Thank you Klaus for working on the positioner support. :)

I think I would be interested to have possibility for multiple positioners later, if VDR would only support it.
Currently I have only one dish, which is motorised. There I have a Quad LNB. VDR has three DVB-S2 tuners (+ unrelated DVB-T(2) tuners).
Tuner 1: Connected directly to LNB
Tuner 2: Connected directly to LNB
Tuner 3: Connected to LNB via motor
Tuner 3 is used for motor control only, no actual signal is being received there, even it would be and is possible, but this tuner is horrible with weak
transponders, yet it's the only tuner I have that can supply 18V to motor+LNB.
I have made VEEERY ugly patching to VDR (as I'm not really a software developer and don't know how things should be done, and I have done some unnecessary things
"just in case"), but I think sharing it will give some people some ideas. But atleast it is working perfectly in my environemnt. :) I don't know what kind of
unwanted things it may cause elsewhere.
So basicly what I did, I took fd_frontend of tuner 3 (identified by subsystemId), and use it as dfd_frontend. Then I made some changes to device bonding, to
restrict devices to same satellite source, instead of same band/polarisation. All devices are set in VDR configuration to "connected to cable 1".
And there I have it, somehow working motorised multi-tuner setup. :)
Patch assumes that VDR is patched with GOTOXX patch.
