IMPORTANT: It would be better to list this method immediately after the similar
AdoptConnectedSocket method. The comment should explain the difference between
the two methods, and what each of the methods is intended for.

Since no code in src/net (not even a unit test) uses the new method, the comment
is crucial. It would be good to add a unit test.

Renamed to AdoptListenSocket since the adopted |socket| can only be used for
accepting connections. And moved to just below AdoptConnectedSocket.

Also added a AcceptForAdoptedListenSocket test.

 
   int Listen(int backlog);
   int Accept(scoped_ptr<TCPSocketWin>* socket,
              IPEndPoint* address,
              const CompletionCallback& callback);
 
   int Connect(const IPEndPoint& address, const CompletionCallback& callback);
   bool IsConnected() const;
   bool IsConnectedAndIdle() const;
