That last sentence can be objected to - the function takes the sink as
an argument, so it can be said to operate on the sink. But then the
verb should be something that the sink does, like "take" ("move" is
something that streams do). So pa_sink_take_streams()? Or
pa_sink_take_streams_that_prefer_it()? I don't know. My weak preference
at this point is pa_core_move_streams_to_newly_available_sink(). It's
quite descriptive, but unfortunately lacks the distinction that only
those streams that prefer the newly available sink are moved.
