use fdatasync() for redo log where appropriate

    Details

      Description

      Redo log files are fixed size files. They're almost never renamed. So, metadata is not changed. For such cases we can use `fdatasync()` which doesn't flush metadata, like `fsync()` does. That should bring use some performance.
