[vdr] Patch #1: Kill process before opening Devices

Hi list,

I'll be releasing this and a few other patches for VDR 1.3.33, which have evolved during the last months while working on XeatreOS (a distribution based on LinVDR 0.7, which is used for the Xeatre boxes, http://www.xeatre.tv/). Some of their functionality may already be included in plugins or other patches. Nevertheless, I'd like to release them now, and let everybody decide whether they are useful or not.

This first one adds a commandline parameter '-k' to VDR. Using this, you can specify an arbitrary PID which will be killed just before VDR opens the DVB devices. This way the gap between a possible boot-up screen/movie and Live-TV gets shorter.

Greetings, Sascha Volkenandt
