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.
