evgen@moonbone.local 968369906e Bug#19978: INSERT .. ON DUPLICATE erroneously reports some records were ...

updated.

INSERT ... ON DUPLICATE KEY UPDATE reports that a record was updated when
the duplicate key occurs even if the record wasn't actually changed
because the update values are the same as those in the record.

Now the compare_record() function is used to check whether the record was
changed and the update of a record reported only if the record differs
from the original one.
