Fixes failure to find qHash functions when building Squish. Here, QMap
is used with custom types that do not have any associated qHash
functions. It should therefore not require a qHash function to be
usable with QMap.
There is no indication in the build output where the instantiation came from. There's nothing in the output about the function it should have
called, likely because no qHash functions exists.

Found in API review, but not deemed important enough to still get into
6.7.
Not implementing it for QMultiMap, because there we need to mod out
order of equivalent elements.
The GHS compiler acted up and tried to compile the noexcept
specification, hitting non-existing qHash(QVariant) for QVariantMap
and producing a hard error instead of SFINAE'ing out. As a
work-around, establish an artificial SFINAE-friendly context, but only
for that compiler.
[ChangeLog][QtCore][QMap/QHash] Added qHash() overload for QMap.

To allow the user to customize the C++ code that QDoc sees, so as to be
able to work-around some limitations on QDoc itself, QDoc defines two
symbols: Q_QDOC and Q_CLANG_QDOC, both of which are "true" during an
entire execution of QDoc.
At a certain point in time, QDoc allowed the user the choice between a
custom C++ parser and a Clang based one.
The Q_QDOC symbol would always be defined while the Q_CLANG_QDOC symbol
would be defined only when the Clang based parser was chosen.
In more recent times, QDoc always uses a Clang based parser, such that
both Q_CLANG_QDOC and Q_QDOC are always defined, making them equivalent.
To avoid using different symbols, and the possible confusion and
fragmentation that derives from it, all usages of Q_CLANG_QDOC are now
replaced by the equivalent usages of Q_QDOC.

Our associative containers' iterator's value_type isn't a destructurable
type (yielding key/value). This means that something like
for (auto [k, v] : map)
doesn't even compile -- one can only "directly" iterate on the
values. For quite some time we've had QKeyValueIterator to allow
key/value iteration, but then one had to resort to a "traditional" for
loop:
for (auto i = map.keyValueBegin(), e = keyValueEnd(); i!=e; ++i)
This can be easily packaged in an adaptor class, which is what this
commmit does, thereby offering a C++17-compatible way to obtain
key/value iteration over associative containers.
Something possibly peculiar is the fact that the range so obtained is
a range of pairs of references -- not a range of references to pairs.
But that's easily explained by the fact that we have no pairs to build
references to; hence,
for (auto &[k, v] : map.asKeyValueRange())
doesn't compile (lvalue reference doesn't bind to prvalue pair).
Instead, both of these compile:
for (auto [k, v] : map.asKeyValueRange())
for (auto &&[k, v] : map.asKeyValueRange())
and in *both* cases one gets references to the keys/values in the map.
If the map is non-const, the reference to the value is mutable.
Last but not least, implement pinning for rvalue containers.

qSwap() is a monster that looks for ADL overloads of swap() and also
detects the noexcept of the wrapped swap() function, so it should only
be used when the argument type is unknown. In the vast majority of
cases, the type is known to be efficiently std::swap()able or to have
a member-swap. Call either of these.
For the common case of pointer types, circumvent the expensive trait
checks on std::swap() by providing a hand-rolled qt_ptr_swap()
template, the advantage being that it can be unconditionally noexcept,
removing all type traits instantiations. Don't document it, otherwise
we'd be unable to pick it to 6.2.
Effects on Clang -ftime-trace of a PCH'ed libQt6Gui.so build:

**** Template sets that took longest to instantiate:
[...]

Q(Multi)Map mutating functions that take reference to a key and/or a
value (e.g. insert(), take(), etc.) must make sure that those references
are still valid -- that is, that the referred objects are still alive --
after the detach() call done inside those functions.
In fact, if the key/value are references into *this, one must take extra
steps in order to preserve them across the detach().
Consider the scenario where one has two shallow copies of QMap, each
accessed by a different thread, and each thread calls a mutating
function on its copy, using a reference into the map (e.g.
map.take(map.firstKey())). Let's call the shared payload of this QMap
SP, with its refcount of 2; it's important to note that the argument
(call it A) passed to the mutating function belongs to SP.
Each thread may then find the reference count to be different than 1 and
therefore do a detach() from inside the mutating function. Then this
could happen:
Thread 1: Thread 2:
detach() detach()
SP refcount != 1 => true SP refcount != 1 => true
deep copy from SP deep copy from SP
ref() the new copy ref() the new copy
SP.deref() => 1 => don't dealloc SP
set the new copy as payload
SP.deref() => 0 => dealloc SP
set the new copy as payload
use A to access the new copy use A to access the new copy
The order of ref()/deref() SP and the new copy in each thread doesn't
really matter here. What really matters is that SP has been destroyed
and that means A is a danging reference.
Fix this by keeping SP alive in the mutating functions before doing a
detach(). This can simply be realized by taking a local copy of the map
from within such functions.
remove() doesn't suffer from this because its implementation doesn't do
a bare detach() but something slightly smarter.

The operator checks cause compilation errors when trying to check for
their existence for recursive containers. This happens because of trying
to check for the operators on the template parameter type(s), that
inherit from the container itself, which leads to compilation errors.
Introduced alternative versions of the operator checks (with _container
suffix), that first check if the container is recursive, i.e. any of its
template parameter types inherits from the given container, and skips
the operator check, if that's the case.
The fix is done for all Qt container types that had the problem, except
for QVarLengthArray and QContiguousCache, which don't compile with
recursive parameter types for unrelated reasons.

