Olaf Barthel 99547756fe - Major, major changes! Moved most of the monolithic code out of
the file descriptor hook and into the respective functions,
  such as dup2(), fchmod(), fchown(), fcntl(), fdatasync(), fstatfs(),
  fsync(), ftruncate() and lseek(). Code which is not strictly
  required will no longer find its way into your programs if you
  link with the updated library.

  NOTE: these changes require that the entire library is rebuilt!
