When a foreign event loop that does not enter an alertable wait state
is running (which is also the case when a native dialog window is
modal), pipe handlers would freeze temporarily due to their APC
callbacks not being invoked.
We address this problem by moving the I/O callbacks to the Windows
thread pool, and only posting completion events to the main loop
from there. That makes the actual I/O completely independent from
any main loop, while the signal delivery works also with foreign
loops (because Qt event delivery uses Windows messages, which foreign
loops typically handle correctly).
As a nice side effect, performance (and in particular scalability)
is improved.
Several other approaches have been tried:
1) Using QWinEventNotifier was about a quarter slower and scaled much
worse. Additionally, it also required a rather egregious hack to
handle the (pathological) case of a single thread talking to both
ends of a QLocalSocket synchronously.
2) Queuing APCs from the thread pool to the main thread and also
posting wake-up events to its event loop, and handling I/O on the
main thread; this performed roughly like this solution, but scaled
half as well, and the separate wake-up path was still deemed hacky.
3) Only posting wake-up events to the main thread from the thread pool,
and still handling I/O on the main thread; this still performed
comparably to 2), and the pathological case was not handled at all.
4) Using this approach for reads and that of 3) for writes was slightly
faster with big amounts of data, but scaled slightly worse, and the
diverging implementations were deemed not desirable.

QGuiApplicationPrivate::processMouseEvent() sends a
QWindowSystemInterfacePrivate::TouchEvent if the mouse event is not
accepted and AA_SynthesizeTouchForUnhandledMouseEvents is enabled.
A QPA TouchEvent always contains native touch points, which is why
it calls QWindowSystemInterfacePrivate::fromNativeTouchPoints to
translate the QMouseEvent's device-independent position back to the
raw position that it would have had if it came from a real touchscreen.
Therefore we must give that function touchpoints that are actually in
native coordinates.
It may be that some of this transformation could be avoided entirely,
but here we prove that the existing way works correctly, by adding
coordinate checking to the tst_QWindow::mouseToTouchTranslation() test.

In 4e400369c0 we deprecated
normalizedPos() because we suspect it's a legacy feature that few
users will need. However Qt developers keep bringing up the continued
usage in autotests over and over. (It's IMO not wrong to keep testing
deprecated functions in autotests, but the warning keeps attracting
attention.)
Of course it will turn out that normalizedPos() has users; we just
don't know how many. One way to look at it is: why should they copy
a snippet of code to calculate it, when it costs us so little to
continue to provide this accessor.
It might also turn out that some users will complain that in Qt 5
it was passed through from the device driver (or at least from the
window system API) to the application, and perhaps the replacement will
not always work, for example if availableVirtualGeometry() ends up
wrong, or there is some strange scenario that generates events that are
out-of-bounds for the device that the event professes to come from, so
that the "normalized" coordinates also go outside the [0..1] range.
We reserve the right to put back the storage in QEventPointPrivate if
the need arises; so that's why this function is not inline.
We continue to hope that startNormalizedPos() and lastNormalizedPos()
are used even less and won't be missed much, because it would be
wasteful to store them all the time if only a few users need them.

In Qt Quick, when we deliver an item-specific QTouchEvent that contains
only the subset of eventpoints that are inside the Item's bounds,
traditionally the Item can accept the event to tell the delivery logic
that the event is handled and doesn't need to be delivered further.
But an Item cannot be expected to have total scene awareness; so now,
the delivery is "done" only when all eventpoints in the original event
are accepted. This behavior has been working well enough already due to
logic in QQuickWindow that iterates the points and accepts them if the
event is accepted; but it seems appropriate to move this enforcement
into QPointerEvent itself. Making setAccepted() virtual gives us a
useful degree of freedom.
Event-handling code should alternatively use QEventPoint:setAccepted()
or QPointerEvent::setExclusiveGrabber() to take resonsibility for only
a subset of the touchpoints.
Another way to put it is that we treat QPointerEvent::setAccepted() as a
convenience method: accepting the QEventPoints is what counts (at least
in Qt Quick).

QQuickEventPoint instances were very long-lived and got reused from one
event to the next. That was initially done because they were "heavy"
QObjects; but it also became useful to store state in them between
events. But this is in conflict with the ubiquitous event replay
code that assumes it's OK to hold an event instance (especially
a QMouseEvent) for any length of time, and then send it to some widget,
item or window. Clearly QEventPoints must be stored in the QPointerEvent,
if we are to avoid the need for workarounds to keep such old code working.
And now they have d-pointers, so copying is cheap. But replay code
will need to detach() their QEventPoints now.
QEventPoint is useful as an object to hold state, but we now store
the truly persistent state separately in an EventPointData struct,
in QPointingDevicePrivate::activePoints. Incoming events merely
update the persistent points, then we deliver those instead.
Thus when event handler code modifies state, it will be remembered
even when the delivery is done and the QPA event is destroyed.
This gets us a step closer to supporting multiple simultaneous mice.
Within pointer events, the points are moved up to QPointerEvent itself:
QList<QEventPoint> m_points;
This means pointCount(), point(int i) and points() can be non-virtual.
However in any QSinglePointEvent, the list only contains one point.
We hope that pessimization is worthwhile for the sake of removing
virtual functions, simplifying code in event classes themselves, and
enabling the use of the range-for loop over points() with any kind of
QPointerEvent, not just QTouchEvent. points() is a nicer API for the
sake of range-for looping; but point() is more suited to being
non-const.
In QML it's expected to be OK to emit a signal with a QPointerEvent
by value: that will involve copying the event. But QEventPoint
instances are explicitly shared, so calling setAccepted() modifies
the instance in activePoints (EventPointData.eventPoint.d->accept);
and the grabbers are stored separately and thus preserved between events.
In code such as MouseArea { onPressed: mouse.accepted = false }
we can either continue to emit the QQuickMouseEvent wrapper
or perhaps QEvent::setAccepted() could become virtual and set
the eventpoint's accepted flag instead, so that it will survive
after the event copy that QML sees is discarded.
The grabChanged() signal is useful to keep QQuickWindow informed
when items or handlers change exclusive or passive grabbers.
When a release happens at a different location than the last move event,
Qt synthesizes an additional move. But it would be "boring" if
QEventPoint::lastXPosition() accessors in any released eventpoint always
returned the same as the current QEventPoint::xPosition()s just because
of that; and it would mean that the velocity() must always be zero on
release, which would make it hard to use the final velocity to drive an
animation. So now we expect the lastPositions to be different than
current positions in a released eventpoint.
De-inline some functions whose implementations might be subject to
change later on. Improve documentation.
Since we have an accessor for pressTimestamp(), we might as well add one for
timestamp() too. That way users get enough information to calculate
instantaneous velocity, since the plan is for velocity() to be somewhat
smoothed.
