Tor Arne Vestbø e0bb9e81ab Don't override QDialog::setVisible() to implement native dialogs
Clients who called the base-class implementation in QDialog would
as a result start hitting the canBeNativeDialog code path at the
start of QDialog::setVisible(), which would show the native dialog,
but without updating the QWidget visibility state.

To keep things 100% compatible, we shuffle the implementation of
QDialog::setVisible() into QDialogPrivate, which allows us to
override it in QMessageBoxPrivate and QErrorMessagePrivate.

The existing subclasses of QDialog that override setVisible have
been left as is, to not cause any unintended behavior change.

Pick-to: 6.5
