1c456912a1 s4:kdc: Add ‘samba_kdc_entry_pac’ wrapper type
With embedded Heimdal, we can mark a PAC as being trusted (i.e. not
issued by an RODC). This is convenient, as it saves us needing to carry
that information in flags, hoping it isn’t inadvertently lost.

System Heimdal and MIT Kerberos, however, don’t provide a way to mark a
PAC trusted. So we add a new wrapper type, ‘samba_kdc_entry_pac’, that
contains this extra information if ‘krb5_const_pac’ doesn’t contain it
already. As it also stores a pointer to the client entry, the
structure’s lifetime must therefore be carefully managed. Finally, it
keeps track of whether the PAC came across a trust, to know which is
useful in some circumstances.

3358b04a58 s4:kdc: Remove device PAC validation
In the first place, this check was only applicable to the Heimdal KDC,
the MIT KDC not having support for compounded authentication. Secondly,
it was redundant, because _kdc_fast_check_armor_pac() would have already
been called to verify the armor ticket; a second round of validation
achieved nothing. And finally, the check was flawed: it checked only
*explicitly* armored PACs, and so would have done nothing for an armored
*AS‐REQ*.

In short, this check was useless; remove it.
