khambrechtandGitHub f29206afb6 fix: put object on windows when parent directories dont already exists
The previous logic was not allowing put-object on windows when the parent directory did not already exist, and would
not always return the correct error if an ancestor in the path already existed as a file.

The problem is the different behavior of the os.Stat command in Windows compared to *nix in backend/posix/posix.go
in function PutObjectWithPostFunc. The os.Stat returns ENOTDIR on *nix if the parent object is a file instead of a
directory. On Windows, if the parent object does not exist at all, the return code of such os.Stat is ERROR_PATH_NOT_FOUND which is mapped to ENOTDIR. However this is inappropriate in this case. As a result, the
return code of the os.Stat is incorrectly interpreted as if the parent object is a file instead of the parent object does not
exist. Which then leads to a failed upload.

This fix validates the existing parent structure on put to make sure the correct error is returned or the put is successful.

Fixes #1702
