- Separate template definition from template declaration

- Explicitly instantiate Singleton templates to be exported from libbackend.so
- Install only header files that are backend interfaces to be exposed to the user
- Don't use full path for including templates in header files
- Instantiate a couple of smart_ptr templates to have their symbols exported outside the DSO. This happens in history.cc. FIXME: the interface for History will definitely need to be reworked, and the two smart_ptr explicit instantiations removed.
- Change SWIG exported interface to make use of Schedulable instead of (Dynamic|Static)Schedulable
- Fix provided policies to make use of the new interface
- TODO: limit the use of smart_ptrs.
