Subject: [PATCH 5/9] Krb5: improve [dbmodules] and includes (#630)
* Krb5: fix/revamp parsing of [dbmodules] subsection
The [dbmodules] subsection so far was parsed much like the [dbdefaults]
one, and thus it did not handle realms.
Revamp it a bit to handle realms, and specify the only keyword not in
realm subsections.
* Krb5: allow include/includedir directives everywhere
MIT Kerberos allows this, so do not restrict them only before any other
section.
