[HECnet] New bridge version

[Oleg Safiullin]

One more diff: http://pdp-11.nsk.ru/~form/files/bridge/bridge-tap.patch

It contains my previous path for OpenBSD and adds support for OpenBSD/Linux `tun' interface, so you
can use it for SimH:

bridge.conf:
------------
[bridge]
tunnel @tun0
------------

pdp11.ini:
------------
att xq tun0
------------

Ok. After some whacky hacking to merge what Hans sent me, I've uploaded a new version at http://www.update.uu.se/~bqt/hecnet

o Update for OpenBSD to avoid loops.
o Drop MAX() definition - it isn't used
