Integrate QAbstractVideoSurface API.

This introduces a QAbstractVideoSurface interface for implementing arbitrary
video outputs, and a QVideoFrame type.  Also included is the
QVideoSurfaceFormat class which is used to configure the input to a video
surface, and the QAbstractVideoBuffer class which allows QVideoFrames
to be constructed from non-native frame types.

+
+    The handle() of a buffer may also be used to manipulate it's contents using type specific APIs.

+    \brief The QAbstractVideoSurface class is a base class for video presentation surfaces.
+    \preliminary
+    \since 4.6
+
+    The QAbstractVideoSurface class defines the standard interface that video producers use to
+    inter-operate with video presentation surfaces.  It is not supposed to be instantiated directly.
+    Instead, you should subclass it to create new video surfaces.
+
+    A video surface presents a continuous stream of identically formatted frames, where the format
+    of each frame is compatible with a stream format supplied when starting a presentation.
+
+    A list of pixel formats a surface can present is given by the supportedPixelFormats() function,
+    and the isFormatSupported() function will test if a complete video format is supported.  In
+    some cases when a format is not supported; isFormatSupported() may suggest a similar format.
+    For example if a surface supports fixed set of resolutions it may suggest the smallest
+    supported resolution that contains the proposed resolution.
+
+    The start() function takes a supported format and enables a video surface.  Once started a
+    surface will begin displaying the frames it receives in the present() function.  Surfaces may
+    hold a reference to the buffer of a presented video frame until a new frame is presented or
+    streaming is stopped. The stop() function will disable a surface and a release any video
+    buffers it holds references to.

+    \class QVideoSurfaceFormat
+    \brief The QVideoSurfaceFormat class specifies the stream format of a video presentation
+    surface.
+    \preliminary
+    \since 4.6
+
+    A video surface presents a stream of video frames.  The surface's format describes the type of
+    the frames and determines how they should be presented.
+
+    The core properties of a video stream required to setup a video surface are the pixel format
+    given by pixelFormat(), and the frame dimensions given by frameSize().
+
+    If the surface is to present frames using a frame's handle a surface format will also include
+    a handle type which is given by the handleType() function.
+
+    The region of a frame that is actually displayed on a video surface is given by the viewport().
+    A stream may have a viewport less than the entire region of a frame to allow for videos smaller
+    than the nearest optimal size of a video frame.  For example the width of a frame may be
+    extended so that the start of each scan line is eight byte aligned.
+
+    Other common properties are the pixelAspectRatio(), scanLineDirection(), and frameRate().
+    Additionally a stream may have some additional type specific properties which are listed by the
+    dynamicPropertyNames() function and can be accessed using the property(), and setProperty()
+    functions.
