[vdr] Add support for [non-standard?] DiSEqC switch "MAXIMUM DiSEqC 4/1"

Hi,

The local guy over here mounted what he claimed is a fully standard 4/1
DiSEqC switch which works with every sat-receiver around. After some
brief investigation, it appears this DiSEqC switch is using a non-standard?
scheme, which is not supported by w_scan nor vdr. Correct me if I'm wrong.

To get the switch working with VDR I need an option to turn off the switch
power. This is part of the sequence to program the switch.

I've attached patches for w_scan and VDR to work with the DiSEqC
switch I've got. I don't have any documentation on the switch. All the
programming was the result of two days of reverse engineering. And I did
not open the switch either :-)

Good luck!

I hope the patches can be included into VDR and w_scan. Not sure if this is the right list to post the patches.
