I didn't get this right the last time....

When an NCP reaches TLF, *ONLY* datalink_Close() links that are
in DATALINK_OPEN.

When the last link reaches TLD, DOWN all NCPs (as we used to in the
links TLF (which was the wrong place anyway)), as the NCPs aren't
now going to datalink_Close() us unexpectedly, we get to continue
doing what we were told to do in the first place.

The result:  When we lose a link, the IPCP layer goes down and
we actually call the stuff in ppp.linkdown !
