This allows us not the put all of these elements into the auth3_session_info
if they are only used as inputs to these functions.

The long term authorization state needs only the final, negotiated
session key, and not the original LM key that may possibly have been
an input.
The special case of the guest account simply needs both values filled
back in with the zeros to avoid changing behaviour in the cached
server_info.

This brings this structure one step closer to the struct auth_session_info.
A few SMB_ASSERT calls are added in some key places to ensure that
this pointer is initialised, to make tracing any bugs here easier in
future.
NOTE: Many of the users of this structure should be reviewed, as unix
and NT access checks are mixed in a way that should just be done using
the NT ACL. This patch has not changed this behaviour however.

This seperation between the structure used inside the auth modules and
in the wider codebase allows for a gradual migration from struct
auth_serversupplied_info -> struct auth_session_info (from auth.idl)
The idea here is that we keep a clear seperation between the structure
before and after the local groups, local user lookup and the session
key modifications have been processed, as the lack of this seperation
has caused issues in the past.

This will allow a gradual conversion of the required elements from the
current struct auth_serversupplied_info.
This commit adds the structure definition and some helper functions to
copy between the two structures.
At this stage these structures and functions are IDENTICAL to the
existing code, and so show the past history of that code. The plan is
to slowly modify them over the course of the patch series, so that the
changes being made a clear.
By using a seperate structure to auth_serversupplied_info we can
remove elements that are not needed after the authentication, and we
can choose a layout that best reflects the needs of runtime users,
rather than the internals of the authentication subsystem.
By eventually using the auth_session_info from auth.idl, we will gain
a single session authorization structure across the whole codebase,
allowing more code to be shared, and a much more transparent process
for forwarding authorization credentials over the named pipe proxy.

The implementation of copy_serverinfo(), used to copy server_info into
session_info never copied the nss_token variable, and so
17d8f0ad30847bb940f645ee1817d782ddaaee74 introduced this regression.

I've got a backtrace where this must have failed, but it is not clear why. If
this fails, we should really complain because we can't start up.

There is no reason this can't be a normal constant string in the
loadparm system, now that we have lp_set_cmdline() to handle overrides
correctly.

Andreas Schneider <asn@samba.org> correctly points out that this input
parameter should now be const, and that found a bug where I used then
used it incorrectly as a talloc context.

Before a auth_serversupplied_info struct can be used for
authorization, the local groups and privileges must be calculated.
create_local_token() now copies the server_info, and then sets the
calulated token and unix groups.
Soon, it will also transform the result into an expanded struct
auth_session_info. Until then, the variable name (server_info vs
session_info provides a clue to the developer about what information
has been entered in the structure).
By moving the calls to create_local_token within the codebase, we
remove duplication, and ensure that the session key (where modified)
is consistently copied into the new structure.
Andrew Bartlett
These variables, of type struct auth_serversupplied_info were poorly
named when added into 2001, and in good consistant practice, this has
extended all over the codebase in the years since.
The structure is also not ideal for it's current purpose. Originally
intended to convey the results of the authentication modules, it
really describes all the essential attributes of a session. This
rename will reduce the volume of a future patch to replaced these with
a struct auth_session_info, with auth_serversupplied_info confined to
the lower levels of the auth subsystem, and then eliminated.
(The new structure will be the output of create_local_token(), and the
change in struct definition will ensure that this is always run, populating
local groups and privileges).

In these cases, the server_info was not stolen onto a long term memory
context, and so remained on the NULL context where it was created.

This will allow the auth_serversupplied_info struct to be migrated
to auth_session_info easier.

through Get_Pwnam_alloc(), which is the correct wrapper function. We were using
it *some* of the time anyway, so this just makes us properly consistent.

This will reduce the noise from merges of the rest of the
libcli/security code, without this commit changing what code
is actually used.
This includes (along with other security headers) dom_sid.h and
security_token.h

Without this, all security descriptor checks for the winreg spoolss backend fail
and make our spoolss system in its current shape basically unusable.
