I don't think you need a UdpTransport.  I think you just need a
UdpTransportChannel.  Transports are silly things that we should delete and
replace with just TransportChannels (and then rename TransportChannels to
Transports).

When are we planning on doing that though? We talked about that coming later.

We'll remove the ICE and DTLS ones later.  But we don't need to add a *new* one
now.  There's no need for it.

  public:
-  P2PTransport(const std::string& name, PortAllocator* allocator);
-  virtual ~P2PTransport();
+  RawUdpTransport(const std::string& name, PortAllocator* allocator);
+  virtual ~RawUdpTransport();
 
  protected:
-  // Creates and destroys P2PTransportChannel.
   virtual TransportChannelImpl* CreateTransportChannel(int component);
   virtual void DestroyTransportChannel(TransportChannelImpl* channel);
 
-  friend class P2PTransportChannel;
+  friend class RawUdpTransportChannel;
 
-  RTC_DISALLOW_COPY_AND_ASSIGN(P2PTransport);
+  RTC_DISALLOW_COPY_AND_ASSIGN(RawUdpTransport);
