[PATCH] add v4l1-compat module.

This adds the v4l1-compat module.  This is a module which can translate
most (old) v4l1 ioctls into the new v4l2 API.  This makes it easier for
v4l2 drivers to present both old v4l and new v4l2 APIs to video4linux
applications.  The saa7134 driver uses this for example.
