Historic QDateTime behavior when being asked to create a
QDateTime in the DST gap was to interpret the given date
as if it was in the time before that gap, mapping it to a point
in time after the gap. This has changed with
a04411119e .
Since then, the given date is interpreted as if it was in the
time after the gap, thus being mapped to a point in time
before the gap.
This patch restores the historic behavior.
This was not caught by Coin because machines ran in timezone
"Atlantic/Reykjavik" which does not have DST since 1967.
This patch changes tests to always run in "Europe/Oslo".

Technically, having a single constructor limits the use-cases for this
class. We should take into account that:
- an opened socket descriptor must be available at the moment of
construction;
- the constructor unconditionally enables the notifier (the possible
solution
notifier = new QSocketNotifier(...);
notifier->setEnabled(false);
is suboptimal due to heavy operations inside the event dispatcher);
- for these reasons, QSocketNotifier most often cannot be a member of
another class (we have an extra allocation and indirect access).
This patch addresses this shortcoming by making it possible to set the
socket descriptor at a later point:
[ChangeLog][QtCore][QSocketNotifier] Added setSocket() and an additional
constructor which requires no socket.

Because CBOR strings are encoded in UTF-8, it's possible that the string
that won't fit a QString in UTF-16 would still fit QByteArray in UTF-8
(e.g., anything US-ASCII and most Latin text).
The previous solution was an improvement because we used to read into a
QByteArray then convert the QByteArray to QString, thus using 3x the
amount of memory (1x in QByteArray, 2x in QString). The previous commit
skipped the middle allocation and made the regular readString() function
do the decoding either directly on source memory or by reading in small
chunks (16 kB).
Future improvement for Qt 6.1: add readStringChunk(char16_t *, qsizetype)
so we can do the validation / skipping at O(1) memory.

By calling the internal readStringChunk() function with a QByteArray
pointer, QCborStreamReader::readByteArray() can now avoid allocating the
resulting buffer until the internals have confirmed that there is
sufficient data in the incoming buffer. As a result, we first detect the
EOF condition before we conclude the payload would have been too big for
QByteArray (validation()) test. Meanwhile, the hugeDeviceValidation()
test ends up with a few conditions where it would have copied 1 GB of
data, so limit that too.
We make a choice of reporting OOM vs DataTooLarge only if QByteArray
fails to allocate in the first place (QByteArray::resize() ->
Q_CHECK_PTR -> qBadAlloc, QtCore is always built with exceptions on).

std::optional<int> is the wrong datatype to use for compare.
First and foremost, it can't be used in the idiomatic form of
auto r = a.compare(b);
if (r < 0) ~~~ // a is less than b
if (r > 0) ~~~ // a is greater than b
which we *already* feature in Qt (QString, QByteArray).
Also, std::optional<int> (explicitly) converts to bool, which is
a trap, because the result of the comparison can be accidentally
tested as a bool:
if (a.compare(b)) ~~~ // oops! does NOT mean a<b
Not to mention extending this to algorithms:
auto lessThan = [](QVariant a, QVariant b) { return a.compare(b); }; // oops!
std::ranges::sort(vectorOfVariants, lessThan);
which thankfully doesn't compile as is -- std::optional has
an *explicit* operator bool, and the Compare concept requires an
implicit conversion. However, the error the user is going to face
will be "cannot convert to bool because the operator is explicit",
which is deceiving because the fix is NOT supposed to be:
auto lessThan = [](QVariant a, QVariant b) { return (bool)a.compare(b); }; // big oops!
Instead: backport to Qt the required subset of C++20's <compare>
API, and use that. This commits just adds the necessary parts
for compare() (i.e. partial ordering), the rest of <compare>
(classes, functions, conversions) can be added to 6.1.

This was so far problematic as it gave various link errors. The solution
to that seems to be to make the default constructor of QPairVariantInterfaceImpl
constexpr to get around one set of problems.
The other problem to solve where undefined references to metaobjects. The
reason for that is apparently that QMetaTypeInterface contains a direct
pointer to the meta object, something the linker doesn't like. Adding a
level of indirection by using a function that returns the pointer seems
to solve that problem.

