gspca - kinect: fix comments referring to color camera

Use the expression "video stream" instead of "color camera" which is
more correct as the driver supports the RGB and IR image on the same
endpoint.

gspca - kinect: move communications buffers out of stack

Move large communications buffers out of stack and into device
structure. This prevents the frame size from being >1kB and fixes a
compiler warning when CONFIG_FRAME_WARN=1024:

drivers/media/video/gspca/kinect.c: In function ‘send_cmd.clone.0’:
drivers/media/video/gspca/kinect.c:202: warning: the frame size of 1548 bytes is larger than 1024 bytes

Add a configurable stream_flag field

For now only video stream is supported which has stream_flag = 0x80, but
having the value hardcoded in the sd_pkt_scan routine didn't look
pretty.
This way there is more flexibility in preparation for adding depth
stream support.

Update copyright and remove marcan name

libfreenect is not only by Héctor Martín anymore and I managed to
misspell his name anyways, so just mention the project and he'll get
implicit credit.

Add IR stream support.

The IR stream comes in a 10 bpp packed array, so a Y10B format is used
for that.

Use the name video_camera instead of color_camera.

This is in preparation for IR mode support.
