We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.
Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

Commit 35adb74ddd ("Reimplement JSON
support on top of Cbor") accidentally forgot to multiply by 2 the index
stored in the QJsonObject::iterator. The same mistake was propagated
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.
Drive-by modernization of some of the surrounding lines.

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
Says Clang 10:
tst_qtjson.cpp:990:5: warning: ISO C++20 considers use of overloaded operator '==' (with operand types 'QJsonValueRef' and 'QJsonValueRef') to be ambiguous despite there being a unique best viable function [-Wambiguous-reversed-operator]

qjsonvalue.h:189:17: note: ambiguity is between a regular call to this operator and a call with the argument order reversed

A similar argument makes op!= ambiguous.
Says Clang 10:

To fix, provide the missing operators as free inline functions (so Qt
6.2 and 5.15 don't get new symbols added) so there's always exactly
one best match.
This is a fix for 6.2 and 5.15. At the time of writing, 6.3 isn't
released, yet, so there, we could QT_REMOVED_SINCE the pre-existing
member operators in favor of hidden friends (as per QTBUG-87973).

QChar should not be convertible from any integral type except from
char16_t, short and possibly char (since it's a direct superset).
David provided the perfect example:
if (str == 123) { ~~~ }
compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.
Add a macro to revert to the implicit constructors, for backwards
compatibility.
The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.

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.
