raspi: use decoder implementation from pidvbip

Browse Source 
* remove ilclient
* use a decoder implementation similar to pidvbip instead,
  see https://github.com/linuxstb/pidvbip
* video is decoded in hardware (videocore)
* audio is decoded by libavcodec
* add a AVDec wrapper class for both audio and video decoders
* very raw, needs more polishing. But decodes audio and video :-)
* only tested with h264
