isNull() would forward to the contained type and check that type's
isNull() method for some of the builtin types. Remove that behavior
and only return true in isNull(), if the variant is invalid, doesn't
contain data or contains a null pointer.
In addition, implement more consistent behavior when constructing
a QVariant using the internal API taking a copy from a void *.
isNull() should return true in both cases. This mainly changes behavior
for some corner cases and when using our internal API.
[ChangeLog][Important Behavior Changes] QVariant::isNull()
no longer returns true when the variant contains an object of some
type with an isNull() method, that returns true for the object;
QVariant::isNull() now only returns true when the variant contains
no object or a null pointer.

Comparing two variants will not try to convert the types
of the variant anymore. Exceptions are when both types are
numeric types or one type is numeric and the other one a
QString. The exceptions are there to keep compatibility with
C++ and to not completely break QSettings (which needs automatic
conversions from QString to numeric types).
[ChangeLog][Important Behavior Changes] Comparing two
variants in Qt 6 will not try attempt any type conversions before
comparing the variants anymore. Instead variants of different type
will not compare equal, with two exceptions: If both types are numeric
types they will get compared according to C++ type promotion rules. If
one type is a QString and the other type a numeric type, a conversion
from the string to the numeric tpye will be attempted.

[ChangeLog][Important Behavior Changes][QVariant] QVariant will now use builtin support in
QMetaType to compare its content. This implies a behavioral change
for some graphical types like QPixmap, QImage and QIcon that will

operator).

... and QMultiMap as std::multimap.
Just use the implementation from the STL; we can't really claim that
our code is much better than STL's, or does things any differently
(de facto they're both red-black trees).
Decouple QMultiMap from QMap, by making it NOT inherit from
QMap any longer. This completes the deprecation started in 5.15:
QMap now does not store duplicated keys any more.
Something to establish is where to put the
QExplictlySharedDataPointer replcement that is in there as an
ad-hoc solution. There's a number of patches in-flight by Marc
that try to introduce the same (or very similar) functionality.
Miscellanea changes to the Q(Multi)Map code itself:
* consistently use size_type instead of int;
* pass iterators by value;
* 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
(we're checking for equality, not equivalence!).
Very few breakages occur in qtbase.
[ChangeLog][Potentially Source-Incompatible Changes] QMap does not
support multiple equivalent keys any more. Any related functionality
has been removed from QMap, following the deprecation that happened
in Qt 5.15. Use QMultiMap for this use case.
[ChangeLog][Potentially Source-Incompatible Changes] QMap and
QMultiMap iterators random-access API have been removed. Note that
the iterators have always been just bidirectional; moving
an iterator by N positions can still be achieved using std::next
or std::advance, at the same cost as before (O(N)).
[ChangeLog][Potentially Source-Incompatible Changes] QMultiMap does
not inherit from QMap any more. Amongst other things, this means
that iterators on a QMultiMap now belong to the QMultiMap class
(and not to the QMap class); new Java iterators have been added.

QSet and std::(unordered_)set were so far not treated as appendable, as

We achieve this by testing for and using the insert method. While vector

position or iterator + value, so the template specialization is not
ambiguous.

This pulls the CMake port, which not only adds CMake files but also
modifies existing code. A brief summary of "seemingly unrelated" changes:
* configure.json was re-formatted to not use multi-line strings. That
is an extension of the Qt JSON parser but not JSON compliant, which
is needed for the configure.json-to-cmake conversion script (python).
* Some moc inclusions were added due to CMake's slightly different way
of handling moc. With the changes the files build with qmake and cmake.
* Since CMake just grep's for the Q_OBJECT macro to determine whether to
call moc (instead of doing pre-processing like qmake), the existing use
of "Q_OBJECT" in our documentation was changed to \Q_OBJECT, which cmake
doesn't see and which is now a qdoc macro.
* QTestLib's qFindTestData was extended to also search in the source
directory known at build time.
What this change also brings is a new way of building modules in Coin by using
YAML configuration files that describe the steps of building and testing in Coin
specific terms. The platform configuration files in qt5 are instructed to use the
old Coin built-in way of testing ("UseLegacyInstructions" feature) but for any
configurations that do not have this, these yaml files in the coin/ sub-directory
are used and shared across repositories.
