Due to the bug related to the 'new syntax' signal/slot connections,
it's unfortunately possible to have a connection not deleted properly
by the moment children objects get deleted. Then, as a result,
in e.g. QSslSocket's destructor the socket will change its state,
triggering the (now deleted) UI elements' access.
Note - the original bug was reported, the patch (only possible?) was
not accepted.

I made a clazy automated check that replaced the use of QVariant::Type

In addition, there was some manual changes to fix the compilation errors.
Adapted the Private API of QDateTimeParser and QMimeDataPrivate
and adjust QDateTimeEdit and QSpinBox.
QVariant(QVariant::Invalid) in qstylesheet made no sense.
But note that in QVariant::save, we actually wanted to use the non-user type.
In the SQL module, many changes were actually reverted because the API
still expects QVarient::Type.

The logic is now mostly handled in QGuiApplication, with QApplication
only dealing with the widget-specific palettes and interaction between
the style and the palette.
The application now picks up changes to the platform theme and will
re-resolve the current application palette appropriately. This also
works even if an explicit application palette has been set, in which
case any missing roles are filled in by the theme.
The palette can now also be reset back to the default application
palette that's fully based on the theme, by passing in the default
constructed palette (or any palette that doesn't have any roles set).
This is also correctly reflected in the Qt::AA_SetPalette attribute.
Conceptually this means QGuiApplication and QApplication follow the
same behavior as QWidget, where the palette falls back to a base or
inherited palette for roles that are not set, in this case the theme.
Behavior-wise this means that the default application palette of the
application does not have any roles set, but clients should not have
relied on this, nor does QWidget rely on that internally.
It also means that setting a palette on the application and then
getting it back again will not produce the same palette as set,
since the palette was resolved against the theme in the meantime.
This is the same behavior as for QWidget, and although it's a
behavior change it's one towards a more sane behavior, so we
accept it.
[ChangeLog] Application palettes are now resolved against the platform's
theme palette, the same way widget palettes are resolved against their
parents, and the application palette. This means the application palette
reflected through QGuiApplication::palette() may not be exactly the same
palette as set via QGuiApplication::setPalette().
