Peter Wemm 472fe5e4db Dont allow directories to be link()ed or unlink()ed, even for root ...

(returns EPERM always, the errno is specified by POSIX).

If you really have a desperate need to link or unlink a directory, you
can use fsdb. :-)

This should stop any chance of ftpd, rdist, "rm -rf", etc from
bugging out and damaging the filesystem structure or loosing races
with malicious users.
