I'm leaning towards option 2 (doesn't matter a or b) right now. As 
Stefan says, the DataChannels objects are rather self-contained as they 
are specified right now. I mean, their states reflect the state of the 
underlying transport unless explicitly closed. So my take on this right 
now is that I think we shouldn't add onConnection and onClosedConnection 
if we go with option 2 unless we have specific use cases for them.
