FBO rendering and grabbing a QImage.

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.

There already was a control interface for the viewfinder settings
but no real public C++ API and a partial QML API.
This patch adds a new C++ API and improves the QML API.
Supported viewfinder settings are resolution, minimumFrameRate,
maximumFrameRate and pixelFormat. The camera can be queried for
the supported values for each of these settings.
A new control interface was created to match the new API.

This is essential for embedded applications that are not happy with

This makes constructs like the following functional on devices like
i.MX6 with MIPI cameras:

Camera input is often in this format. Until now the lack of GL_VIV_I420 (which
was presumably missing in older versions of the extension?) in the format list
resulted in falling back to the built-in i420 node instead of the zero-copy imx6
one. This is now corrected by adding the correct format mapping.

not picked up since only the egl one is seen by the system. With the fix both plugins
