V4L/DVB (3430): Add new internal VIDIOC_INT commands 



- Add new internal VIDIOC_INT commands for setting the tuner mode,
for putting a chip into standby mode and to set/get the routing
of inputs/outputs of audio or video of a chip. These new commands
will replace older commands that are no longer up to the task.
