Here's the fourth version of the V4L2 subdev userspace API patches. Nothing
new under the sun, the patches have just been rebased on top of 2.6.37-rc3.

The two functions are mostly identical. They handle the copy_from_user
and copy_to_user operations related with V4L2 ioctls and call the real
ioctl handler.
Create a __video_usercopy function that implements the core of
video_usercopy and video_ioctl2, and call that function from both.
There's no reason to require subdevices to implement the core
operations. Remove the check for non-NULL core operations when
initializing the subdev.
