[Kexi] Buffered cursors for sqlite3

[Jaroslaw Staniek]

Adam,
Turns out that it's safer to say: buferred cursors does not work at
all for sqlite 3. The implementation just does not crash, but only
worked for sqlite 2.

It's all a TODO work.

If needed, you can buffer on your own by reading into QList or QVector
of records (as we do in KexiTableViewData).
libpredicate will deliver this feature, since we have more and more
use cases for this.

I am not even sure mysql or pgsql implementation can even work correctly.
