d03b3faeb8 s4-auth: Use consistant externally-supplied time in auth stack
This makes the time during authentication stay consistent in the KDC
and follows the fake time when we are testing gMSA accounts.  By having
the account expiry follow exactly the same clock as the password expiry
we can hope for less supprises.

eba8799514 auth: Remove .get_challenge (only used for security=server)
With NTLMSSP, for NTLM2 we need to be able to set the effective challenge,
so if we ever did use a module that needed this functionlity, we would
downgrade to just NTLM.

Now that security=server has been removed, we have no such module.

This will make it easier to make the auth subsystem async, as we will
not need to consider making .get_challenge async.

a2ce53c1f5 s4-auth Rework auth subsystem to remove struct auth_serversupplied_info
This changes auth_serversupplied_info into the IDL-defined struct
auth_user_info_dc.  This then in turn contains a struct
auth_user_info, which is the only part of the structure that is
mainted into the struct session_info.

The idea here is to avoid keeping the incomplete results of the
authentication (such as session keys, lists of SID memberships etc) in
a namespace where it may be confused for the finalised results.

This makes everything reference a server_info->sids list, which is now
a struct dom_sid *, not a struct dom_sid **.  This is in keeping with
the other sid lists in the security_token etc.

In the process, I also tidy up the talloc tree (move more structures
under their logical parents) and check for some possible overflows in
situations with a pathological number of sids.
