r5402: a initial attempt at a IDL definition of the WINS replication protocol

on tcp port 42. This is enough to reasonably decode (with ndrdump) all
the packets I have seen on the wire. It will need some fine tuning
once I understand the protocol a bit more.
(This used to be commit 3f90bc132139815c23c7322d3d47268d92ba00ac)
