 - uio_Stream file might get unaligned (not sure).
 - 'openDir(repository, "dir/")' will have the trailing '/'

+- 'openDirRelative(repository, "/")' causes segfaults lateron
 - uio_rename() doesn't work on directories
   uio_getPhysicalAccess() needs to be changed so that it works the same on
   dirs as on files. stat() can be cleaned up too then.
