If an engine comes up explicitely, it must also come down explicitely
In apps/apps.c, one can set up an engine with setup_engine(). However, we freed the structural reference immediately, which means that for engines that don't already have a structural reference somewhere else (because it's a built in engine), we end up returning an invalid reference. Instead, the function release_engine() is added, and called at the end of the routines that call setup_engine().
