Slave thread is always in an auto-commit state: remove unnecessary tests when we flush master info

  Initing a mutex with MY_MUTEX_INIT_FAST may relieve thread thrashing on Linux

  Merge 3.23.52

  Use current_thd to check if a transaction is done by a slave thread

  Add syntax SET NO_FOREIGN_KEY_CHECKS=1 and SET RELAXED_UNIQUE_CHECKS=1

  Add option innodb_flush_log_at_trx_commit=2 which means we always write the log to file at commit, but only do fsync about once per second

  Merge 3.23.52

  Add BEGIN andd COMMIT around transactions in the binlog

  Do not flush the position to master.info file if we have a transaction open
