e3c16d0194 qmlglsink: Keep old buffers around a bit longer if they were bound by QML
We don't know exactly when QML will stop using them but it should be
safe to unref them after at least 2 more buffers were bound.

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.

Fixes #798

625e56d3b4 qmlgloverlay: fix multiple elements with Qt 5.15
With Qt 5.15 multiple qmlgloverlay elements would produce:

ASSERT: "!m_gl->property(QSG_RENDERCONTEXT_PROPERTY).isValid()" in file /path/to/qt5/qtdeclarative/src/quick/scenegraph/qsgdefaultrendercontext.cpp, line 121

Workaround by setting the (seeminigly unused) property before
initialization.

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.

3e0d557744 qmlgl: ensure Qt defines GLsync to fix compile on some platforms
By explictly including QtGui/qopengl.h we force the code path that
defines GLsync in the Qt-specific way. Without that, some platforms
failed to compile the qmlgl plugin, since neither Qt nor gstreamer
defined GLsync then, leading to e.g.:
