Windows: RDR_DeleteFileEntry test for empty directory
RDR_DeleteFileEntry should check to see that a directory entry
that is a directory is in fact empty. The most frequent use of
RDR_DeleteFileEntry is to check whether the object can be deleted
prior to setting the DeletePending state which in turn results in
the object being deleted during Cleanup. If the directory is not
empty during Cleanup it is too late for the error to be seen by
the application.
