Just like any other container, it's legitimate for the user to
pass key/values belonging to the same container.
Q(Multi)Map::remove(Key) are already safe (either they call
erase() directly on std::(multi)map, where it does the right thing,
or they skip elements while detaching).
However, QMultiMap::remove(Key, T) wasn't safe in this regard
(the implementation is hand rolled), so take copies before start
erasing.

Refactored certain bits of qarraydataops.h: picked exception-related

Personally, the existing code seemed rather complicated to analyze

at the whole thing for a while or "returning back" from some other work
and I still have my doubts that everything works correctly. Testing the
building blocks that are used should:
a) increase trust into existing code (provided the usage is correct)
b) give more use cases of how to use the building blocks, which in turn
would allow to compare and contrast tests vs implementation

After reimplementing Qt JSON support on top of CBOR, there were
unintended behavior changes when converting QVariant{, List, Map} to
QJson{Value, Array, List} due to reusing the code for converting
QVariant* types to CBOR types, and from CBOR types to corresponding JSON
types. In particular, conversions from QVariant containing QByteArray to
JSON has been affected: according to RFC 7049, when converting from
CBOR to JSON, raw byte array data must be encoded in base64url when
converting to a JSON string. As a result QVariant* types containing
QByteArray data ended up base64url-encoded when converted to JSON,
instead of converting using QString::fromUtf8() as before.
There were also differences when converting QRegularExpression.
Reverted the behavior changes by adding a flag to internal methods for
converting CBOR to JSON, to distinguish whether the conversion is done
from QVariant* or CBOR types. These methods now will fall back to the old
behavior, if the conversion is done using QJson*::fromVariant*().
Additionally fixed QJsonValue::fromVariant conversion for NaN and
infinities: they should always convert to QJsonValue::Null. This works
correctly when converting from variant to QJsonArray/QJsonObject, but has
been wrong for QJsonValue.
Added more tests to verify the expected behavior.
[ChangeLog][Important Behavior Changes] Restored pre-5.15.0 behavior
when converting from QVariant* to QJson* types. Unforeseen consequences
of changes in 5.15.0 caused QByteArray data to be base64url-encoded; the
handling of QRegularExpression was also unintentionally changed. These
conversions are now reverted to the prior behavior. Additionally fixed
QJsonValue::fromVariant conversions for NaN and infinities: they should
always convert to QJsonValue::Null.

for some corner cases and when using our internal API.

mkspecs/features/qt.prf adds a dependency on the system threading
library if the Qt Core thread feature is enabled. Because qt.prf is
loaded by any public or internal Qt project, it's essentially a public
dependency for any Qt consumer.
To mimic that in CMake, we check if the thread feature is enabled, and
and set the Threads::Threads library as a dependency of Qt6::Platform,
which is a public target used by all Qt modules and plugins and Qt
consumers.
We also need to create a Qt6Dependencies.cmake file so we
find_package(Threads) every time find_package(Qt6) is called.
For the .prl files to be usable, we have to filter out some
CMake implementation specific directory separator tokens
'CMAKE_DIRECTORY_ID_SEP' aka '::@', which are added because we call
target_link_libraries() with a target created in a different scope
(I think).
As a result of this change, we shouldn't have to hardcode
Threads::Threads in other projects, because it's now a global public

* drop QT_STRICT_ITERATORS;
* iterators implictly convert to const_iterators, and APIs
take const_iterators;
* iterators are just bidirectional and not random access;
* added noexcept where it makes sense;
* "inline" dropped (churn);
* qMapLessThanKey dropped (undocumented, 0 hits in Qt, 1 hit in KDE);
* operator== on Q(Multi)Map requires operator== on the key type
