The 'mirrored' property indicates the QVideoFrames need to be mirrored
along their vertical axis. This is typically needed for video frames
coming from a front camera on a mobile device.
This is implemented as a string-based property. In Qt 5.6, this should
be replaced by a new public function.

Using qFuzzyCompare in operator== makes it impossible to create a
consistent qHash() overload for the class later on (qFuzzyCompare
is not transitive).
It is unlikely that there will be numerical instability for frame
rates. If there is, qFuzzyCompare should be overloaded for either
this class or the FrameRateRange class.

When stopping, we don't actually stop the GStreamer pipeline, we just
pause it and prevent preroll frames from being shown.
We also need to make sure the last presented frame is cleared in that
case, otherwise it stays on screen.

It was the backend's responsibility to handle resource files in an
appropriate way. In practice, it was either not handled at all,
or implemented in an almost identical manner in every backend
that does handle it.
This is now dealt with in QMediaPlayer, always passing to the
backend something it will be able to play. If the backend has the
StreamPlayback capability, we pass a QFile from which it streams
the data. If it doesn't, we copy the resource to a temporary
file and pass its path to the backend.

There are cases where blocking operations happening in the video sink
need to be unblocked, that's why GstBaseSink has an unlock() virtual
function. Since our custom video sink blocks when starting and when
rendering a frame (while waiting for the main thread to actually do
these operations), we need to implement the unlock() function in order
to unblock these operations when requested by GstBaseSink.

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.

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.
