This changes ensures that smbd always adds BUILTIN\Guests to the guest token
which is required for guest authentication.
Currently the guest token depends on the on-disk configured group mappings. If
there's an existing group mapping for BUILTIN\Guests, but LOCALSAM\Guest is not
a member, the final guest token won't contain BUILTIN\Guests.
For SMB2 the flag SMB2_SESSION_FLAG_IS_GUEST will not be set in the final SMB2
SESSION_SETUP response, because smbd sets it based on the token containing the
BUILTIN\Guests SID S-1-5-32-546.
At the same time, the packet is not signed which causes Windows clients and
smbclient to reject the unsigned SMB2 SESSION_SETUP response.

This is not a general purpose profiling solution, but these JSON logs are already being
generated and stored, so this is worth adding.
Some administrators are very keen to know how long authentication
takes, particularly due to long replication transactions in other
processes.
This complements a similar patch set to log the transaction duration.

It's important to have them separated from make_{server,session}_info_guest(),
because there's a fundamental difference between anonymous (the client requested
no authentication) and guest (the server lies about the authentication failure).
When it's really an anonymous connection, we should reflect that in the
resulting session info.
This should fix a problem where Windows 10 tries to join
a Samba hosted NT4 domain and has SMB2/3 enabled.
We no longer return SMB_SETUP_GUEST or SMB2_SESSION_FLAG_IS_GUEST
for true anonymous connections.
The commit message from a few commit before shows the resulting
auth_session_info change.

These functions make it possible to construct a full auth_session_info
from the information available from an auth_user_info_dc structure.
This has all the logic from create_local_token() that is used
to transform a auth_serversupplied_info to a full auth_session_info.
In order to workarround the restriction that auth_user_info_dc
doesn't contain hints for the unix token/name, we use
the special S-1-5-88 (Unix_NFS) sids:
- S-1-5-88-1-Y gives the uid=Y
- S-1-5-88-2-Y gives the gid=Y
- S-1-5-88-3-Y gives flags=Y AUTH3_UNIX_HINT_*
The currently implemented flags are:
- AUTH3_UNIX_HINT_QUALIFIED_NAME
unix_name = DOMAIN+ACCOUNT
- AUTH3_UNIX_HINT_ISLOLATED_NAME
unix_name = ACCOUNT
- AUTH3_UNIX_HINT_DONT_TRANSLATE_FROM_SIDS
Don't translate the nt token SIDS into uid/gids
using sid mapping.
- AUTH3_UNIX_HINT_DONT_TRANSLATE_TO_SIDS
Don't translate the unix token uid/gids to S-1-22-X-Y SIDS
- AUTH3_UNIX_HINT_DONT_EXPAND_UNIX_GROUPS
The unix token won't get expanded gid values
from getgroups_unix_user()
By using the hints it is possible to keep the current logic
where an authentication backend provides uid/gid values and
the unix name.
Note the S-1-5-88-* SIDS never appear in the final security_token.

We should add Builtin_Guests depending on the current token
not based on 'is_guest'. Even authenticated users can be member
a guest related group and therefore get Builtin_Guests.
Sadly we still need to use 'is_guest' within create_local_nt_token()
as we only have S-1-22-* SIDs there and still need to
add Builtin_Guests.
