[media] gspca - kinect: New subdriver for Microsoft Kinect

The Kinect sensor is a device used by Microsoft for its Kinect project,
which is a system for controller-less Human-Computer interaction
targeted for Xbox 360.

In the Kinect device, RGBD data is captured from two distinct sensors: a
regular RGB sensor and a monochrome sensor which, with the aid of a IR
structured light, captures what is finally exposed as a depth map; so
what we have is basically a Structured-light 3D scanner.

The Kinect gspca subdriver just supports the video stream for now,
exposing the output from the RGB sensor or the unprocessed output from
the monochrome sensor; it does not deal with the processed depth stream
yet, but it allows using the sensor as a Webcam or as an IR camera (an
external source of IR light might be needed for this use).

The low level implementation is based on code from the OpenKinect
project (http://openkinect.org).
