoft.com> * Attempt normalized path first Update logic to try querying for normalized path initially, then use opened path if access is denied.
