  Log:
  SVN rev 213215 on 2010-09-27 17:47:09Z by jh
  
  Add reference counting for devfs paths containing user created symbolic
  links. The reference counting is needed to be able to determine if a
  specific devfs path exists. For true device file paths we can traverse
  the cdevp_list but a separate directory list is needed for user created
  symbolic links.
  
  Add a new directory entry flag DE_USER to mark entries which should
  unreference their parent directory on deletion.
  
  A new function to traverse cdevp_list and the directory list will be
  introduced in a separate commit.
