With the new option, the library can be compiled with the entire logging infrastructure disabled. The public api remains unchanged, but the internal logging functions will have no effect anymore. In practice the overhead of the logging functions should be quite small, and disabling the logging at runtime might be more convenient. Especially because troubleshooting will become much harder without any logging.