We missed the chance of deprecating them in 5.15, so
they'll just add to the pain of porting to 6.0. We
should not keep them around forever, though; QMap isn't

The insert() overloads that took a const_iterator started by calling
std::distance(begin(), pos) - which has a cost linear in how far pos
is from begin() - in order to, after detach()ing, obtain an iterator
at the same offset from the new begin(), using std::next() - also
linear. This leads to quadratic behavior when large numbers of entries
are added with constEnd() as the hint, which happened to be tested by
tst_bench_qmap. That wasn't running, due to some assertion failures,
but once those were fixed the hinted tests timed out after five
minutes, where their unhinted peers completed comfortably within a
second.
Check whether detach() is even needed and bypass the std::distance() /
std::next() linear delay when it isn't. This brings the hinted tests
down to running faster than their unhinted equivalents.

Types that throw in their destructors are strongly discouraged in C++,
and even the STL doesn't define what happens if such types are stored
in their containers.
Make this more explicit for Qt and disallow storing those types in our
containers. This will hopefully preempty any potential future bug
reports about us not handling such a case. It also helps simplify
some code in QList and other cases and makes it possible to explicitly
mark more methods as noexcept.
Some care needs to be taken where to add the static asserts, so that
we don't disallow forward declarations of types stored in containers.
Place the static assert into the destructor of the container where
possible or otherwise into the templated d-pointer.

These containers have most of their operators as non-members,
except those declared as hidden friends in the iterator classes,
which will be fixed in qdoc.
QMultiMap doesn't have an operator[] (which might be unintentional).
Deprecate QMultiMap::insert/insertMulti APIs, as the documentation
suggests that those are just compatibility overloads.
Add documentation for the rvalue-overload of QMap/QMultiMap::insert.
Note that this overload does not exist for QHash/QMultiHash. Also,
it seems from the implementation that the moved-from map is not reset
to the empty map if it did share data with another copy.
Not addressed: QMap and QMultiMap have the special 5 implicitly
generated by the compiler, so these functions are not declared
anywhere, which results in qdoc warnings. qdoc could generate the
documentation automatically, if it can know that those members exist.

1) Implementing the const version in terms of the non-const
version exposes to accidental detaches. Avoid that.
2) The non-const version has to detach, just like find(Key),
or doing a comparison like find(Key, T) != end() might report
a wrong result.
3) Properly check if the value was found by checking find_if's
return value (against its second parameter, the end of the
iterated range). If the value was NOT found, then return
the map's end() (again because clients of find() will check
against end()).

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.

... 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

This had already been in very few places, where we ran into issues with
this before. More generic constraints here will significantly reduce the
amount of error messages a user has to parse in case he tries to instantiate
an operator by accident (or with a lacking comparison operator for one of
it's template arguments).

Containers often define an operator==() or operator<() which is very useful
for generic code. But those operators can usually not be instantiated if
the template argument doesn't implement the operator.
This sometimes leads to the compiler trying all possible template expansions
and implicit conversions for the type, giving extremely long error
messages. The traits support can be used to safely constrain those
operators.
Being able to safely detect this will also allow us to fold the comparison
support that is currently a large cludge for user types directly into
QMetaType.

... it breaks move semantics.
We can change these, since they're templates and a short survey shows
that no-one in Qt was crazy enough to inherit an exported class from
QHash or QMap.
Otherwise this would be BiC on MSVC, which encodes the return type.
There's also no safety benefit here, as none of the overloads returns
by reference, so users cannot expect map.value(key).mutate() to have
an effect on the element in the container.
In this, key() and value() differ from op[], which also returns const,
but whose overload returns a reference. op[] is therefore not proposed
here.
[ChangeLog][QtCore][QHash/QMultiHash/QMap/QMultiMap] The value() and
key() member functions now return T (was: const T), enabling move
semantics on their return values.

for duplicating \fn docs between the base and deriving classes.

- QMultiMap: unite() and one overload of insert() were not recognized
because their definitions in the same header file interfered with
QDoc - use Q_CLANG_QDOC macro to comment them out, and tag \fn
comments to ensure that the function documentation is matched.

insertMulti and unite will silently transform a QMap into a multi-map
which is not behavior we want to keep around anymore and as such is
being deprecated. QMap functions that only make sense in a multi-map
scenario are also deprecated and the implementation is moved to
QMultiMap where it makes sense.
Use QMultiMap if multiple keys are desired and insert(const QMap &)
if a non multi-map-converting unite is desired.
[ChangeLog][QtCore][QMap] insertMulti(), unite(), values(Key),
uniqueKeys(), count(Key) is now deprecated. Please use
QMultiMap instead.

The concept was a nice idea to avoid accidental detach() calls
in implicitly shared containers, but it conflicts with a C++11
compatible API for them, with signatures for modifying methods
taking a const_iterator as argument and returning an iterator
(e.g. iterator erase(const_iterator)).

The macro is not documented, so not part of the public Qt API. It is
made obsolete by the alignof keyword in C++11.
Remove the usage of the macro across qtbase, in particular the
workarounds for compilers that didn't support alignof, and that will
not be supported in Qt 6.
The macro definition is left in place, no need to break existing
code.
