As of iOS 10, ASL is deprecated and replaced with os_log. ASL calls continue to result in logging but as of iOS 10.3, only ASL_LOG_NOTICE level and above are logged. This change partially reverts 2937f06, adding back stdout and stderr redirection, which resulted in loss of some direct writes to stdout that were necessary for debugging. This change replaces the direct use of syslog with ASL on iOS, which Apple has stated will continue to log on iOS >= 10. This eliminates the need for the previous fwd-declaration of syslog.
