[PATCH] bttv driver update.

This updates the bttv driver.  Changes:

 * adaptions to the video-buf changes send in a previous mail.
 * adaptions to recent i2c changes in the kernel.
 * first code bits the pixelview digital camera support (not
   working yet).
 * lots of small fixes/changes for specific TV cards.
