Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Add the QAbstractVideoFilter base class and integrate it with VideoOutput.
This can be used to perform arbitrary filtering or image processing
on the frames of a video stream of a VideoOutput element right before
the OpenGL texture is provided to the scenegraph by the video node.
This opens up the possibility to integrate computer vision
frameworks or accelerated image processing with Qt Quick applications
that display video streams using Qt Multimedia.
Conceptually it is somewhat similar to QVideoProbe, this
approach however allows modifying the frame, in real time
with tight integration to the scenegraph node, and targets
Qt Quick meaning setting up the filter and processing the results
of the computations happen completely in QML.
[ChangeLog] Added QAbstractVideoFilter that serves as a base class for QML
video filtering elements that integrate compute, vision, and image processing
frameworks with VideoOutput.

Enable qt.multimedia.video to get the logs. Also enhance the printing
when creating the video node implementation. It is essential to have
an easy way to figure out what handle and formats the node in use
supports.

Don't assume the camera frames are always in the same orientation as the
display in its primary orientation. We now take into account the camera
sensor position and orientation to calculate the viewport orientation.

When trying to play video in an overlay window, the video fails to
be displayed because everything that would cause updateGeometry to be
called on the backend has already occurred prior to the backend having
been created.
