ovl: index directories on copy up for NFS export
With the NFS export feature enabled, all dirs are indexed on copy up. Non-dir files are copied up directly to indexdir and then hardlinked to upper dir. Directories are copied up to indexdir, then an index entry is created in indexdir with 'upper' xattr pointing to the copied up dir and then the copied up dir is moved to upper dir. Directory index is also used for consistency verification, like detecting multiple redirected dirs to the same lower dir on lookup.
