[VDPAU] Support H264 Hi10 via vdpau

this would be a an even more minimal approach to get those two fields
shipped. But as we have to decide if the target decoder can actually
do hi10p an new profile with a new extended struct would perhaps be
the better idea. So the actual vdpau decoder can tell itself if it
supports hi10p or not.

I don't know what happens when e.g. nvidia vdpau gets hi10p data in
the edited picture struct without a chance to distinguish it.

like
@@ -2821,6 +2821,12 @@ typedef struct {

     /** See \ref VdpPictureInfoH264 for instructions regarding this field. */
     VdpReferenceFrameH264 referenceFrames[16];
+
+    /* The following two fields are used for Hi10p */
+    /** Copy of the H.264 bitstream field. */
+    uint8_t  bit_depth_luma_minus8;
+    /** Copy of the H.264 bitstream field. */
+    uint8_t  bit_depth_chroma_minus8;
 } VdpPictureInfoH264;

In that case the vdpauinfo patch would also not be needed.

Best Regards
Peter
