removed mechanism that created actual files NETLOGON, lsarpc and the like,
which are pipes on the IPC$ connection. created mechanism to record pipe names in a separate pipes_struct. it is planned to expand this, to return sensible things like interface structures, and policy handles (RPC_IFACE and LSA_POL_HND). and the like. (This used to be commit 33cce5fac0e2f818a19a6c4e6a797ef44f3b5c75)
