The gc_sections linker flag was recently wrapped in a
$<CXX_COMPILER_ID> genex to prevent adding it the command line when
using an incompatible compiler.
This causes an issue when generating .pc pkg-config files because
$<CXX_COMPILER_ID> can't be used in the output of a file(GENERATE)
call.
Record the flag in a global property, both the genex-wrapped and bare
forms, so that we can perform a string replacement when generating
the pkg-config file to remove the genex wrapping.
This is not perfect, in the sense that consumers of the .pc file
might get the wrong flag if using an incompatible compiler, but
it's better than outright failing the Qt build.
Distros will be expected to patch the .pc files if necessary.
Note the issue does not usually happen for regular Qt builds because
gc_sections is only enabled automatically for static builds, but for
static builds we don't currently generate .pc files.
So the issue only happens in shared Qt builds where the gc_sections
feature is enabled manually.

QWidget re-uses an existing backing store. Platform windows depend on
being associated to a backing store, in case they become toplevel
windows. If a platform window gets deleted and re-created each time it
is shown or hidden, it has to be manually associated to the re-used
backing store.
This patch partly reverts fbf0aeea7d3b38ced7a16fcd5c3e2e9b45536292.
It removes Android specific code from QWidgetPrivate::create(), which
has been added to suppress re-using backing stores in the absence of

QWidget re-uses backing stores created in QWidgetPrivate::create().
The Android platform plugin creates a new platform window, when a
widget becomes a toplevel window. When it is hidden, the platform
window is deleted. The link between QAndroidPlatformWindow and its
backing store is made in the constructor of
QAndroidPlatformBackingstore. When a new QAndroidPlatformWindow is
constructed and the backing store is re-used, there is no more link
between platform window and platform backing store.
This has lead to screen assets not being painted, when shown more than
once.
This patch forces QWidgetPrivate::create() to construct a new backing
store on Android. This way, toplevel windows always have a backing
store associated with it. It adds an assertion to
QAndroidPlatformScreen::addWindow(). That will make e.g.
tst_QWidget::visible() crash without the fix.

Setting the parent of a QObject to nullptr means the ex-parent no
longer owns and deletes the object as its child, leaking it.
Fix by creating a scope-guard to defer deletion until the tests have
run.
This is simpler than the alternatives:
Putting it into unique_ptr would require a new variable name, or a
larger refactoring of the function, because the `test` variable is
being re-used for many different objects in the course of the
function, most of which should not be deleted.
Using QAutoPointer would drag in QtWidgetsPrivate, and the class is
probably not available in all active branches.
Finally, deleteLater() would require reliably returning to the event
loop, which may not happen if the test is run in isolation.

In C++20 std::basic_string_view has gained a range constructor (like
QStringView always had), but that range constructor has been made
explicit. This means we can't just pass a QString(View) to a function
taking a u16string_view. The consensus seems to be that that types that
should implictly convert towards stdlib's string views should do that
via implicit conversion operators. This patch adds them for
* QByteArrayView => std::string_view
* QString(View) => std::u16string_view
* QUtf8StringView => std::string_view or std::u8string_view, depending
on the storage_type
QLatin1StringView doesn't have a matching std:: view so I'm not enabling
its conversion.
QByteArray poses a challenge, in that it already defines a conversion
towards const char *. (One can disable that conversion with a macro.)
That conversion makes it impossible to support:
QByteArray ba;
std::string_view sv1(ba); // 1
std::string_view sv2 = ba; // 2
because:
* if only operator const char *() is defined, then (2) doesn't work
(situation right now);
* if both conversions to const char * and string_view are defined, then
(1) is ambiguous on certain compilers (MSVC, QCC). Interestingly
enough, not on GCC/Clang, but only in C++17 and later modes.
I can't kill the conversion towards const char * (API break, and we use
it *everywhere* in Qt), hence, QByteArray does not get the implicit
conversion, at least not in this patch.
[ChangeLog][QtCore][QByteArrayView] Added an implicit conversion
operator towards std::string_view.
[ChangeLog][QtCore][QString] Added an implicit conversion operator

as its storage type in Qt 6). Note that QUtf8StringView is planned to
use char8_t in Qt 7, therefore it is expected that the conversion will
change towards std::u8string_view in Qt 7.

The old code violated the following principles:
- DRY: the same code occurred 3× in the code-base
- SCARY: the vast majority doesn't actually depend on template
arguments, causing template bloat
Solve both with a tiered Extract Method.
We cannot change the order of the operations performed on
QBasicFutureWatcher, in particular not the connect() to the
contination w.r.t. setFuture(), so we cannot leave the connect to the
continuation lambda outside the function, as it would mean to also
leave the setFuture() call outside.
Thanks to Volker's makeCallableObject(), we can, however, type-erase
the lambda using QSlotObjectBase, which is what connect() internally
creates, anyway, therefore bringing the whole function behind the ABI
boundary.
As a non-QObject, non-QMetaObject friend, we're lacking support for
actually doing something useful with a QSlotObjectBase, but that can
be fixed in the implementation now. The interface is stable, which is
what matters for 6.6 now.
This will allow a subsequent commit to drag QBasicFutureWatcher behind
the ABI boundary, unexporting it.

When configuring the project the first time, QT_BUILDING_QT is not

But because standalone projects implicitly include QtSetup.cmake,
that file sets the QT_BUILDING_QT cache var to true, and upon test
reconfiguration, cmake errors out with:
Unknown CMake command "qt_internal_add_test"

This happens because QT_BUILDING_QT is true on the second
