048de3da01 s4:libnet: Pass SDB_F_ADMIN_DATA flag through to samba_kdc_message2entry()
This will allow us to specify whether to specify this flag for a keytab
export.

6ecc607ede s4:kdc: split out samba_kdc_fill_trust_keys() helper
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.

Review with: git show -p --patience

d1efc396de s4:kdc: let samba_kdc_trust_message2entry() ignore KRB5_PROG_ETYPE_NOSUPP
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.
