SYSKEY, TNG freeze, 2.0.x->TNG merge and other thoughts

[Luke Kenneth Casson Leighton]

there is _one_ area that needs to be reviewed in srv_pipe.c, which is now
in srv_pipe_ntlmssp.c in tng, and that is what to do for user
authentication.

no, the "anonymous" code in 2_0 is not correct - it is _not_ the
responsibility of the srv_pipe code to make that decision, it is the
responsibility of the NETLOGON [authentication server] to decide whether
to accept an anonymous user or not.
