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/.

Because this is misleading:
socket.bind(QHostAddress::AnyIPv4);
The conversion of enum to int has preference over the construction of
QHostAddress from enum, so that ends up calling bind(6), which attempts
to bind to privileged port 6 and just returns with error. Meanwhile,
socket.bind(QHostAddress::AnyIPv4, 0);
does construct the QHostAddress because that is preferred to converting
the int to the BindMode enum.
Ideally we'd simply add the overload to QAbstractSocket but we can't do
that because QHostAddress depends on QAbstractSocket. So I've added a
Qt7 task to invert that dependency.

It works as follows:
- user calls write(const QByteArray &);
- this function keeps a pointer to the chunk and calls a regular
write(data, len);
- write(data, len) calls a virtual writeData();
- subclass calls a new QIODevicePrivate::write();
- QIODevicePrivate::write() makes a shallow copy of
the byte array.
Proposed solution is fully compatible with existing subclasses.
By replacing a call to d->writeBuffer.append() with d->write(),
subclasses can improve their performance.

After calling this function, the user expects that the connection is
terminated, I/O device is closed and the socket is ready for a new
attempt. But, if the socket was disconnected before the call, close()
is not called and I/O device remains opened.
Because QAbstractSocket::close() and QIODevice::close() can handle
reentering, we can call close() unconditionally, which makes
the behavior obvious.

QIODevice::skip() called a virtual QIODevicePrivate::skip() to

QObjectPrivate::threadData used to be a QThreadData *, and was
read and written from multiple threads without proper synchronization.
As an example, it was read from QCoreApplication::postEvent and
written from QObject::moveToThread, therefore causing UB.
Port threadData to a proper atomic, removing the races. Fix all usage
points.
In general, QObject is documented to be simply reentrant,
not thread-safe, and certain bits (e.g. timers, moveToThread)
are not even reentrant. The reasoning therefore is that a given
QObject's threadData is not supposed to be touched by multiple
threads without some synchronization happening elsewhere, and
therefore relaxed loads should be sufficient.
As drive-by change: refactor QCoreApplication::postEvent.
It was particularly subtle, because it had a loop using a volatile
to cope with the possibility of the receiver object switching thread
while we tried to lock its thread's event queue.
However, volatile does not achieve any synchronization, so drop it,
and refactor the algorithm using better locking primitives.
Put this algorithm in a common place, and also reuse it from
removePostedEvents, which was lacking any synchronization.

Using IP addresses does not work for every use case on WinRT. The
workaround that is in place for VPN connections uses the host name
directly but has the disadvantage that it:
1) does a host lookup nevertheless and ends up using the host name
afterwards.
2) needs a set environment variable to be activated.
Instead of doing a host lookup we now use the same approach that is used
if a proxy with the HostNameLookupCapability is present. In this case the
lookup is skipped and the direction is made using the hostname.
The big advantage of hostname over ip addresses on WinRt is, that
Windows handles everything related to lookup and proxies (it uses the
system proxy in this case), so we do not have to take care of that.
As the WinRT backend falls back to the "connectToHostByName" in any
case no further adaptions are needed.
QT_WINRT_USE_THREAD_NETWORK_CONTEXT cannot be completely removed though
