Giuseppe D'Angelo a057b026b8 QSqlDatabase: remove a pointless const_cast
The history of that one line of code is... interesting, to say the
least. `defaultConnection` was originally declared as `char *`, which
happened to work on older MSVC versions. Then it gained a workaround for
other platforms by conditionally marking it const, with a const_cast to
keep the code working on MSVC. Now it is unconditionally declared as a
const char *, but the const_cast is still there. Get rid of it.

Ivan Solovev c4fabe37b9 Remove QSqlTableModel::setQuery(const QSqlQuery &)

We can't completely remove it, so we just add it to removed_api.cpp

By removing the setQuery() method in the QSqlTableModel class, we
open up name lookup to the base class, where the const ref overload
was already deprecated in 14f9f00fdb,
and the proper replacements were provided.

[ChangeLog][QtSql][QSqlTableModel] The setQuery(const QSqlQuery &)
method is removed, because QSqlQuery cannot be copied correctly.

instead. They allow passing of QSqlQuery by rvalue ref, or creation
of the query by specifying query string and database object.

Edward Welbourne dcd87049bb Treat invalid Q(Date)?Time as null when used as an SQL value
In Qt 5, QVariant::isNull() was true when the contained object had an
isNull() that was true; this is no longer true in Qt 6, so we now have
QSqlResultPrivate::isVariantNull() to test is-or-contains
null. However, for date-times, QSqlDriver::formatValue() treats
invalid QDateTime as NULL, since it needs its toString(Qt::ISODate),
which will be empty if invalid. As QDateTime's isValid() is more
stringent than its !isNull(), this can lead to one that's neither
valid nor null, such as QDateTime(QDate(), QTime(0, 0)), producing an
invalid entry in a database.

Do the same for QTime, as its isValid() is more stringent than
!isNull(), and its toString() likewise returns empty on invalid
(although it's not clear it's possible to construct one that's neither
valid nor null). For QDate valid and null are simply complementary.

[ChangeLog][QSql] Handling of QDateTime and QTime values passed to SQL
now consistently treats invalid as null. Some values of these types
are neither valid nor null, which could lead to invalid data being
given to the SQL database. Invalid values are now treated as null to
prevent this.

Volker Hilsheimer 999d856bc8 Adapt SQL drivers to Qt 6 change of QVariant::isNull
In Qt 5, QVariant::isNull returned true if either the variant didn't
contain a value, or if the value was of a nullable type where the type's
isNull member function returned true.

In Qt 6, QVariant::isNull only returns true for variants that don't
contain a value; if the value contained is e.g. a null-QString or
QDateTime, then QVariant::isNull  returns false.

This change requires a follow up in the SQL drivers, which must
still treat null-values the same as null-variants, lest they write data
into the data base.

Add a static helper to QSqlResultPrivate that implements isNull-checking
of variants that contain a nullable type relevant for Sql, and add a
test case to the QSqlQuery test that exercises that code.

Giuseppe D'Angelo 14f9f00fdb QSqlQuery: make it a move only type
QSqlQuery is a broken value class. Copying one object would mean
copying database state (the result set, the cursor position, etc.)
which isn't generally available for all database drivers.
For that reason, the current implementation does not honor value
semantics -- modifying a QSqlQuery object has visible side effects
on its existing copies (!).

The correct solution is to accept that QSqlQuery is a move only
type, not a value type. Add move semantics to it, and deprecate
its copies.

(We can't just *remove* copies in Qt 6 due to SC/BC constraints).

[ChangeLog][QtSql][QSqlQuery] QSqlQuery copy operations have
been deprecated. QSqlQuery copy semantics cannot be implemented
correctly, as it's not generally possible to copy a result set
of a query when copying the corresponding QSqlQuery object. This
resulted in modifications on a QSqlQuery having visible (and
unintended) side effects on its copies. Instead, treat QSqlQuery
as a move-only type.
