BUG#28777, WL#4293: SHOW BINLOG EVENTS does not work on relay log

files NOTE: this is the backport to next-mr. SHOW BINLOG EVENTS does not work with relay log files. If issuing "SHOW BINLOG EVENTS IN 'relay-log.000001'" in a non-empty relay log file (relay-log.000001), mysql reports empty set. This patch addresses this issue by extending the SHOW command with RELAYLOG. Events in relay log files can now be inspected by issuing SHOW RELAYLOG EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count].
