Updated main code to SVN #20453.

Add entries in audio settings for configuring ALSA with HDMI output (Lodged as ticket #6502)

Build packages with VDPAU patch #20405-5

Should fix playback issues when audio and video are too far appart and you get a lot of messages like:

"Audio 686 ms behind video but already 75 video frames queued. AV-Sync might be broken. "
