Remove most type traits from qtypetraits.h, but keep the custom
implementation of is_signed/is_unsigned. This gets rid of
BSD-3 licensed code from Google in a public header (hugh!).
The custom implementations for is_signed/is_unsigned are kept
because the implementations in gcc's standard headers do not
work as we expect for enums - both is_signed and is_unsigned
always returns false there - see also
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59027
[ChangeLog][QtCore][General] Qt now relies on type traits from
the C++ standard library.

The Qt::ISODate format strips milliseconds, so a new format is introduced
that keeps the milliseconds. A new format was chosen over fixing the
existing format due to the behavioral change of suddenly having ms
as part of Qt::ISODate.

CFAbsoluteTime is measured in seconds, represented by a double,
so when converting milliseconds to CFAbsoluteTime we may get a
slight error due to missing precision in double to represent
the milliseconds exactly. By rounding to the closest millisecond
when converting back, we avoid truncating and being one ms off.

Costs only ~300B in text size in QtCore, which is roughly compensated by
savings in other QtBase libraries, even without specifically porting
users to QL1S.
Of course, the raison d'être for this overload is avoiding the expensive
QLatin1String -> QString conversion which, for small lists, can take up
to 50% of the total runtime (assuming memory allocations dominate over
scanning and copying the list).

with a useless str.unicode(), which is the actual problem here;
whereas !str.isNull() does really confirm that str.unicode()
is sensible.
Such test prevents situation like:
const QString a;
QString b;
b.append(a); // b.isNull() == true
b.append(QStringRef(&a)); // b.isNull() == false
Auto test updated: create QStringRef from QString directly, without

The hash function is carefully designed to give the same result
as the straight-forward implementation of qHash(unordered_map),
which we'll probably add at some point, namely: std::accumulate
over a container of std::pair.
This is one reason to use std:: and not QPair in the implemen-
tation of qHash(QHash). The other is that qHash(QPair) uses a
bad hash combiner, which may xor out the 'seed' from the result.
We can't fix that until Qt 6, but the qHash(std::pair) overload
uses the well-known boost::hash_combine algorithm (implemented
in Qt as QtPrivate::QHashCombine), so we can use that.
I also trust std::pair to work without problems with reference
template arguments, while QPair only very recently gained a very
basic auto-test for reference parameters.
[ChangeLog][QtCore] Added qHash() overloads for QHash, QMultiHash.

When replacing each copy of one text with a copy of another, we do so
in batches of 1024; if we get more than one batch, we need to keep a
copy of the sought text and replacement if they're part of the string
we're modifying, for use in later batches.
Also do the replacements in full batches of 1024, not 1023 (which left
the last entry in an array unused); marked some related tests as
(un)likely; and move some repeated code out into a pair of little
local functions to save duplcation.
Those new functions can also serve replace_helper(); and it can shed a
const_cast and some conditioning of free() by using them the same way
replace() now does. (There was also one place it still used the raw
after, rather than the replacement copy; which could have produced
errors if memcpy were to exercise its right to assume no overlap in
arrays. This error is what prompted me to notice all of the above.)
Added tests. The last error proved untestable as my memcpy is in fact
as fussy as memmove. The first two tests added were attempts to get a
failure out of it. The third did get a failure, but also tripped over
the problem in replace() itself. Added to an existing test function
and renamed it to generally cover extra tests for replace.
