Introduce a new storage engine API method commit_checkpoint_request(). This is used to replace the fsync() at the end of every storage engine commit with a single fsync() when a binlog is rotated. Binlog rotation is now done during group commit instead of being delayed until unlog(), removing some server stall and avoiding an expensive lock/unlock of LOCK_log inside unlog().
