  Result update.
mysql-test/r/rpl_insert_id.result:
  Test update
mysql-test/t/insert_select.test:
  Check if a partly completed INSERT SELECT (failing because of "Duplicate key"
  after successfully inserting other rows) is written to the binlog if the
  table is not transactional and at least one row has been inserted (bug #491)
mysql-test/t/rpl_insert_id.test:
  Test for bug #490 (INSERT SELECT in auto_increment)
sql/sql_insert.cc:
  - In INSERT ... SELECT, if it fails with error but one row has been inserted and
  the table is not transactional, we must write to the binlog (the slave will stop
  because of the error code in the binlog event, this is normal). bug 491.
  - we must set INSERT_ID before writing to the binlog (bug 490
  accidentally introduced by another dev in 4.0.13).
