* Cache stores has a new feature DEREFERENCES_OBJECTS.
  This allows the cache loader to decide if it needs to handle dereferencing or whether the data
  coming directly to it has already had references resolved.
  - see supports_dereferencing_objects in store.php.
* The following methods have been finally deprecated and should no longer be used.
  - cache_definition::should_be_persistent()
  - cache_definition::get_persistent_max_size()
  - cache::is_using_persist_cache()
  - cache::is_in_persist_cache()
  - cache::get_from_persist_cache()
  - cache::set_in_persist_cache()
  - cache::delete_from_persist_cache()
  - cache_store::cleanup()
* cachestore_dummy::cleanup() has been deprecated.
* cachestore_dummy::instance_deleted() implemented in lieu of cachestore_dummy::cleanup().
* Added cache_store::unit_test_configuration() to calculate unit testing configuration.
* Remove cache_store:initialise_unit_test_instance() as it is incompatible with cache_helper purge functions.
