The native style may not match the program style and it
makes sense to give an option rather than forcing native style.
Before it could only be done with setting AA_DontUseNativeDialogs
on the app, but it is reasonable to use native file dialogs and
Qt styled messageboxes - and it is extremely cumbersome - especially
since messageboxes often can start save dialogs.
It can look a bit strange that these introduced options has just one
option (DontUseNativeDialog) and four functions, but this way it works
similar to QColorDialog, QFileDialog and QFontDialog.

[ChangeLog][QtCore] Introduced Q_NODISCARD_CTOR which resolves to
[[nodiscard]] attribute for constructors on compilers that support
it, and does nothing on other compilers.
Using [[nodiscard]] attribute on a constructor is a C++20 feature,
however in practice it is supported on most of the compilers that
we use in Qt 6. Clang generates a [-Wunused-value] warning, GCC
and MinGW generate a [-Wunused-result] warnings, and MSVC
generates a C4834 warning.
However, there are some exceptions.
The Integrity compiler provides the following warning:
"tst_qglobal.cpp", line 699: warning #3435-D:
the "nodiscard" attribute doesn't apply to constructors,
destructors, or routines with void return type
[[nodiscard]] explicit Test(int val) : m_val(val) {}
The QNX compiler (QCC 8.3.0) and GCC 9.3.1 on OpenSUSE generate
the [-Wattributes] warning:
tst_qglobal.cpp: In member function
'void tst_QGlobal::nodiscardConstructor()':
tst_qglobal.cpp:699:44: warning: 'nodiscard' attribute applied to
'tst_QGlobal::nodiscardConstructor()::Test::Test(int)' with void
return type [-Wattributes]
[[nodiscard]] explicit Test(int val) : m_val(val) {}
These warnings will lead to build failures when compiled with
-warnings-are-errors flag, so for these compilers the macro
does not do anything.
An attempt to use __attribute__((__warn_unused_result__)) was
also unsuccessful on these compilers, so this patch goes for
an easy solution, and simply checks
__has_cpp_attribute(nodiscard) >= 201907L
to decide if the attribute is supported or not.
This commit also introduces a syntax-only test, and also applies
the new macro to QMutexLocker, because not all platforms in the
CI build and run unit tests.

In Qt >= 6.1, < 6.5, a trivially constructible type would have the
NeedsDestruction flag set, but it's dtor pointer would have been null.
In Qt 6.5, the meaning of the NeedsDestruction flag was changed to be
more aligned with what the name suggests, and thus would only be set for
non-trivially destructible types. For QMetaType this was fine, but
QVariant has a check for acceptable metatypes which attempts to verify
whether a QMetaType is usable for QVariant. The check assumes the
semantics of Qt 6.5, and thus fails for metatypes created by older Qt
versions.
To fix this issue, we increment the QMetaType revision field, and only
check the metatype's destruction support if the revision is high enough.
In theory, that allows passing unsuitable metatypes from older Qt
versions to QVariant; however, such code would have been broken in prior
Qt releases already (which didn't attempt the check), and no code that
used to work in any released Qt version will break (as we simply skip a
check that was passing before).

Functions in Qt that take a callback need to support callables with or
without context objects, and member functions of an object. The
implementation of those overloads follows a pattern that ultimately
results in a QSlotObjectBase implementation being created and
passed to an implementation helper that takes care of the logic.
Factor that common pattern into a new helper template in QtPrivate
that returns a suitable QSlotObjectBase after checking that the
functor is compatible with the specified argument types.
Use that new helper template in the implementation of
QCoreApplication::requestPermission and QHostInfo::lookupHost.
The only disadvantage of centralizing this logic is that we cannot print
a more detailed error message indicating which argument types the
caller expects. However, that information is visible from the detailed
compiler errors anyway.

Move the logic of updating the scoll offset into the makeVisible
function, so that the scroll is only adjusted to either leave no gap
between the last tab and the right edge of the widget of there is still
a scroll; or to reset it to 0 if there is enough space for the entire
tab bar. Since layoutTabs does show and hide the scroll buttons, we
cannot skip this when the buttons are invisible. However, the
normalizedScrollRect helper now needs to return the entire widget rect
if there are no visible scroll buttons.
Add a test case that simulates the previously broken behavior where
the scroll got unnecessarily reset to 0 when resizing.

- Definition of 'standalone' attribute:
An XML declaration containing the attribute 'standalone' with its
value set to 'yes', tells the parser to ignore markup declarations
in the DTD and to use them only for validation.
The declaration attribute is optional and defaults to 'no'.
- Behavior Qt5
In qt5, DOM documents contained the standalone attribute,
regardless of whether or not it was explicitly specified.
- Behavior Qt6
In Qt6, the standalone attribute was only contained in a DOM document,
if its value was 'yes'. If it was explicitly declared with the value
being 'no', it was dropped in the DOM document.
- Expected behavior
If the source specified it overtly, then the generated XML should
contain the attribute, even when it takes its default value.
- Code base
QXmlStreamReader provides a public bool getter isStandaloneDocument().
This says whether the document is standalone or not.
The information whether the attribute was actually specified gets lost.
In consequence, the attribute was always dropped on non-standalone
documents.
- Fix
This patch makes hasStandalone a member of QXmlStreamReaderPrivate, to
record whether the attribute has been explicitly specified.
QDomParser is modified to retain the standalone attribute, if
QXmlStreamReaderPrivate::hasStandalone is true.
- Test
The patch adds a test function in tst_QDom.

This avoids the creation of the timer in the wrong thread and

To avoid that the timer is created when it has already expired in
