From: Ronnie Sahlberg <redacted> Add a `struct ref_storage_be` to represent types of reference stores. In OO notation, this is the class, and will soon hold some class methods (e.g., a factory to create new ref_store instances) and will also serve as the vtable for ref_store instances of that type. As yet, the backends cannot do anything.
