bba07f3c35 qt: The code requires at least C++11 
... and clang requires this to be specified on the commandline while gcc
nowadays defaults to C++11 or even newer.

f15a3e3657 qmlglsink: check qt_context_ first in GstQSGTexture::bind() 
When start qmlglsink app, it will set NULL buffer to GstQSGTexture

gst_gl_context_activate() fail.

Sometimes wglCreateContextAttribsARB() exists, but
isn't functional (some Intel drivers), so it's

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

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.

2b7495bbc1 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.

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
