V4 JIT: fix JS stack frame size calculation.

StackLayout::calculateJSStackFrameSize now returns the size in number
of QV4::Value items, instead of bytes. The value is then multiplied in
the assembler by sizeof(Value) to get the number of bytes. Previously,

It also won't retain objects whose reference accidentally ended up on

Fix fbo creation and resize logic in QQuickWidget

This corrects two issues:

1. Recreating the fbo twice when the widget is shown. Calling
createFramebufferObject() is not necessary in this case since createContext()
will trigger this anyhow due to scenegraphInitialized().

2. Avoid recreating the fbo when the size is the same as before. Some platforms
are keen on sending resize events with the same size. These should be ignored.
What's worse, some platforms (cocoa) generate a resize on exitting (Cmd-Q)
and not ignoring the resize at that stage is dangerous since the scenegraph
is already invalidated.

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.

also increases/decreases the reference count accordingly.

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.
