ipa-kdb: support KDB DAL version 7.0
krb5-1.16 includes DAL version 7, which changes the signature of
audit_as_req to include local and remote address parameters.

This patch just enables building against the new DAL version and bumps
the minimum in freeipa.spec.in, but doesn't use the new information
for anything.

ipa-kdb: reinit trusted domain data for enterprise principals
While processing enterprise principals the information about trusted domains
might not be up-to-date. With this patch ipadb_reinit_mspac() is called if an
unknown domain is part of the enterprise principal.

e8a7e2e38a ipa-kdb: add pkinit authentication indicator in case of a successful certauth
We automatically add 'otp' and 'radius' authentication indicators when
pre-authentication with OTP or RADIUS did succeed. Do the same for
certauth-based pre-authentication (PKINIT).

A default PKINIT configuration does not add any authentication
indicators unless 'pkinit_indicator = pkinit' is set in kdc.conf.
Unfortunately, modifying kdc.conf automatically is a bit more
complicated than modifying krb5.conf. Given that we have 'otp' and
'radius' authentication indicators also defined in the code not in the
kdc.conf, this change is following an established trend.

SSSD certauth interface does not provide additional information about
which rule(s) succeeded in matching the incoming certificate. Thus,
there is not much information we can automatically provide in the
indicator. It would be good to generate indicators that include some
information from the certmapping rules in future but for now a single
'pkinit' indicator is enough.

593ea7da9a ipa-kdb: support KDB DAL version 6.1
DAL version 6.0 removed support for a callback to free principal.
This broke KDB drivers which had complex e_data structure within
the principal structure. As result, FreeIPA KDB driver was leaking
memory with DAL version 6.0 (krb5 1.15).

DAL version 6.1 added a special callback for freeing e_data structure.
See details at krb5/krb5#596

Restructure KDB driver code to provide this callback in case
we are built against DAL version that supports it. For DAL version
prior to 6.0 use this callback in the free_principal callback to
tidy the code.

Use explicit KDB version dependency in Fedora 26+ via BuildRequires.

With new DAL version, freeipa package will fail to build and
we'll have to add a support for new DAL version explicitly.

per object type that are placed under the object subtrees, DAL driver
needs to search for the policies in the whole tree.

Individual policies referenced by the krbPwdPolicyReference attribute
are always searched by their full DN and with the base scope. However,
when KDC asks a DAL driver to return a password policy by name, we don't
have any specific base to search. The original code did search by the
realm subtree.

a14ebbea89 ipa-kdb: simplify trusted domain parent search
In terms of cross-forest trust parent domain is the root domain of
the forest because we only have trust established with the forest root.

In FreeIPA LDAP store all sub-domains stored in cn=<forest root>,
cn=ad,cn=trusts,... subtree. Thus, a first RDN after cn=ad is the
forest root domain. This allows us to simplify logic of finding
the parent domain.

For complex hierachical forests with more than two levels of
sub-domains, this will still be true because of the forest trust:
as forest trust is established to the forest root domain, any
communication to any sub-domain must traverse forest root domain's
domain controller.

Note that SSSD also generated incorrectly CA paths information
for forests with non-hierarchical tree-roots. In such cases
IPA KDC got confused and mistakenly assumed direct trust to the
non-hierarchical tree-root instead of going through the forest
root domain. See https://fedorahosted.org/sssd/ticket/3103 for
details.
