b7fc75c883 qt: Use a proxy object for access to the QML widget
QML can destroy the video widget at any time, leaving
us with a dangling pointer. Use a lock and a proxy
object to cope with that, and block in the widget
destructor if there are ongoing calls into the widget.

afae1c53d2 qml/item: also unref the display on destruction
Leaking objects (and a thread!) is never a good idea.

ba69afdc47 qmlglsink: add win32 support
The current state of c++ ABI's on Window's and Gst's/Qt's conflicting
mingw builds means that we cannot use mingw for building the qt plugin.

Instead, a qmake .pro file is provided that is expected to be used with the
msvc binaries provided by Qt like so:

(with the PATH environment variable containing the path to the qt biniaries
and PKG_CONFIG_PATH containing the path to GStreamer modules)
cd /path/to/sources/gst-plugins-bad/ext/qt
qmake -tp vc

Then open the resulting VS project and build the library.  Then

cp debug/libgstqtsink.dll /path/to/prefix/lib/gstreamer-1.0/libgstqtsink.cll

to get wayland display for QT.

c086540291 qt: use a static_cast instead of dynamic one
The dynamic_cast is a little but of overkill as the app will still crash if it
fails in the later g_assert.

Allows compilation with -fno-rtti

27c94f3375 qml: proper initialization if scene is already initialized
The scene graph can be initialized when the we receive window handle change
notification and so we will not receive a scenegraph initialization
notification.  Initialize ourself in this case.

769fffa3d9 new qt5 qml GL video sink
Very much in the same spirit as the Gtk GL sink

Two things are provided
1. A QQuickItem subclass that renders out RGBA filled GstGLMemory
   buffers that is instantiated from qml.
2. A sink element that will push buffers into (1)

To use
1. Declare the GstGLVideoItem in qml with an appropriate
   objectName property set.
2. Get the aforementioned GstGLVideoItem from qml using something like

QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

QObject *rootObject = engine.rootObjects().first();
QQuickItem *videoItem = rootObject->findChild<QQuickItem *> ("videoItem");

3. Set the videoItem on the sink
