As this is a major rewrite, I decided to fix a few 8-space indent at the first
lines of the driver, and remove a few trailing spaces. The only real changes up 
to the line 114 are some include file changes at hunks 1 and 2 and the increment
of the driver version. The real fun starts on this hunk:

@@ -114,6 +122,12 @@ v4lSetup(pointer module, pointer opts, int *errmaj, int *errmin)
 #define VIDEO_YUV     2  /* yuv overlay (to offscreen memory + hw scaling) */
 #define VIDEO_RECLIP  3  /* temporarly off, window clipping changes */
 
+typedef struct _XvV4LCtrlRec {
+    struct v4l2_queryctrl	qctrl;
+    Atom			xv;
+    INT32			min, max;
+} XvV4LCtrlRec, *XvV4LCtrlPtr;

...

Basically, almost all the driver were touched by this patch, as most of the code
there is due to the V4L API.

Cheers,
Mauro
