default value for sync_binlog should be the safer value 1 instead of 0

Details

    Description

      The default variable for sync_binlog is 0 for MariaDB, where Oracle changed it to 1 starting with 5.7.7. I think we should also change the default to 1, as running a master with sync_binlog=0 is risky - any crash of server or mysqld will create inconsistent slaves 99% of the time.
