- reorganize specfile:
* patches back to -p1, much easier to handle
* create pdnsd.service from single template for SLES12 (no
hardening) and newer (hardening), do not maintain 2 files
* put licences back into main package, only large doc into
-doc subpackage
- add patch pdnsd-fix-preproc-errors.patch to make compiletime
default query selection actually work
- remove cache file creation from package, the daemon creates this
on first exit (see discussion in boo#1216277)
- add pdnsd-nodaemon-logfix.patch to remove the useless additional
timestamp from journal logs
