[HECnet] Cisco DECnet routers and NML

[Paul Koning]

The mapper uses "show exec char", "show act node status", and "show act circ status".  For exec char, all it needs is name and type.  For act node, it wants node id/name, plus the circuit and type if the node is adjacent, though it can do without since some other implementations don't implement that.  For act circ it needs the node id/name.

It can even be somewhat buggy; for example I have a workaround that skips some of the requests when talking to an endnode because of a RSTS bug.  It does have to be minimally sane: the Linux NICE server is so utterly broken that it might as well not exist at all.
