The factory follows the same principles as PeerConnectionFactory; various modules can be passed into its constructor but default implementations are provided. Currently the only object the factory can create is a UdpTransport (need to start somewhere). UdpTransportChannel (renamed to UdpTransport) will now accept a socket passed into its constructor, relying on the factory to create the socket. This allows some simplifications to be made, such as getting rid of "State" since the only states are now "has destination set or doesn't".
