      - Fix for BUG#1858 "SQL-Thread stops working when using optimize table": · eb008b18
      unknown authored
      we change THD::system_thread from a 'bool' to a bitmap to be able to
      distinguish between delayed-insert threads and slave threads.
      - Fix for BUG#1701 "Update from multiple tables" (one line in sql_parse.cc,
      plus a new test rpl_multi_update.test). That's just adding an initialization.
      
      
      sql/repl_failsafe.cc:
        comment to warn about this unused code
      sql/slave.cc:
        Now thd->system_thread is a bitmap, not a bool.
      sql/sql_class.h:
        'bool' for THD::system_thread is not accurate enough; sometimes we need
        to distinguish between delayed-insert threads and slave threads;
        so changing THD::system_thread to a bitmap (uint).
      sql/sql_insert.cc:
        thd.system_thread is now a bitmap
      sql/sql_parse.cc:
        We need to initialize thd->lex.select_lex.options in mysql_init_query();
        it's already initialized in dispatch_command() but replication calls
        mysql_parse() directly, thus bypassing dispatch_command().
        Not initing it here leads to a query influencing the next query,
        in the slave SQL thread.
        The initialization in dispatch_command() must be kept as this
        command uses the variable in tests, even when the command was not a
        query (i.e. when mysql_init_query() was not called).
