ce8874fc3b CMake: Place resources into static libraries, not object libraries
During the Qt 5 -> Qt 6 and qmake -> CMake porting time frame, it was
decided to keep resources in an object file (object library), rather
than putting them directly into a static library when doing a static
Qt build, so that the build system can take care of linking the
object file directly into the executable and thus not forcing
project developers to manually initialize resources with
the Q_INIT_RESOURCE() macro in project code.

This worked for most qmake and cmake projects, but it created
difficulties for other build systems, in the sense that these projects
would have to manually link to the resource object files, otherwise
they would get link time errors about undefined resource symbols,
assuming they kept the Q_INIT_RESOURCE() calls.
If the project code didn't contain Q_INIT_RESOURCE calls, the
situation would be even worse, the linker would not error out,
and the missing resources would only be discovered at runtime.

It's also an issue in CMake projects that try to link to the
library files directly instead of using the library target names,
which means the object files would not be automatically linked in.
Many projects try to do that because we don't yet offer a convenient
way to install libraries and reuse them in other projects (the SDK
case), so projects end up shipping only the libraries, without the
resource object files.

We can improve the situation by moving the resources back into their
associated static libraries, and only keeping a static initializer as
a separate object file / object library, which references the actual
resource initializer symbol, to ensure it does not get discarded
during linking.

This way, projects that link using targets get no behavior difference,
whereas projects linking to static libraries directly can still
successfully build as long as their sources have all the necessary
Q_INIT_RESOURCE calls.

To ensure the resource symbols do not get discarded, we use a few new
private macros. We declare the resource init symbols we want to keep as
extern symbols and then assign the symbol addresses to volatile
variables.
This prevents discarding the symbols with the compilers / linkers we
care about.

It comes at the cost of an additional static initializer per resource,
but we would get the same + a bigger performance hit if we just used
Q_INIT_RESOURCE twice (once in the object lib and once in project
code), which internally needs to traverse a linked list of all
resources to check if a resource was initialized or not.

For GHS / Integrity, we also need to use a GHS-specific pragma to keep
the symbols, which we currently use in qtdeclarative to ensure qml
plugin symbols are not discarded.

The same macros will be used in a qtdeclarative change to prevent
discarding of resources when linking to static qml plugins.

A cmake-based test case is added to verify that linking to static
libraries directly, without linking to the resource initializer
object libraries, works fine as long as the project code calls
Q_INIT_RESOURCE for the relevant resource.

d1da83002d QByteArray: remove a unittest
It relied on an implementation detail of operator+=(), that the latter
wouldn't just use assignement (e.g. if `this` is empty/null).

It also had undefined behavior, when the char array used with
fromRawData() went out of, the nested, scope, the code was pointing to a
dangling stack pointer.

Thanks to Thiago for the explanation in code review.

This ties in with further changes in this series, where append() is
changed to preserve null-ness; there is no way to preserve null-ness in
append() while keeping this unittest passing.

eb0abd9789 Use QT_SUPPORTS_INT128 macro to handle 128-bit integral types
Introduce QT_SUPPORTS_INT128 and QT_NO_INT128 marcos to handle 128-bit
types. These macros allow to undef Qt's own 128-bit types and the
related code, but keep the compiler definitions unchanged.

This is required for Qt Bluetooth, where we need to use
QT_BLUETOOTH_REMOVED_SINCE to get rid of the APIs using
QtBluetooth-specific struct quint128 which clashes with the 128-bit
types. The idea is to use QT_NO_INT128 in Qt Bluetooth's
removed_api.cpp instead of directly undef'ing __SIZEOF_INT128__,
because the latter is UB.

This commit amends befda1acca.

In porting the selftest machinery to Catch2 in 24e83de8d1 we
accidentally added an unconditional early return when determining
whether to check for unexpected stderr output, resulting in not
checking error output on any platform.

The return statement has now been moved into the Q_CC_MINGW
condition, but as we now seem to have similar issues on macOS
and Linux with some of the tests outputting "Received signal 6
(SIGABRT)" as we do for QEMU, we need to add a few more explicit
early return conditions to the function.

2e9d33e534 Use correct index for QLocale::system()'s static
Nothing prevents client code from calling QLocale::setDefault() before
we ever instantiate QLocale::system() - aside from some quirks that
mean setDefault(), currently, does instantiate QLocale::system() to
force initialization of defaultLocalePrivate - so using defaultIndex()
could set the system QLocalePrivate instance's index incorrectly.

In any case, even if the index is initially set correctly, a
subsequent change to the system locale would change the correct index;
and nothing outside QLocale::system() has access to the instance that
would then be remembering an out-of-date index.

Actually tripping over that inconsistency took some deviousness, but
was possible. The index is (currently) only used for month name
lookups and those special-case, for the Roman-derived calendars, the
system locale, to only use the index if the system locale offers no
name for a month. Meanwhile, updateSystemPrivate() uses the fallback
locale's index for its look-up of which CLDR data to copy into the
fallback QLocaleData for the system locale.

