The auth_authsupplied_info typedef is now just a plain struct - auth_context,
but it has been modified to contain the function pointers to the rest
of the auth subsystem's components.
(Who needs non-static functions anyway?)
In working all this mess out, I fixed a number of memory leaks and moved the
entire auth subsystem over to talloc().
Note that the TALLOC_CTX attached to the auth_context can be rather long-lived,
it is provided for things that are intended to live as long. (The
global_negprot_auth_context lasts the whole life of the smbd).
I've also adjusted a few things in auth_domain.c, mainly passing the domain as
a paramater to a few functions instead of looking up lp_workgroup(). I'm
hopign to make this entire thing a bit more trusted domains (as PDC) freindly
in the near future.
Other than that, I moved a bit of the code around, hence the rather messy diff.
