sink,source: Allow sample rate switching with corked streams

Browse source 
This updates corked streams' resamplers when switching sample rates on a
sink/source, which means the restriction of allowing sample rate updates
only when no streams are attached to a sink/source is now relaxed to
preventing updates only when there is a running stream attached.
