Please make the following changes to tcp_server_socket_win.h
as well.

The AllowAddressReuse() method should be added to the
ServerSocket interface.

Remove "Sets corresponding flags to" from this comment.
This comment should start with "Allows the socket to share ..."

Change "Bind()" to "Listen()".

Done. Also moved the comment to interface.
