Jason Dana 2ff279e21e policycoreutils: semanage: update to new source policy infrastructure 
- Remove version references
- Use new methods for enabling/disabling modules
- Add support to set priority when adding/removing modules
- Modify module --list output to include priority and language extension
- Update permissiveRecords call to support cil policy
