    init the binlog_cache (THD::transaction.trans_log).
    I have checked all places where trans_log is used, because as now
    it may not be inited in some cases, we have to be cautious
    (will forward this commit mail to Heikki).
    
    
    sql/handler.cc:
      Do not use the transaction binlog cache if binlog is not open
    sql/sql_class.cc:
      We do not init the transaction binlog cache if binlog is not open.
      This saves 32 KB memory per thread, if --log-bin is not used.
