If a type is trivially default constructible, QMetaType (and QVariant)
think that it can be built and value-initialized by zero-filling a
region of storage and then "blessing" that storage as an actual instance
of the type to build. This is done as an optimization.
This doesn't work for all trivially constructible types. For instance,
on the Itanium C++ ABI, pointers to data members are actually
value-initialized (= zero-initialized, = initialized to null) with the
value -1:
https://itanium-cxx-abi.github.io/cxx-abi/abi.html#data-member-pointers
This means that a type like
struct A { int A::*ptr; };
is trivially constructible, but its value initialization is not
equivalent to zero-filling its storage.
Since C++ does not offer a type trait we can use for the detection that
we want to do here, and since we have also decided that Q_PRIMITIVE_TYPE
isn't that trait (it just means trivially copyable / destructible), I'm
rolling out a custom type trait for the purpose.
This type trait is private for the moment being (there's no
Q_DECLARE_TYPEINFO for it), and limited to the subset of scalar types
that we know can be value-initialized by memset(0) into their storage
(basically, all of them, except for pointers to data members).
The fix tries to keep the pre-existing semantics of
`QMetaType::NeedsConstruction`. Before, the flag was set for types which
were not trivially default constructible. That included types that
aren't default constructible, or types that cannot do so trivially.
I've left that meaning unchanged, and simply amended the "trivial" part
with the custom trait. A fix there (to clarify the semantics) can be
done as a separate change.

We need to redirect the console output to the parent process

But we don't want to change the default behavior of Qt, so
we control this feature through an environment variable

(1) "new": the application will try to create a separate
console window and redirect everything (cin/cout/clog/cerr)
to it. If you are running the application in an IDE, you
won't be able to get anything from the IDE's console anymore.
(2) "attach": the application will try to attach to the parent

Since Android's platform permission API doesn't have an

return Undetermined, until a requestPermission() call
is done which updates the internal hash, and after that

When submitting applications to the iOS and macOS AppStore the
application goes through static analysis, which will trigger on
uses of various privacy protected APIs, unless the application
has a corresponding usage description for the permission in the
Info.plist file. This applies even if the application never
requests the given permission, but just links to a Qt library
that has the offending symbols or library dependencies.
To ensure that the application does not have to add usage
descriptions to their Info.plist for permissions they never
plan to use we split up the various permission implementations
into small static libraries that register with the Qt plugin
mechanism as permission backends. We can then inspect the
application's Info.plist at configure time and only add the
relevant static permission libraries.
Furthermore, since some permissions can be checked without any
usage description, we allow the implementation to be split up
into two separate translation units. By putting the request in
its own translation unit we can selectively include it during
linking by telling the linker to look for a special symbol.
This is useful for libraries such as Qt Multimedia who would
like to check the current permission status, but without
needing to request any permission of its own.

Many features of today's devices and operating systems can have
significant privacy, security, and performance implications if
misused. It's therefore increasingly common for platforms to
require explicit consent from the user before accessing these
features.
The Qt permission APIs allow the application to check or request
permission for such features in a cross platform manner.
The check is always synchronous, and can be used in both
library and application code, from any thread.
The request is asynchronous, and should be initiated from
application code on the main thread. The result of the request
can be delivered to lambdas, standalone functions, or
regular member functions such as slots, with an optional
context parameter to manage the lifetime of the request.
Individual permissions are distinct types, not enum values,
and can be added and extended at a later point.

The aboutToQuit signal is documented to be emitted "when the application
is about to quit the main event loop", which is useful "if your application
has to do some last-second cleanup", and is recommended over "putting it in
your application's main() function because on some platforms the exec() call
may not return".
However, if we're on a platform where the exec call may not return, it
will be because the event dispatcher's exec doesn't return, which means
we'll never get out of the call to eventLoop.exec(QEventLoop::ApplicationExec)
and into the execCleanup() code.
In addition, on macOS, where we do currently return to main(), we do so
by telling the platform to cancel the application termination, by returning
NSTerminateCancel from applicationShouldTerminate, after running the quit
logic of Qt via QWindowSystemInterface::handleApplicationTermination().
In the case of quitting applications due to system logout/shutdown, this
cancellation brings up a dialog saying the Qt application interrupted the
process, which luckily disappears again as soon as the application
actually terminates via main(). Moving the emit of aboutToQuit() earlier
in the flow, before we've cancelled the application termination, reduces
the chance that long running code triggered from this signal will keep the
dialog visible to the user.

The fact that Boost has BOOST_UNREACHABLE_RETURN() indicates that
there are compilers that complain about a lack of return after
Q_UNREACHABLE (we know that MSVC, ICC, and GHS are among them), as
well as compilers that complained about a return being present

private implementation and subStmt() is a private matcher that gives
access to SwitchCase's SubStmt.
A.k.a. qt-use-unreachable-return.
There were some false positives, suppressed them with NOLINTNEXTLINE.
They're not really false positiives, it's just that Clang sees the
world in one way and if conditonal compilation (#if) differs for other
compilers, Clang doesn't know better. This is an artifact of matching
two consecutive statements.
I haven't figured out how to remove the empty line left by the
deletion of the return statement, if it, indeed, was on a separate
line, so post-processed the patch to remove all the lines matching
^\+ *$ from the diff:
git commit -am meep
git reset --hard HEAD^
git diff HEAD..HEAD@{1} | sed '/^\+ *$/d' | recountdiff - | patch -p1
[ChangeLog][QtCore][QtAssert] Added Q_UNREACHABLE_RETURN() macro.

We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.
Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.
