[PATCH] bttv driver update 

This patch updates the bttv driver.  Changes:

 * moved much code to the generic video-buf.c helper module
   (bttv-driver.c, bttv-vbi.c, videobuf.c).
 * a number of changes in the card list and the card-specific code
   (bttv-cards.c).
 * misc small fixes here and there.
