First steps towards a proper video playback engine - replace vcodec_omx.c code with a version that does not use ilclient (the audio code still uses ilclient, but that will be removed next), to better see what is going on.  Remove the hacked A/V sync in preparation for doing it properly - this means audio is now out of sync with the video.  Also display the status of the OMX (video) buffers and the video/audio queues.
