Comment 68 for bug 963895

If you look at the size of the required changes (see e.g. Comment 25), I do not see any reliable way to produce a version unless we replace 4.8 branch with the trunk version. And there are more changes ahead, because I only fixed the "Control/MixDevice" usage - and the same has to be done for the "Cards/Mixer/MixerBackend" level, which will make the changes even bigger.
This would require that I can disable new/unstable features from trunk with feature switches.
