7f80c96432 Stabilize tst_QApplication::touchEventPropagation
CI metrics show that this test was flaky ~38 time in 3 days.
The problem is old: after we get a surface, a window manager can still
decide to re-position the window.
The fix is to simply send the touch event in a position where it is sure
to hit the window (usually the offset is the title bar height).

The blacklisting seems to not have worked, I could reproduce the failure
on a linux/xcb machine.

be0a221ae4 Fix missing handling of columns when merging selection ranges
This commit fixes two bugs:
1) Two ranges should not be merged if they are of different columns.
The old code would have merged (0,0) with (1, 1). Tranforming a selection
of just two indexes in a rectangle of four indexes.
2) The QItemSelectionRange appended had wrong column and worked only for
indexes of the first column. For example if 'tl' was (0, 1) than br was (0, 1)
so the QItemSelectionRange would have be ((0,1), (0, 1-1)) so ((0,1), (0,0)).
This QItemSelectionRange is invalid because topLeft columns is greater than
bottomRight column. The fix take in consideration the bottomRight column.

a30c746ea4 Introducing multiscreen-menus manual test
We have been noticing several menu popup sizing issues
in the presence of multiple, heterogenous displays.
Most remarkably, we'd often pick the primary display's
geometry when computing the menu's size hint. This results
in usability issues if the primary display is smaller than
the display onto which the menu popup is being displayed.

This manual test covers menu bar, context and push button
menus. Torn-off menus are also enabled. We turn off the use
of native menu bars to cover a few more cases.

124b9a6ff8 Improve suppression of spurious socket notifications under Windows
There were still two cases where spurious notifications would be
possible:

    - user calls hasPendingDatagrams()/pendingDatagramSize() on UDP
      socket somewhere outside the slot connected to readyRead()
      signal (::WSARecvFrom posts FD_READ notification, even if
      a notification for incoming datagram already exists in the
      message queue);
    - a socket was registered to receive several types of event and
      WM_QT_ACTIVATENOTIFIERS message is located between the
      different events for this socket in the queue.

Provided patch ensures that the message queue is synchronized with
the Qt event processing mechanism and adds a way to detect spurious
notifications inside the window procedure.

check for that and, if it fails, just keep the label in the form we
found it in (it's valid STD3 anyway).

[ChangeLog][QtCore][QUrl] Fixed a bug that caused certain domain names
that look like Internationalized Domain Names to become corrupt in
decoded forms of QUrl, notably toString() and toDisplayString().

21dd5d314a QUrl: fix IDN whitelist checking when the TLD is in Unicode
The whitelist is kept in ACE form, so if the TLD came in Unicode, we
need to run ToASCII before we can check the whitelist. This is slightly
inefficient because we'll run the same operation later in this domain.

ff93eddfd5 tests/auto/gui: use new QTest::addRow() more
... for calculated test data names.

In tst_qimage.cpp, use QLatin1String instead of QString for image
format pretty-printing, to avoid needless memory allocation and, more
importantly in the context of this patch, to make the result usable
with addRow(), which does not support %ls.

597d4ff796 QThread: add static create function
In the spirit of std::thread, which takes a function to call and its
parameters, and runs it in a new thread. Since the user might want to
connect to signals, move QObjects into the new thread, etc., the new
thread is not immediately started.

Although technically all of this _should_ be implementable in pure
C++11, there is nothing in the Standard to help us not reinvent all the
plumbing: packing the decay'd parameters, storing them, invoking the
function over the parameters (honoring INVOKE/std::invoke semantics).
std::function does not do the job, as it's copiable and therefore does
not support move-only functors; std::bind does not have INVOKE
semantics.

I certainly do not want to reimplement all the required facilities
inside of Qt. Therefore, the full blown implementation requires C++17
(std::invoke).

In order to make this useful also in pre-C++17, there are two additional
implementations (C++11 and C++14) that support just a callable, without
any arguments passed to it. The C++11 implementation makes use of a
class to store and call the callable (even move-only ones); basically,
it's what a closure type for a C++14 lambda would look like.

An alternative implementation could've used some of the existing
facilities inside QObject::connect implementation that store a functor
(for the connect() overload connecting to free functions), namely:
the QtPrivate::QFunctorSlotObject class. However:

* QFunctorSlotObject does not support move-only callables (see
QTBUG-60339);
* QFunctorSlotObject itself is not a callable (apparently by design),
and requires to be wrapped in a lambda that calls call() on it;
* the moment QTBUG-60339 is solved, we'd need the same handwritten
closure to keep QFunctorSlotObject working with move-only callabes.

So: just use the handwritten one.

The C++14 implementation is a simplified version of the C++11 one,
actually using a generalized lambda capture (corresponding to the
handwritten C++11 closure type).

All three implementations use std::async (with a deferred launch policy,
a nice use case for it!) under the hood. It's certainly an overkill for
our use case, as we don't need the std::future, but at least std::async
does all the plumbing for us.

[ChangeLog][QtCore][QThread] Added the QThread::create function.
