[cliffs] update

[Luke Kenneth Casson Leighton]

two steps forward, one step back.  or is it the other way round?

ok, just fixed up silly linked-list bug.

 i now have, i believe, the semantics for files-closing, correct, namely
[and if anyone know therwise please let me know!] that when you cloe a
treecon, you close al files in that tid but _also, when you close a
session  (SMBulogoff disconnects a vuid), you _also_ close the files
opened by that user.  

so what i do is i maintain a separate single-linked-list on a per-session
basis _as well_ as a list of files in a tcon.

... i just realised that this list is not updated if you do a tree
disconnect.  oops.  will fix that next.

am still thinking about oplocks.

will move on to auth, soon, and will start on DCE/RPC code for
net_r_samlogon auto-generation then.
