Ian Armstrong 88ab075aee 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.
