In commit c6c93041

, the earlier size limit of 128 was raised to the
format's defined maximum of 256. But the required special storage of
this size in the image structures was not implemented. Hence,
attempting to store such big icons would result in invalid image
files.

Fix the size storing details, and add some autotests of ico format

We guard QWidgetWindow's widget with a QPointer to avoid
sending it events during destruction (which may result in
undefined behavior, since this originates from ~QObject and
we expect the object to behave as a QWidget). Therefore, we
need to harden all access to that widget since it can now
be null, specially during destruction.

As an example, QGestureManager may crash when we delete a
top-level widget. The crash stack trace is:

1  QScopedPointer<QObjectData, QScopedPointerDeleter<QObjectData>>::data() const
2  QScopedPointer<QObjectData, QScopedPointerDeleter<QObjectData>>::pointer qGetPtrHelper<QScopedPointer<QObjectData, QScopedPointerDeleter<QObjectData>>>(QScopedPointer<QObjectData, QScopedPointerDeleter<QObjectData>> const&)
3  QWidget::d_func()
4  QGestureManager::filterEvent(QWidget *, QEvent *)  <-- the widget ptr is null
5  QGestureManager::filterEvent(QObject *, QEvent *)
