1. sync_binlog=1 is needed to ensure that on flush binlog is available on disk. 2. Insert on 'connection master2' should wait for 'master1_ready' from 'connection master1'. Added sync_binlog=1 to all tests that got added as part of MDEV-21117 fix @mysql-test/suite/binlog/t/binlog_truncate_multi_log_unsafe.test @mysql-test/suite/binlog/t/binlog_truncate_multi_engine.test @mysql-test/suite/binlog/t/binlog_truncate_active_log.test @mysql-test/suite/binlog/t/binlog_truncate_multi_log.test
