If an application can tag its audio streams with something like
"video", "music", "phone", "event" or suchlike, i like to call this a
"role". gst likes to call this a "class".

libcanberra/PA know these roles:

 event       -- event sounds
 production  -- audio production programs (wav editors ...)
 filter      -- a stream that is just an output of some kind of other filter element
 abstract    -- an abstract sound like sine test sounds and similar
 stream      -- a generic stream, streamed in from another host or sound server

Right now gst-pulse doesn't allow the app to set the role when a
pipeline is connected. I need to fix that.
