v1.0.0-rc2

• Breaking Renamed Agent to Transport.
• Breaking Renamed hostport.Peer's AddSubscriber/RemoveSubscriber
  to Subscribe/Unsubscribe.
• Breaking Updated Peer.StartRequest to take a dontNotify peer.Subscriber to exempt
  from updates. Also added Peer.EndRequest function to replace the finish callback
  from Peer.StartRequest.
• Breaking Renamed peer.List to peer.Chooser, peer.ChangeListener to peer.List
  and peer.Chooser.ChoosePeer to peer.Chooser.Choose.
• Reduced complexity of single peer.Chooser to retain the passed in peer immediately.
• Breaking Moved /peer/list/single.go to /peer/single/list.go.
• Breaking Moved /peer/x/list/roundrobin.go to /peer/x/roundrobin/list.go.
• HTTP Oneway requests will now process http status codes and returns appropriate errors.
• Breaking Update roundrobin.New function to stop accepting an initial peer list.
  Use list.Update to initialize the peers in the list instead.
• Breaking: Rename Channel to ClientConfig for both the dispatcher
  method and the interface. mydispatcher.Channel("myservice") becomes
  mydispatcher.ClientConfig("myservice"). The ClientConfig object can
  then used to build a new Client as before:
  NewMyThriftClient(mydispatcher.ClientConfig("myservice")).
• A comment is added atop YAML files generated by the recorder to help
  understanding where they come from.
