- sles12 submission:
* mod_auth_kerb.apache22.patch -> mod_auth_kerb.apache22+.patch
make apache 2.2 modifications unconditional, as they are
required by apache 2.4, too.
This immediately means that compiling this package against
apache 2.0 would not work.
* rework mod_auth_kerb-5.4-apache24.patch into
mod_auth_kerb-api_changes_apache24.patch: adaption to apache
2.4 API, in particular logging and remote IP reference struct
members.

- preparation of the package for submission against sle11-sp1,
review of source and patches/changes, compilation warnings,
licence and packaging. This is (FATE#313165) (ECO-FATE#313165)
and [bnc#771265].
