- mysqldump generated output that set OLD_SQL_MODE twice, to different values
    (for triggers), or not at all (for routines) in some cases.


client/mysqldump.c:
  Only save SQL_MODE in dump_triggers if in --compact mode. Otherwise,
  it's already been saved in write_header(). Likewise for dumpe_routines,
  where it was never saved.
mysql-test/r/mysqldump.result:
  mysqldump output has subtly changed. Adjust test-results. This also shows
  OLD_SQL_MODE is always set exactly once now
