           Bugfix: dangling pointer in vstring_sprintf_prepend().
           File: util/vstring.c.

   20080814

           Security: some systems have changed their link() semantics,
           and will hardlink a symlink, contrary to POSIX and XPG4.
           Sebastian Krahmer, SuSE. File: util/safe_open.c.

           The solution introduces the following incompatible change:
           when the target of mail delivery is a symlink, the parent
           directory of that symlink must now be writable by root only
           (in addition to the already existing requirement that the
           symlink itself is owned by root).  This change will break
           legitimate configurations that deliver mail to a symbolic
           link in a directory with less restrictive permissions.
