The MIT KDC has a fallback to a consistent time per fetch call, and
both implementations then follow the time in each 'struct
samba_kdc_entry'.

This simplifies the logic in samba_kdc_trust_message2entry(),
is very similar to our samba_kdc_fill_user_keys() helper
and will make it trivial to provide the previous keys
in entry->old_keys in the next commit.

We already handle it in samba_kdc_fill_user_keys() mostly for DES keys,
but other encryption types might be from kerberos libraries in future.
And things like FIPS mode may also alter the runtime behaviour.

We need to allow a samdb to be passed from the python to support

The gMSA passwords will not use this code, but we need to be

We only ever use the principal comparison functions to check equality.
Having these functions only handle equality simplifies their
implementation and makes them a bit easier to use.

The existing implementation did not differentiate between the case where
the relevant component was not present, and that where talloc_strndup()
failed. To correct this situation, put the result into an out parameter
on success and return an error on failure.

This means that expressions like ‘Device_Member_of(WD)’ will now work,
as they should.
It *also* means that expressions like ‘Device_Member_of(NU)’ will work,
even though they shouldn’t. This is because we consider SID_NT_NETWORK
to be a default group.
Our new behaviour may be wrong, but at least it’s now consistent with
the behaviour of user‐relative expressions like ‘Member_of(WD)’ and
‘Member_of(NU)’.
