If CountedStruct is passed a GetSenderObject object,
it will attempt to call a member on it from within
its own destructor.
That works usually quite well, but in this test case,
which tests for function object leaks when a connection
is torn down because the sender object is destroyed,
the destruction of the CountedStruct happens when all
connections are severed in ~QObject. At that point,
what used to be a GetSenderObject instance no longer
is one and the call into one of its member functions
invokes undefined behavior.
Fix by making QObject::sender() public by a using
declaration instead of a wrapper function.

If QObjectPrivate::declarativeData is set, it is
in various places in Qt expected to point to a

In noDeclarativeParentChangedOnDestruction(), the

QAbstractDeclarativeData instance, which, being an
empty class, has size 1 and alignment 1.

When the byte sequence for a BOM occurs in the middle of a utf8 stream,
it is a ZWNBSP.
When a ZWNBSP occurs in the middle of a utf8 character sequence, and the
SIMD conversion does some work (meaning: the length is at least 16
characters long), it would not recognize the fact some charactes were
already decoded. So the conversion would then strip the ZWNBSP out,
thinking it's a BOM.
The non-SIMD conversion did not have this problem: the very first
character conversion would already set the headerdone flag.

To handle network events, QEventDispatcherWin32 uses I/O model
based on notifications through the window message queue. Having
successfully posted notification of a particular event to an
application window, no further messages for that network event
will be posted to the application window until the application
makes the function call that implicitly re-enables notification
of that network event. With these semantics, an application need
not read all available data in response to an FD_READ message:
a single recv in response to each FD_READ message is appropriate.
If an application issues multiple recv calls in response to a
single FD_READ, it can receive multiple FD_READ messages
(including spurious).
To solve this issue, this patch always disables the notifier
after getting a notification, and re-enables it only when the
message queue is empty.

There was a small amount of time between the last readDatagram() call
and disabling a read notifier in case the socket had a pending
datagram. If a new datagram arrived in this period, this qualified as
absence of a datagram reader. Do not change the read notifier state
because it is disabled on canReadNotification() entry and always enabled
by the datagram reader.
Thanks to Peter Seiderer, who investigated the same: "Querying
hasPendingDatagrams() for enabling/disabling setReadNotificationEnabled()
is racy (a new datagram could arrive after readDatagam() is called and
before hasPendingDatagrams() is checked). But for unbuffered sockets the
ReadNotification is already disabled before the readReady signal is
emitted and should be re-enabled when calling read() or readDatagram()
from the user."
However, this patch does not completely solve the problem under Windows,
as the socket notifier may emit spurious notifications.

QString subject("Miss");

Instead, actually adjust the pointer to the subject string so that
