If the structural objectclass is allowed to change, then the restrictions
locking an object to remaining a user or computer will not be enforcable.
Likewise other LDAP inheritance rules, which allow only certain
child objects can be bypassed, which can in turn allow creation of
(unprivileged) users where only DNS objects were expected.

Looking up the DB twice is subject to a race and is a poor
use of resources, so instead just pass in the record we
already got when trying to confirm that the server in
S4U2Self is the same as the requesting client.
The client record has already been bound to the the
original client by the SID check in the PAC.
Likewise by looking up server only once we ensure
that the keys looked up originally are in the record
we confirm the SID for here.

These common routines will assist the KDC to do the same access
checking as the RPC servers need to do regarding which accounts
a RODC can act with regard to.

In particular the objectGUID is no longer used, and in the NETLOGON case
the special case for msDS-KrbTgtLink does not apply.

This shares the lookup of the tokenGroups attribute.
There will be a new caller that does not want to do this step,
so this is a wrapper of samdb_confirm_rodc_allowed_to_repl_to_sid_list()
rather than part of it

While these checks were not in the NETLOGON case, there is no sense where
an RODC should be resetting a bad password count on either a
UF_INTERDOMAIN_TRUST_ACCOUNT nor a RODC krbtgt account.

This will allow the creation of a common helper routine that
takes the token SID list (from tokenGroups or struct auth_user_info_dc)
and returns the allowed/denied result.

This is instead of an array of struct dom_sid *.
The reason is that auth_user_info_dc has an array of struct dom_sid
(the user token) and for checking if an RODC should be allowed
to print a particular ticket, we want to reuse that a rather
then reconstruct it via tokenGroups.
This also avoids a lot of memory allocation.

If multiple calls to get_tgt() or get_service_ticket() specify different
expected parameters, we want to perform the request again so that the
checking can be performed, rather than reusing a previously obtained
ticket and potentially skipping checks.
It should be fine to cache tickets with the same expected parameters, as
tickets that fail to be obtained will not be stored in the cache, so the
checking will happen for every call.
