Removed function since we are passing in constructor

+
  protected:
   BlimpConnection();
 
   // ConnectionErrorObserver implementation.
   void OnConnectionError(int error) override;
 
  private:
   std::unique_ptr<PacketReader> reader_;
   std::unique_ptr<BlimpMessagePump> message_pump_;
   std::unique_ptr<PacketWriter> writer_;
   std::unique_ptr<BlimpMessageProcessor> outgoing_msg_processor_;

Make this a BlimpMessageSender, and move BlimpMessageSender out of an anonymous
namespace. That way, we preserve type information and don't have to resort to a
static_cast<> later on.

   base::ObserverList<ConnectionErrorObserver> error_observers_;
 
   DISALLOW_COPY_AND_ASSIGN(BlimpConnection);
 };
 
 }  // namespace blimp
 
 #endif  // BLIMP_NET_BLIMP_CONNECTION_H_