- If both progressMinimum() and progressMaximum() return 0, the

std::function as a type is rather unfortunate for us, as its SSO buffer
makes it rather large, and we can ensure that the function is never
empty.
Considering that we do need to allocate memory for
QPropertyBindingPrivate anyway, we can get rid of the SSO buffer and
instead coalesce the allocations (similar to how std::make_shared works).
The memory looks then like
[--QPropertyBindingPrivate--][Functor]
and QPropertyBindingPrivate can get a pointer to the functor via
reinterpret_cast<std::byte>(this)+sizeof(QPropertyBindingPrivate).
To actually do anything with the functor, we do however need a "vtable"
which describes how we can call, destroy and move the functor. This is
done by creating a constexpr struct of function pointers, and storing a
pointer to it in QPropertyBindingPrivate.
As a consequence of those changes, we cannot use QESDP anymore, as we
now have to carefully deallocate the buffer we used for both the
QPropertyBindingPrivate and the functor. We introduce a custom
refcounting pointer for that. While we're at it, we make the refcount
non-atomic, as bindings do not work across threads to begin with.
Moreover, we can now make the class non-virtual, as that was only needed
to hack around limitations of QESDP in the context of exported symbols.

has moved the results from QFuture via QFuture::takeResult() before
trying to do the conversion.
- Disable implicit conversion of QFuture<T> to QFuture<void>, by making
the constructor explicit. If the users really intend to do the
conversion, they should do it explicitly.
[ChangeLog][Source-Incompatible Changes][QFuture] Implicit conversions
of QFuture<T> to T and to QFuture<void> have been disabled. Use
QFuture::result() or QFuture::takeResult() where you need to convert
QFuture<T> to T. Use the explicit QFuture<void>(const QFuture<T> &)
constructor to convert QFuture<T> to QFuture<void>.

So far, the internals of QDateTimeParser and especially the handling
of 'Intermediate' values were only tested implicitly by
tst_qdatetimeedit. 'Intermediate' values are values which
are not valid according to the specified format, but could
become valid by adding more characters.
This patch adds unit tests which tests parsing of
these intermediate values directly.
These tests will help implement handling of negative
year numbers, where additional complications arise
because of possible ambiguities between the minus sign '-'
and the separator '-'.

Requires subsequent re-numbering of the enum tables to eliminate gaps,
before locale data can be regenerated. However, it will work with the
present locale data, since it merely loses the means to use some names
for which the available data was just the name and code. This implies
a transient issue of recognising some codes for which there is no
actual enum member; but relevant code will work as before, finding
nothing but the code and its name. This shall be resolved by a coming
BiC change to resort the language, country and script codes, changing
the numbering (almost) completely.

This reverts commit 1918c689d7.
The template gets always instantiated in QObjectPrivate::connect, even
if the connection types is not Qt::(Blocking)QueuedConnection. For
non-queued connections we however support using incomplete types in
connect. The only way to fix this would be to make the connection type a
template parameter of QObjectPrivate::connect (or at lesat pass some
compile time constant indicating "blocking"-ness) along, so that we can
use if constexpr instead of if. As all involved classes are private, we
can postpone investigating this solution to 6.1

Unlike the 32-bit version, we can't go to a bigger integer type to do
the multiplication with. So instead accept looping. Both libstdc++ and
libc++ implement std::uniform_int_distribution this way anyway, but in a
far more complex way.
There is no looping if the "highest" is a power of two. The worst-case
scenario is when "highest" is one past a power of two (like 65). In that
case, we'll loop until the number is in range. Since all bits have equal
probability of being zero or one, there's a 50-50 chance that the most
significant useful bit will be set[*], in which case we'll need to loop
and we again get the same probability. So on average, we only need two
iterations to get an acceptable result.
[*] There's also a possibility that the other bits are such that the
number is still in range. For 65, we'd need the other 5 bits to be zero
(64 is a valid result), but the probability of that is only 1/2^5 =
3.125%. The bigger "highest" is, the closer we get to zero, so
approximate by saying that never happens and instead calculate that the
most significant useful bit is the controlling one.
[ChangeLog][QtCore][QRandomGenerator] Added 64-bit versions of the
bounded() functions. They are useful in conjunction with Qt 6's 64-bit
container sizes, so code that used to call bounded(list.size()) in Qt 5
will continue to compile and work in Qt 6.
