b480acb372 Allow for private properties to be implemented using QProperty
Recently the moc learned that Q_PROPERTY(int x ...) can mean that "x" is
implemented as QProperty and then allows installing bindings, etc. -
this works by scanning the same class' members.

For our own use of QProperty, we need to place the QProperty member
itself into the d-pointer to be able to maintain the ability to add new
properties without breaking binary compatibility. That however means
that moc can't know that a certain property is backed by QProperty - we
don't scan the members of the private class.

As a workaround, this change enables the syntax where the property type
used in Q_PRIVATE_PROPERTY may be wrapped with QProperty<T>.

In addition this patch fixes the compilation of such declared properties
by ensuring the accessor prefix (t->$accessor) is applied also for the
QProperty related meta call variants.

382577419a QNAM/QNetConMon: Update handling of QNetworkConnectionMonitor::start
QNetworkConnectionMonitor::start was previously called after checking
d->networkAccessible, unfortunately that means if the network was
unavailable when QNetworkConnectionMonitor was created we don't
subscribe to updates or recheck the status (unless
QNetworkAccessManager::networkAccessible() is called).

Move the call to start to before the offline check. Also update the
Windows backend so that it updates networkAccessible on the call to
start()

Pick-to: 5.15

c78a960198 QCOMPARE: treat values as equal if qFuzzyIsNull(each)
We hope this shall avoid some flaky failures noticed in quick tests,
e.g. tst_QQuickMenu::Material::subMenuPosition(cascading,flip) was
recently seen failing with 3.88e-11 != 0. This required some revision
to test data in the testlib selftest for floats; the resulting
expected output differs in details but not in which tests pass or
fail. QEMU, naturally, made life difficult, requiring special-case
code in the test-driver.

[ChangeLog][QtTestLib][QCOMPARE] QCOMPARE() now treats its values as
equal when qFuzzyIsNull() is true for both of them.

52a2505672 QCborValue: avoid signed integer oveflows when decoding time_t
QDateTime::fromSecsSinceEpoch() multiplies by 1000 but does not check
for overflow. That means we must do so in QCborValue validation. We
can't use mul_overflow<qint64> on 32-bit platforms, so we do a compare-
and-branch there. For 64-bit platforms, we prefer to do the
multiplication with checked overflow, as the common case is that it will
not overflow and we'll need the multiplication anyway.

Controls 1 needed it, but here we are: Qt 5 is "done", this still wasn't

to add a property on the focus object that the iOS plugin can query, and
give us a menu that has Copy instead of Paste.

1af7fb5ed8 rhi: Warn better in D3D/Vulkan for incompatible multisample resolve formats
Attempting to resolve a multisample image into a non-multisample one
is only valid when the formats are the same, as per Vulkan spec and D3D
docs.

With Vulkan, this is sometimes not fatal, some implementations can
apparently deal with some format combinations, so the problem may not be
trivial to catch, although with validation layer enabled a warning is
shown at least. To make it easier to discover, have our own warning.

8ddd3ee60b Revert "CMake: qt_find_package() enable debug behavior by default"
It broke configuration of qtwayland standalone tests, due to qtwayland
doing 3 separate qt_find_package(Wayland) calls with the same package
but different arguments in 3 different directory scopes.

The top scope didn't have PROVIDED_TARGETS argument. The rest of the
scopes did have the arguments with either Server or Client, but because
of the debug behavior above being enabled by default the dependencies
weren't registered in the Qt6WaylandClientDependencies.cmake file (and
the server equivalent).

The registration didn't happen due to the skipping logic, when a package
is found and the targets already exist.

This led to standalone tests failing to configure because they tried
linking against non-existent Wayland::Client and Wayland::Server
targets.

This reverts commit dd7e40b108.

a4071c18de Get rid of virtual inheritance from ThreadEngineBase
The virtual inheritance causes the issue, when adding
new, non-default constructor to the base ThreadEngineBase
class. It looks like classes derived from it can't
use the non-default constructor, even when it's called
explicilty from the subclass. Instead, the default constructor of the
ThreadEngineBase class is always required during compilation
and called on runtime.

In addition, the only sensible use of the virtual inheritance
is the multiple inheritance, but apparently it looks like
there is no single class in Qt which would multi inherit from
the ThreadEngineBase class, so this change shouldn't have any bad
side effects. This justifies the current lack of info on why it
was introduced originally ages ago.

f2347077f5 Always open a text control's context menu on the same screen
It's very disorienting when a context menu pops up on a different
screen from where the right mouse button was clicked.
QWidgetPrivate::setScreenForPoint() can give incorrect results in
multi-screen desktop configurations; but we can give the menu a hint
by setting initialScreenIndex, which was originally used only when
QDesktopScreen or QDesktopScreenWidget is the parent (see
b3fc5e1ea3 ).
