Fix interaction of garbage collector with JS objects during QML type instantiation

It may happen that during the lengthy process of instantiating a tree of
objects for QML, the garbage collector runs.

For objects created by QML we support different ownership models, for example
in QtQuick visual parents keep their visual children alive, despite perhaps a
lack of QObject parentship. That ownership becomes active once the QML
autoparent function has assigned the correct visual parent, which happens after
object instantiation (after QQmlObjectCreator).

Similarly when a composite type is created, its QObject parent is only set
after all properties have been set. The root QObject is kept alive through a
special boolean, but if the sub-objects aren't children yet, their JS wrapper
might get deleted. For composite types with var properties, that also means
their var properties get deleted, such as the model property of TableView.qml
in the bug report.

In the future we want to support creating QWidget hierarchies with QML, which
also for layouts may rely on a delayed parent assignment for layouts.

To accommodate all this, this patch introduces an array on the JS stack that
keeps track of all JS wrappers for all QObjects created. This array is alive
during object tree creation. Afterwards, the different ownership models take
over, for example the auto parent function assigning a visual parent.

This patch also fixes an off-by-one in the total object count calculation
for composite types, where when instantiating a composite type as a sub-object
we counted the sub composite's object count but forgot the object itself.

Use QSignalSpy instead of waitFor in tst_qpacketprotocol

QTcpServer::waitForNewConnection() blocks the event loop and prevents
the client, that runs in the same event loop, from sending anything.
Also, if the connection is established before waitForNewConnection() is
called we're going to wait for another connection, which will never
happen.

It's not clear if this is actually the cause of the test failures but
blocking the event loop is generally a bad idea and the last change to
the test that actually made a difference to the functionality added
exactly that line, see b36bbe3626bc68ac267d7653fa6408a8f258251d.

Fix bindings to when property of States not always working

Fix method overload calling of Qt slots from JavaScript

After commit ac57f185d1a2203cd4b585df7bd7af01c3ec33ed we succeed in selecting
the correct overload based on the supplied arguments. However when calling
slots on objects without a property cache, we end up using the local "dummy"
variable to store the synthetic propert data. We also store the currently best
patch in the "best" variable, which is a _pointer_ to the property data of the
match. Suppose we have 5 overloads to choose from, we find that the 3rd is
the best. Then we try the fourth but find it unsufficient and break out of
the loop. Unfortunately the "dummy" property data at this point contains the
data of the fourth (wrong) overload, and our best match variable points to it.
So then when we finally call the method, we do it based on the wrong property
data.

The easy patch is to simply copy the few bytes of property data, so "best" is
stored by value instead of pointer.
