This patch brings in the removal of debug logging altogether, instead we bring in the functionality of being able to trace the errors properly pointing back to the origination of the problem. To enable tracing you need to enable "MINIO_TRACE" set to "1" or "true" environment variable which would print back traces whenever there is an error which is unhandled or at the handler layer. By default this tracing is turned off and only user level logging is provided.
