If a window is blocked by a WindowModal dialog, it should not be
possible to trigger window shortcuts on that window if it receives
a WindowActivate event.
This currently happens if the blocked window gets clicked, because the
window becomes the active_window and then QApplication sends it a
WindowActivate event (this doesn't happen with application modal dialogs).
The correctWidgetContext() function calls QApplicationPrivate::tryModalHelper()
only if the shortcut context is ApplicationShortcut. This patch makes it
call even if the shortcut context is WindowShortcut.

QAction::setData() always emits changed() even without actual data change.
Original code lacks a guard to check if the data changes.
According to http://doc.qt.io/qt-4.8/signalsandslots.html,
adding guard also benefits to prevent infinite looping in case
of cyclic connections.

QWindowContainer assumed that a widget could never change from
native to non-native. This is not a fact when the window container
is reparented to toplevel and back. In this case, usesNativeWidgets
would be stuck at true, and parentWasChanged() would go down the
native widget path, triggering an assert.
The solution is to always recalculate the usesNativeWidgets bool.

When calling resize() from showEvent(), we'd set the full geometry
on the widget's QWindow. This resulted in the top-level window
being moved to the top-left corner, even though no other call to
move() or setGeometry() had happened before.
The solution consists on calling the proper QWindow methods depending
on whether setGeometry_sys() is called for a move, a resize or both.
Furthermore, this needs QWindow::resize() to set its position policy
to frame-exclusive. The documentation states that is already the case
and we're setting the full geometry on the platform window, so we need
to convey that bit of information.
This also solves the age-old conundrum: "### why do we have isMove as
a parameter?"

In the referenced bug report, dismissing a QFileDialog while the
Qt Virtual Keyboard was in use would result in a crash.
Dismissing a file dialog created with
e.g. QFileDialog::getOpenFileName() causes it to eventually be
destroyed. When this happens, it starts deleting its children. Each
child widget's destructor calls clearFocus(). In clearFocus(), there is
a block of code that emits QWindow::focusChanged(), passing the result
of focusObject() called on that widget's window.
QWidgetWindow::focusObject() could end up using itself as a fallback
focus object if it had no other focus objects (e.g. children) to use
instead, even though it was in the process of being destroyed; as were
all of its children. The Qt Virtual Keyboard plugin would then try to
use the focus object, even though it was in an invalid state.
To fix this problem, we return early from QWidgetWindow::focusObject()
if the window is in the process of being destroyed.

We can't just static_cast a child to QLayout, because the child might
not be a QLayout, and even if it was, we might be called from the
QObject destructor so we would not be a layout anymore.
Instead we can just qobject_cast the deleted object to a QLayout and
remove it from the layout with removeItem.
This would not take in account the case where we would be called because
the QLayout gets destroyed, so we handle this case from ~QLayout by
removing ourself from the parent.
Note that the comment in ~QLayout was wrong, as the layout gets destroyed
explicitly from ~QWidget, not from ~QObject.
