For OnFieldChange and OnRowChange, we don't want more than one row in
the cache with uncommitted changes. This could happen if deletion in
the database fails while other changes are pending.
Chosen solution is to return false if other rows have pending changes.
Also, we only allow 1 row removed at a time.
Updated test, changes and documentation.

The model can never do a good job of knowing when user moves to a
new row in the view. Faking it by detecting when another row
is changed was not a good solution because it cannot detect
when the last edited row is left.
Either the view should automatically submit when the user leaves
a row or the application should provide a way to submit.
This change made it possible to reuse the logic of flags() in
setData().

For OnFieldChange and OnRowChange, inserting rows should not be

For OnFieldChange and OnRowChange, before submitting new changes,
setData() and setRecord() attempt to submit pending changes and
revert them upon failure. However, they fail to consider that
reverting pending insertions removes rows from the model. As a
result, the new change can be applied to a row higher than intended.
One possible solution would be to adjust the targetted index for the
removed rows, so that the intended row is affected by the new change.
But this still causes the strange editing experience as rows jump
up just as they are being edited.
It does not seem right in the first place for the model to initiate
reverting changes. It should be up to the application to decide what
to do when data cannot be committed. In particular, setData() and
setRecord() should not have the side effect of reverting already
pending changes.
The chosen solution is simply to refuse new changes that don't make
sense for the edit strategy. For OnFieldChange, flag() will
indicate read-only when editing is blocked by a pending change.
Since setData() and setRecord() submit data immediately for
OnFieldChange, it no longer makes sense to resubmit changes
automatically before a new change.
For OnRowChange, setData() keeps the behavior of automatically
submitting a pending row before starting on a new row. This is
historical behavior and is probably motivated by the fact that
QTableView does not automatically call submit() when editing leaves a
row. The obvious shortcoming of this is that the last row to be edited
will not be submitted automatically. It also prevents us from flagging
rows other than the pending row as read-only.
For OnRowChange, setRecord(), being row-oriented by nature, should
submit the change immediately rather than waiting for the next call
to setRecord(). This makes setRecord() consistent with insertRecord().

Once an insert has been submitted, the cached record behaves like an
update. For row bookkeeping, we still have to remember that it was
originally inserted and is not in the query rows.
Between submitting a delete and selecting, we remove the values
from the deleted record. This causes a blank row to be displayed.
Read-only flag is set for cells in deleted row.
Reverting between submit and select means going back to the last
submitted values.
When removing rows, it's better to process from highest row numbers
to lowest. This avoids complications with higher rows shifting down
when lower rows are removed.

The purpose of the hack was to fool QSqlQueryModel into signaling the
removal of extra rows via rowsRemoved(). The extra rows are the
inserted rows generated by QSqlTableModel.
While it is important to signal the removal of all the rows before
requerying after committing changes, there is a cleaner way. The
table model should remove its rows before the query model removes its
rows.
Iterating backwards avoids having to decrement row numbers above ones
being removed.
Expected test results have been adjusted for these changes.

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().
