V4L/DVB (7243): ivtv: yuv framebuffer tracking
The existing yuv code limits output to the display area occupied by the framebuffer. This patch allows the yuv output to be 'detached' via V4L2_FBUF_FLAG_OVERLAY. By default, the yuv output window will be restricted to the framebuffer dimensions and the output position is relative to the top left corner of the framebuffer. This matches the behaviour of previous versions. If V4L2_FBUF_FLAG_OVERLAY is cleared, the yuv output will no longer be linked to the framebuffer. The maximum dimensions are either 720x576 or 720x480 depending on the current broadcast standard, with the output position relative to the top left corner of the display. The framebuffer itself can be resized, moved and panned without affecting the yuv output.
