new upstream icinga 1.7.0 release - full spec file rework+changes

please note the most important changes:

- moved bindir/idomod.o to libdir/idomod.so (requires config update)
- moved /var/icinga to /var/spool/icinga in icinga.spec (upgrade safe)
- renamed icinga-idoutils rpm to icinga-idoutils-libdbi-mysql|pgsql in
icinga.spec

these changes have been provided in order to make packaging more easy as
well as allow clean upstream packages. the move from /var/icinga to
/var/spool/icinga is made upgrade safe, so on package upgrade
retention.dat and objects.precache will be safely copied if existing.

upcoming icinga-web package will recognize and depend on these changes
as well.

below is the full changelog, for the exact changes on icinga itsself,
please refer to the official upstream Changelog.
