fc35f94964 winrt: Rework handling of udp datagrams
We may only emit the readReady signal once for every event loop
iteration. The previous implementation lead to the situation that the
socket engine stopped reading socket data when bursts of data was
received. In this case several readReady signals were fired. The socket
engine obtained the pending datagrams (not only the first one) and for
the following readReady signal no datagram was present. In this case the
socket engine stops reading and the engine stalls.

The new approach emits the readyRead signal at the most once every event
loop iteration. The list of new pending datagrams is queued to be added
to the "real" pending datagram list at the same time as the readyRead
signal. Thereby we avoid the situation that a client can read all the
datagrams before readyRead is emitted.

One more advantage of having the worker handle the pending datagrams
is that we no longer have to access the socket engine's members inside
the callback. Thus we avoid the situation, where a late callback can
make the application crash when the socket engine has already been
deleted.

91cde06296 Extracted cleanup from QCoreApplication::exec() into separate function
Not all Qt integration points can call QCoreApplication::exec(), in
particular, ActiveQt. When an ActiveQt server is loaded, it tries to
mimic the behavior of calling QCoreApplication::exec() by setting
QCoreApplicationPrivate::in_exec = true. However, when unloading the
DLL it is necessary to call the same clean-up (e.g. deferred delete)
that QCoreApplication::exec() does. Extracting the cleanup in a separate
function means implementation does not have to be duplicated.

310bf3f57c Make sure flags from library detections go to the right places
Split them and add -I flags to INCLUDEPATH and -D flags to
DEFINES. Anything else gets reported as a problem and dropped.

This has the benefit that qmake will automatically use -isystem for
those paths if they lie in a system directory. As a consequence of that,
we won't get any warnings in headers located there. There are multiple
cases of glib, gtk, etc. headers producing warnings (such as enums
ending in comma). This does not fix warnings produced by use of macros
declared in system headers, though...

33d748bb88 Allow granular synchronous and asynchronous delivery of QPA events
The setSynchronousWindowSystemEvents() API of QWindowSystemInterface is
supposed to be set globally by the platform plugin, not switched on and
off to trigger async/sync deliver of events for a specific event.

We introduce processWindowSystemEvent() in QWindowSystemInterfacePrivate
to match postWindowSystemEvent(), where the former is synchronous and
the latter is asynchronous.

This is then coupled with a templated version of handleWindowSystemEvent()
that then calls out to one of the two depending on the specialization
that's used. The default specialization will decide based on the state
set by setSynchronousWindowSystemEvents(), as before.

This allows templated versions of handleMouseEvent, handleKeyEvent, etc
to be added without maintaining two code paths, one for synchronous
and one for asynchronous delivery, which in the end allows us to
get away from using setSynchronousWindowSystemEvents() as a temporary
switch to synchronous mode.

The templates are defined in the QWindowSystemInterface source file,
with explicit instantiations of the three supported modes of delivery,
as having the definition in the header file would both require inlining,
as well as qwindowsysteminterface.h having access to the private parts
of QWindowSystemInterfacePrivate for the template function bodies.

5cc0d92c24 QAbstractItemView: use only a 1x1 QRect for selecting on mouse press
Before commit f1e9076809, mousePressEvent
called the virtual method setSelection(const QRect&, SelectionFlags)
with the 1x1 rectangle which contains only the clicked QPoint, unless
the SelectionFlag "Current" was set because Shift was pressed during
the mouse press.

Since that commit, the behavior has been changed such that the
rectangle is the one that is spanned by the center of the clicked item
and the clicked pixel. In theory, the result should be the same (i.e.,
only the clicked item should be selected), but

* the code path in QListView::setSelection for 1x1 QRects is more
  efficient, and
* using a larger QRect can cause problems with custom views, see the
  comments in QTBUG-18009

This commit ensures that the 1x1 QRect is used again, unless the
SelectionFlag "Current" is used.

f9acbaccde QPixmap::load: ensure QBitmap stays a QBitmap even on failure
... and avoid detach()ing potentially large data for just
preserving the QPlatformPixmap::pixelType().

A QBitmap differs from a QPixmap (its base class, urgh)
by always having a data != nullptr and a Bitmap pixel
type, yet load() was unconditionally setting 'data' to
nullptr on failure, turning a QBitmap into a non-QBitmap.

Fix by move-assigning a null QBitmap instead of resetting
'data'.

Add some tests.

Fix by moving the setParentItem(nullptr) call up the call stack
into ~QGraphicsWidget(), ensuring that the object is still a
QGraphicsWidget when these calls are made.

daaa1a287b Plug leak in QFormLayout::setWidget()
Unlike layouts and spacer items, a QWidget is-not-a QLayoutItem.
QWidgetItem simply wraps the QWidget, so in QFormLayout::setWidget(),
we allocate a widget item for the widget passed, and hand that down
to Private::setItem() for adding to the various data structures.

Private::setItem() has a bunch of guard clauses, though, that return
without deleting the item.

A test triggered this code path and made asan complain.

This is just one part of a larger problem: QFormLayout::setLayout()
normally takes ownership of the layout passed, because QLayouts own
their QLayoutItems, and QLayout is-a QLayoutItem. But setLayout()
fails to live up to the owner role when it fails to add a layout,
and there's no easy way for the API user to check for success.

A fix for this breaks tst_qformlayout, and while those checks that
break deserve to be broken, I'll refrain from proposing the larger
fix for 5.6 LTS, but will propose it for 5.8 or 5.9 instead.

This fix here only fixes the leak in setWidget() by adding a bool
return to Private::setItem() informing Private::setWidget() of the
need to manually delete the item it allocated for the widget.

0f21e0bc19 QDBusDemarshaller: use RAII in duplicate()
QtDBus is compiled with exceptions disabled, but checkers
don't know that, and it's not 100% certain it will stay
that way until eternity.

So do the simple change and hold the new'ed pointer in a
QScopedPointer until handing it off to create().

3c274d4e3e QTableGenerator: give some TLC to the sorting predicate
- Provide op()(uint[], QComposeTableElement) as well, since the
  standard (does|did) not specify in which order the two are called.
- Use std::lexicographical_compare to do the ... lexicographical
  comparison.
- Share code by calling a new op()(uint[], uint[]) overload from all
  other overloads.
- Mark all op() overloads const noexept.
- Rename from 'Compare' to 'ByKeys', as in 'sort(vector, ByKeys()))'.
- Replace a hand-rolled loop with std::equal.
- Replace a #define with a static constexpr variable.
