Updated the engine load functionality
- engine_load/3/4 can be called multiple times for same engine if it allows it (eg doesn't contain global data) - ensure_engine_loaded/2/3 is new functions that guarantees that the engine is just loaded once by adding it to OpenSSL internal engine list and check that before loading. - ensure_engine_unloaded/1/2 is new functions that is used to unload engines loaded with ensure_engine_loaded (remove it from OpenSSL internal engine list and then unload). - new utility functions engine_by_id/1, engine_add/1, engine_remove/1, engine_get_id/1 and engine_get_name/1
