Zhiyi Zhang 354359197b gdi32: Add D3DKMTSetVidPnSourceOwner and D3DKMTCheckVidPnExclusiveOwnership stubs. 
D3DKMTSetVidPnSourceOwner needs to be implemented in the graphics drivers
because we need to maintain the VidPN source ownership information list
in the graphics drivers. For example, the graphics drivers need to release the
exclusive ownership when a new window is moved to a monitor which has been taken
exclusive ownership.

/* Notes on the implementation
*
* The implementation is based on dynamically resizable arrays of points and
* flags. I dithered for a bit before deciding on this implementation, and
* I had even done a bit of work on a linked list version before switching
* to arrays. It's a bit of a tradeoff. When you use linked lists, the
* implementation of FlattenPath is easier, because you can rip the
* PT_BEZIERTO entries out of the middle of the list and link the
* corresponding PT_LINETO entries in. However, when you use arrays,
* PathToRegion becomes easier, since you can essentially just pass your array
* of points to CreatePolyPolygonRgn. Also, if I'd used linked lists, I would
* have had the extra effort of creating a chunk-based allocation scheme
* in order to use memory effectively. That's why I finally decided to use
* arrays. Note by the way that the array based implementation has the same
* linear time complexity that linked lists would have since the arrays grow
* exponentially.
*
* The points are stored in the path in device coordinates. This is
* consistent with the way Windows does things (for instance, see the Win32
* SDK documentation for GetPath).
*
* The word "stroke" appears in several places (e.g. in the flag
* GdiPath.newStroke). A stroke consists of a PT_MOVETO followed by one or
* more PT_LINETOs or PT_BEZIERTOs, up to, but not including, the next
* PT_MOVETO. Note that this is not the same as the definition of a figure;
* a figure can contain several strokes.
*
