0e6a8838dc qtsink: Add configured GL cflags to the build 
We don't directly link to GL in the element, though we use GL headers.
For this reason we need to include the proper GL headers path. This
prevent this element from using a different GL header then libgstgl.

28d088fa2d glmemory: base classify and add the pbo memory on top 
The base class is useful for having multiple backing memory types other
than the default.  e.g. IOSurface, EGLImage, dmabuf?

The PBO transfer logic is now inside GstGLMemoryPBO which uses GstGLBuffer
to manage the PBO memory.

This also moves the format utility functions into their own file.

21ca4ac9d3 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.

5f8a587ddc qt: don't use CPPFLAGS for tools that cannot use them 
For example moc will bail out when given arguments it does not
know about.  The moc specific MOC_CPPFLAGS can still be used
to pass flags to moc.

579b734346 qt: use our function table instead of directly calling gl functions 
Otherwise when building with --as-needed we would need to link to
a GL or GLES library.

b1bbdceeb2 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
