Exposure, Flash, Focus and Locks controls were always initialized,
even when the GstPhotography interface was not available (on desktop
for example), causing some warnings and fooling the user in believing
that these features were available.
These controls are now lazily initialized and only when
GstPhotography is available.
The zoom control is not compile-checked anymore since it doesn't
actually require GstPhotography.

Not all status changes where reported and setting the QCamera

State and status changes have been refactored.
Camera status is now reported directly by the camera session.
Setting the camera state to LoadedState now sets the camerabin to
GST_STATE_READY, that allows to query for camera capabilities without
having to start the camera (and have a valid viewfinder).

The viewfinder resolution must be in the same aspect ratio as the
image capture resolution. When adjusting the viewfinder resolution to
comply with that restriction, we assumed that the ratios had to be
exactly equal. Though, in practice, there can be a small difference.
For example for resolutions 2592x1952 (ratio=1.3278) and resolution
640x480 (ratio=1.3333).

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.

one. This is now corrected by adding the correct format mapping.
