[AMLUtils] Change some more permissions

In current Android 4.4.2 sources we need to change
permissions to 666 for following:

    /dev/amvideo
    /dev/amstream_sub
    /dev/amstream_sub_read
    /dev/amstream_rm
    /dev/amstream_mpps
    /dev/amstream_mpts
    /dev/amstream_abuf
    /dev/amstream_vbuf
ADD: [sets] allow to select art from child movies
[win32] remove unneeded local helper
Remove unused DVDMessageTracker class.
[omxplayer] Remove PCMRemap and handle multichannel mixing like ActiveAE

omxplayer uses pre-ActiveAE code for determining multichannel mixing.
Some of the decisions made with lfe and side/back channels are different.

I think it is better to match latest xbmc code exactly, and so use
ffmpeg to determine the mixing matrix in the same way as Pi Sink does.
