On-disk format for large number of subdirectories

- EXT4_FEATURE_RO_COMPAT_DIR_NLINK (0x0020?) - allow directories to have
  > 65000 subdirectories (i_nlinks) by setting i_nlinks = 1 for such
  directories.  RO_COMPAT protects old filesystems from unlinking such
  directories incorrectly and losing all files therein.
