Fix #3085

TODO:
 - only inhibit screen saver when input is *not* paused.

Pointed by jb.

We could probably have deinterlace=Auto, as it seems to work reliably enough on freebox channels.

HAL is officially deprecated. The new udev discs module provide the same
functionality in VLC. Moreover, the plugin was waking up the CPU at
regular intervals. Last, InitDeviceValues seemed to cause problems with
wrong disc paths being saved to vlcrc for some people
