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

        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.
