  * Fix defect when unpacking tar files containing links
  There were two issues;
    * Unpacking links that point to files not yet unpacked
    * Used the link target as absolute path, but it's relative
  This patch addresses both issues, which is ticket #246.
  There may still be errors if a link refer to another link which has not
  been unpacked yet.
