Here comes the "dvb-c analog module hack"

- if the analog module is detected, the saa7113 is initialized and
  some more v4l2 ioctls are available. you can use "xawtv" now to
  switch between "dvb" and "analog" input. when you are one the
  "analog" input, you can tune in analog channels with the cursor
  keys via v4l2.
  currently, this is a big hack -- tuning is not mutually exclusive,
  so "szap" and v4l2 tuning can interfere with each other. the
  demodulator address is hardcoded to 0x09.

Other changes:
- changed the saa7146 ioctl parameters, give out the data of the
  current device open "fh" (=> "file handle"), not the pointer to the
  device structure "dev". It is "dev = fh->dev".

Some stuff does not work:
- analog audio does not work. does the msp3400 need to be reprogrammed?
- one field is "missing", so the picture is very bad and
  capturing does not work neither. this needs to be investigated by
  looking at the programming the windows driver uses for the saa7146
