Description: 

Stub entities were introduces as a counterpart to entity_extract_ids(). An minimal representation of an entity that can be identified by that function.

This idea is no longer compatible with the new classed entities and is therefore removed. The biggest side effect of this change is that EntityFieldQuery::execute() no longer returns stub entites but simple objects with the fixed properties entity_id, revision_id, bundle and entity_type. This does not affect most uses of EntityFieldQuery where all that's required are the entity id's.

When requiring the entity object, entity_load() can be used.
