I don't want to change the meaning of already existing configuration
variables. Also, I still think it is better to put a limit to the size
of the buffer, and drop PACKETs when the buffer is larger than that
limit. Late packets rarely do any good anyway, best to get rid of them.

It was used in the past (up to and including 1.0pre2), but not for
anything useful. Now it might be useful to debug tinc (you can see it in
the logs if you send a SIGUSR1 to a running tincd).
