Flags in sql_command_flags[command] are not correctly set for the following 
commands: 

  . SQLCOM_SET_OPTION is missing CF_CAN_GENERATE_ROW_EVENTS; 

  . SQLCOM_BINLOG_BASE64_EVENT is missing CF_CAN_GENERATE_ROW_EVENTS; 

  . SQLCOM_REVOKE_ALL is missing CF_CHANGES_DATA; 

  . SQLCOM_CREATE_FUNCTION is missing CF_AUTO_COMMIT_TRANS;

This may lead to a wrong sequence of events in the binary log. To fix
the problem, we correctly set the flags in sql_command_flags[command].
