This is a become_root user callout that I have never seen in use in
more than 20 years of Samba. Why disable now? In the next commit I
need to make a change to initializing the registry values for
services, the svcctl service won't be able to do registry transactions
anymore. I'm not sure that going without transactions is 100% safe in
all failure cases, so I decided to propose disabling the problematic
code that might lead to security issues.
One fix might be to add a lot more validation code to
_svcctl_OpenServiceW() to see whether the registry values underlying
the service are sane.
Yes, this is technical debt, but I would question that starting unix
daemons via DCERPC used at all out there.

A customer's syslog was filled with
_svcctl_OpenServiceW: Failed to get a valid security descriptor
messages. This improves the messages to give info about which service failed
with which error code. Also, it makes OpenServiceW fail with the same error
message Windows fails with for unknown services.

This patch finally has the same structure being used to describe the
authorization data of a user across the whole codebase.
This will allow of our session handling to be accomplished with common code.

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.

The "is_valid_policy_handle" in the exit path reads uninitialized data
Lets see if this fixes Coverity ID 2172 which complains about h being
dereferenced in the dcerpc_winreg_CloseKey.

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).

This is a bigger commit. It moves the relevant function to
svc_winreg_glue. We need to use them in the same commit else we have
problems with prototypes in proto.h.

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

The all UPPER case typedef is no longer the preferred Samba style
and this makes it easier to see that this is the IDL-derivied structure
