  Fixed bug #29788.
  After dumping triggers mysqldump copied 
  the value of the OLD_SQL_MODE variable to the SQL_MODE
  variable. If the --compact option of the mysqldump was
  not set the OLD_SQL_MODE variable had the value
  of the uninitialized SQL_MODE variable. So
  usually the NO_AUTO_VALUE_ON_ZERO option of the
  SQL_MODE variable was discarded.
  
  This fix is for non-"--compact" mode of the mysqldump,
  because mysqldump --compact never set SQL_MODE to the
  value of NO_AUTO_VALUE_ON_ZERO.
  
  The dump_triggers_for_table function has been modified
  to restore previous value of the SQL_MODE variable after
  dumping triggers using the SAVE_SQL_MODE temporary
  variable.
