New SMB marshalling logic

[Ron <ron () skullsecurity net>]

Hi all,

I've spent the past couple weeks writing new marshalling logic for my
SMB code, and fixing bugs in it that Brandon found. At this point, it's
finished and stable, but I wanted to get comments on it before merging
it with the main branch. The code is here:
svn://svn.insecure.org/nmap-exp/ron/smb-marshalling

The primary differences are in msrpc.lua and msrpctypes.lua (which is a
new file). I broke off msrpctypes because it's 4000 lines. Standard
implementations use a separate file for each type of function (SAMR,
LSA, SRVSVC, etc), but I figured that'd be too much sprawl, and that one
file was enough.

The biggest advantage to the updated marshalling code is that it
properly understands pointers, structures, and arrays, so if it's
hitting a system that implements it differently from Windows, it'll
still work. Also, because I've implemented a lot of the base types
(nttime, gid, sid, strings, etc), adding new function calls is a bit
easier.

So anyway, take a look and let me know if you have any suggestions. If
not, I'll call it stable, dump it into the main branch, and start
working on some cool new features. :)

Ron