None the less, a non-Roman calendar's lookup will go via the index to
get at the CLDR data for that calendar, thereby exposing the system
locale's index to use; and, sure enough, a setDefault() could lead
that to produce wrong answers.

In QLocale::system() there's a cached QLocalePrivate, whose index we
need to ensure stays in sync with the active system locale. So pass
its &m_index to systemData(), which will now (when passed this) ensure
it's up to date. Since we always have called systemData(), to ensure
it is up to date, we can skip that update in the initialization of the
cached private and use m_index = -1 to let systemData() know when it's
in the initial call, thereby making the static cache constinit.

Amended a test to what proved the issue was present.

4b0261fed0 tst_QFuture: fix UB (call of member function on wrong object)
By the time QObject::destroyed() is emitted from ~QObject(), sender no
longer is-a SenderObject, only a QObject, so calling a SenderObject
member function on it is UB.

Says UBSan:

    tst_qfuture.cpp:3854:84: runtime error: member call on address 0x60200000e550 which does not point to an object of type 'SenderObject'
     0x60200000e550: note: object is of type 'QObject'
      00 00 00 00  e8 3f 96 c9 51 7f 00 00  80 3e 00 00 c0 60 00 00  02 11 00 00 08 00 00 00  16 00 00 72
                   ^~~~~~~~~~~~~~~~~~~~~~~
                   vptr for 'QObject'

Fix by removing the QObject::connect().

This, of course, breaks the test's WHEN, but I don't see how to keep
that WHEN without the UB. At least the THEN part is not invalidated,
and there doesn't appear to be another test that tests that destroying
objects before signal emission results in a cancelled future.

f82cf6333e Long live QSpan!
QSpan is Qt's version of std::span. While we usually try not to
reimplement std functionality anymore, the situation is different with
QSpan. Spans are non-owning containers, so the usual impedance
mismatch between owning STL and Qt containers doesn't apply here:
QSpan implicitly converts to std::span and vice versa, making STL and
Qt APIs using spans completely interoperable.

We add QSpan mainly for two reasons: First, we don't want to wait
until we require C++20 in Qt and can use std::span. Second, in the
view of this author, some design decisions in std::span hurt the
primary use-case of spans: type-erasure for containers. This results
in two major deviations of QSpan from std::span: First, any rvalue
container is convertible to QSpan, allowing seamless passing of owning
containers to functions taking spans:

    void sspan(std::span<T>);
    void qspan(QSpan<T>);

    std::vector<T> v();
    sspan(v()); // ERROR: rvalue owning container
    auto tmp = v();
    sspan(tmp); // OK, lvalue
    qspan(v()); // OK

This author believes that it's more helpful to have compilers and
static checkers warn about a particular wrong usage than to make
perfectly valid use-cases impossible or needlessly verbose to code.

The second deviation from std::span is that fixed-size span
constructors are also implicit. This isn't as clear-cut, because an
explicit QSpan{arg} isn't per-se bad. However, it means you can't
transparently change from a function taking decltype(arg) to one
taking QSpan and back. Since that's exactly what we intend to do in Qt
going forward, in the interest of source-compatibility, the ctors are
all implicit.

Otherwise, the API of QSpan follows the std::span API very
closely. Like std::span, QSpan isn't equality_comparable, because it's
not clear what equality means for spans (element-wise equal, or (ptr,
size)-wise equal?). The major API additions are Qt-ish versions of std
API functions: isEmpty() on top of empty() and sliced() instead of
subspan(). The (nullary) first()/last() functions (Qt speak for
front()/back()) clash with the std::span function templates of the
same name, so are not provided.

This patch adds QSpan as private API. We intend to make it public API
in the future.

ca6a0fd63f QDTP: match local-time by preference to its zone
When parsing a string whose time-zone part matches local time's name,
use local time in preference to the QTimeZone with that name. The case
is ambiguous, and the bug was already fixed (by something else) in
dev, but this caused a failure in 6.2 through 6.5; and using local
time is more natural to QDateTime in any case. The fix incidentally
makes the the logic of the zone-resolution code more straightforward
and a closer match to how findTimeZone() found the match.

The issue was hidden from 6.6 by a change [*] to the handling of POSIX
rules, that lead to plain abbreviations such as CEST and BST - for
which the IANA DB has no entry - no longer being considered "valid"
zones, despite being technically valid POSIX zone descriptors
(effectively as aliases for UTC).

Although QSystemLocale is (to make its query enum usable) defined
despite the QT_NO_SYSTEMLOCALE define, it's not used in that case, so
tests based on it won't work. So extend the reach of the #if-ery to
include the test using a custom class based on it. Also rename the
test from systemLocale(), as that's the name the emptyCtor() test
really should have.

on the order of test functions, as the name() test function modifies the
