Some time ago, we spent a lot of time fine-tuning the behavior of
indexOf() and split() w.r.t. matching of empty needles, or in empty
haystacks. Make sure that (QByteArray) replace() is behaving
consistently.
It isn't. Filed QTBUG-134079 to track the issue.

Coverity complains that qCountLeadingZeroBits() may return 64 and then
the RHS will be out-of-range for int. Of course, 64 leading zero bits
means that the argument is 0, which we excluded in the first `if` of
the if-else chain.
I can only guess (because it doesn't tell me which value of `bytes` it
is using for the analysis) that Coverity assumes bytes ==
numeric_limits<qint64>::min() and considers the overflow in qAbs() to
yield a 0, because, it being UB, it may yield anything.
Be that as it may, the fact remains that formattedDataSize() invokes
UB when passed numeric_limits<qint64>::min(), as confirmed by ubsan:
global/qnumeric.h:479:26: runtime error: negation of -9223372036854775808 cannot be represented in type 'long long int'; cast to an unsigned type to negate this value to itself

So fix the overflow by using the new QtPrivate::qUnsignedAbs(). Then
sit back and await Coverity's verdict on the next run.

QAnyStringView is designed to replace overload sets containing QString
and QChar, among others, so it needs to accept types that merely
implicitly convert to QString and QChar. It achieves this by
maintaining a hidden container to hold the converted QString or QChar
for the duration of the full-expression, much like the compiler would
do if the function took QString/QChar.
This patch adds a check for the single-char ctors to determine whether
they convert or not, by comparing QASV::data() to the address of the
QASV's argument. While it would be interesting to have the same test
for QString, that is outside the scope of this patch.

We were including, for each entry we got from CLDR or the system,
minimal and maximal additions from CLDR's likely-subtag rules, plus
versions with script omitted and possibly also territory added, when
likely-equivalent to the original. Include also the converse, with
territory omitted and possibly also script added when
likely-equivalent, so as to control order when these entries also show
up by truncation of others.
The pick to 6.8 was bound to get conflicts and is really a back-port
of reasonably future-compatible behavior to the 6.8 code-base. Results
from uiLanguages() itself are not the same as in 6.9 - truncations are
not included, because QTranslator takes care of those. It includes,

The QtDeclarative code causing QTBUG-131906 hits UB, because it tries
to store -666 in an enum {A, B}, which has a valid range of [0,1],
therefore its underlying_type is uint, yet, as per [conv.prom]/3¹,
integer-promotes to _int_ instead, so in Qt 6.8 would cause the
arg(int) overload to be called, outputting -666, while in Qt 6.9, it's
treated (correctly) as an unsigned value, outputting -666's two's
complement, a positive value.

The original idea (8b5aa7b6c4) of the
separation of array and pointer ctors was to determine string literal
sizes at compile-time in C++11's limited constexpr semantics.
But when the scanning for NUL characters was added to the array ctor
in 107ff4c1d6, the distinction between
the two ctors became meaningless, because we were able to assume
post-C++11 constexpr to make the Char(0) scan a compile-time action.
Finally, 9e1dc1e8a9 removed the array
ctor in favor of the generic Container ctor. I didn't check whether
the old code handled arrays of unknown size, as in
extern const char16_t str[];
QStringView sv = str;
~~~
const char16_t str[] = "str";
but std::size() (and therefore if_compatible_container) surely bails
on such arrays, and if_compatible_pointer also SFINAEs out. As a
consequence, such arrays cannot be used to construct QStringViews atm.
Fix by adding a new constructor for arrays of unknown size, delegating
to the existing pointer overload.
The GHS compiler doesn't like the CanConvert static_asserts, so
comment them out for it. The functionality itself is tested by

We do have an implicit constructor which allows construction of a
QLocale from the QLocale::Language enum values. It will be used when
doing the comparison.
However, do not rely on the implicit conversions, and provide the
operators that explicitly do the right thing. This also allows us to
save an extra allocation of QLocalePrivate.

As a drive-by: fix the order of the test slots in the unit test.

They were lacking it since the start of the public history, and
porting to std::snprintf() (which has the warning) as part of making
Qt compile with QT_NO_SNPRINTF has turned up surprisingly many
-Wformat warnings, so enable the warning for the remaining (non-tree)
users.
Backporting aggressively, as this might unearth security bugs in user
code.
[ChangeLog][QtCore][q(v)snprintf] Added attributes for GCC-compatible
compilers to detect format/argument mismatches. If this throws warnings
for your calls now, don't ignore them. printf() format mistakes could
be security-relevant. You may also find that you relied on undocumented
behavior, such as that certain implementations (Windows, Android, WASM)
of qsnprintf() support char16_t* instead of wchar_t* for %ls. In that
case, you should port to qUtf16Printable() and QString::asprintf(), or
suppress the warning and port away from the platform dependence at your
earliest convenience.

The "many-0 max dec" tests check if a large number (512) of leading zeros
interferes with parsing the number.
The std::from_chars implementation available on VxWorks cannot handle
strings longer than 255 characters.
The number is properly parsed, but the ptr returned as a part of the
std::from_chars_result does not contain the correct result.
It should point to the end of the string (as there is nothing left after the
number), but it wraps and starts to point to other places.
This leads to a wrong value returned by qstrnto(u)ll and to a failing
test.
The issue has been acknowledged by WindRiver. For now, blacklist the
"many-0 max dec" tests.

Strictly speaking, we did want to compare pointers, but char* are
special with QCOMPARE in that the pointed-to strings are compared, not
the pointers. So this wasn't doing what we wanted it to do.
We could static_cast to void* to do it, but subtracting one from the
other also gets us what we want, with simpler code. The drawback is that
if appendToBuffer() ever returns nullptr, we'll print a huge number as
the offset.
