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.

The existing API of QFlatMap did not allow efficient removal of
elements:
- std::remove_if does not apply, because it works by moving elements
back in the range onto those that need to be removed, which doesn't
work in flat_map's case, because, like for all associative
containers, the key in value_type is const.
- The node-based erase-loop (over it = cond ? c.erase(it) :
std::next(it)) works, but, unlike in traditional associative
containers, is quadratic, because flat_map::erase is a linear
operation.
According to Stepanov's principle of Efficient Computational Basis
(Elements of Programming, Section 1.4), we're therefore missing API.
Add it.
I couldn't make up my mind about the calling convention for the
predicate and, despite having authored a merged paper about erase_if,
can never remember what the predicate is supposed to take, so be fancy
and accept all: (*it), (it.key(), it.value()), (it.key()). This means
that unary predicates can either not be generic or must be properly
constrained to distinguish between pair<const K, V> and K, but that's
not necessarily a bad thing.
There's no reason to supply a Qt-ified removeIf on top of the standard
name, because this is private API and doubling the names would do
nothing except double the testing overhead.

when QJsonObject::iterator was converted to QJsonValueRef. This had no
ill effects because the o->elements container would always contain more
elements, but it meant the check was ineffective and meant nothing.
So instead of doing nothing when the iterator does not point to this
container, simply assume it does. Bad things will happen if you try to
erase an iterator that points to another container, but that's true for
almost all container/iterator mechanisms.

In C++20, any given relational operator is also considered in its
reversed form, so e.g.
given op==(X, Y)
and X x, Y y, then y == x will compile, by using the reversed op(X, Y)
This, unfortunately, makes some existing asymmetric operator overload
sets ambiguous, and instead of applying tie-breaker rules, at least
Clang is warning about these.
For us, this means we need to make our overload set non-ambiguous. The
QJsonValue{,Ref} classes failed this, because they only provide the
following member-operators:
- QJsonValue::op==(const QJsonValue&) const
- QJsonValueRef::op==(const QJsonValue &) const
For member functions, there are no implicit conversions on the LHS. So
in C++17, we have a nice dichotomous overload set:
- LHS is QJsonValue -> use QJsonValue::op==(QJsonValue)
- LHS is QJsonValueRef -> use QJsonValueRef::op==(QJsonValue)
In both of these, it the RHS is a QJsonValueRef, it's implicitly
converted to QJsonValue for the call.
Enter C++20, and the reversed signatures are suddenly available, too,
which is a problem for QJsonValueRef <> QJsonValueRef, which could be
resolved, as in C++17, using
lhs.QJVR::op==(QJV(rhs))
or it could now be
rhs.QJVR::op==(QJV(lhs)); // reversed

To fix, provide the missing operators as free inline functions (so Qt

one best match.
This is a fix for 6.2 and 5.15. At the time of writing, 6.3 isn't
