Also add some more decoders in ffmpeg configuration (wav).
Also stop audio device restart on PKEY_AudioEndpoint changes.
Also deduce channel layout from channel count in ffmpeg loaders.
Something has changed in Qt libraries remote layout so now the perl
init-repository script from the old Qt version doesn't work anymore.
We init the submodules using script from the latest Qt version and
after that we checkout the desired version by tag in all submodules.
