Previously, if any fields in the supplied record could not be matched
with a column in the target table, dataChanged() was supressed for all
columns for OnManualSubmit. This is not good because it prevents other
views from noticing the fields that *do* change.
It's simplest and probably more efficient just to emit
dataChanged() once for the whole row. Fewer signals need to be
processed and in typical cases much or all of the row is likely to
be changed anyway.

In an apparent attempt to be economical with emitting dataChanged()
and submitting SQL to the databse, setRecord() compares each field
value of the record with the old value, taking action only when
a difference is detected. Several complaints against this code are:
-The comparision does not work on float type.
-It is really up to the application and database to decide this. The
model should make few assumptions. The application has the option to
omit fields from the record that should be ignored.
-The current behavior seems to assume that the "old" values are the
current state of the database, but the database may have changed since
the model was last refreshed.
-The code compares the value from record(), which probably
corresponds to the EditRole, with the DisplayRole value from data().

Use submit() instead of calling updatRowInTable(). The effect is
exactly the same. Submit() invokes submitAll() which invokes
updateRowInTable(). The cache is purged and select() is called only
on success.

Emit dataChanged() before a possible new select instead of after.
The select reinserts all the rows, emitting signals for that, so
there isn't any point to dataChanged() afterwards.

Affects setData() and setRecord().
Previously dataChanged() was suppressed when editing an inserted
record, except for OnManualSubmit. The motivation was probably to
allow setData() to be used while handling primeInsert().
Suppressing dataChanged() is not a good idea since views other than
the one which made the change will not know of the change.
It is a terrible idea to call setData() or setRecord() while
handling primeInsert(), so this is now expressly forbidden.
setData() and setRecord() now do nothing and return false if called
while rows are being inserted.

Even though ModifiedRow is not part of the public API, guarding its
data helps make clear the intended patterns of use.
"op" and "primaryValues" are read-only after construction.
setValue() encourages maintainers to let ModifiedRow manage the
"generated" flags of the record.
The primeInsert() signal still exposes the actual record, including
the "generated" flags, which is the justification for recRef().

-Do not use setData()
We're using ModifiedRow now so it makes sense to buffer the changes
and submit the row at once. This improves readability and
encourages further haromonization of the editing strategies.
-No longer need temporary change to OnRowChange
Previously, the strategy was temporarily changed from OnFieldChange
to OnRowChange in order to obtain the desired behavior from setData().
Now, since we don't use setData(), we can program the desired behavior
here and don't need this trick.
