fbf60a61a0 qtitem: don't potentially leak a large number of buffers
The only other place where these queued buffers are removed, is in
setCaps() but that is not called at all on shutdown so this list of
buffers could not be removed.

c75bd32539 qml: don't use buffers that have invalid contents
If the GL context is not shareable, ignore it.

A future change may also not output the relevant output either.

c7181bedac qt: return a different GstGLDisplay object when the first sink requests

36b794f9ff qmloverlay: Use first found GstGLVideoItem as widget property
GstGLVideoItem is required to render input video in the overlay's qml.
And currently qmlgloverlay requires to set this GstGLVideoItem to its widget property.

Instead of fetching GstGLVideoItem from the overlay's root object (root-item prop),
and setting it back as a widget (widget prop),
proposing to use found GstGLVideoItem in the current object hierarchy (passed in qml-scene) by default.

Also useful in Python, which solves the issue when casting gpointer <=> QQuickItem* is required.

27ecd2c30d qmlglsink: fix crash when created/destroyed in quick succession
The crash is caused by a race condition where the render thread
calls a method on the QtGLVideoItem instance that was
previously destroyed by the main thread.
Also, less frequently, QtGLVideoItem::onSceneGraphInitialized
is called when QQuickItem::window is null, also causing a crash.

099712338f qt: Rework how we find the Qt QPA header
Instead of querying the Qt include path from the dependency or from
qmake, rely on the qt5qml_dep to set the include path to QtGui
correctly, and look for the header inside the private includedir.

Then we can use that path to include the header directly.
