flip_server: rename create_listener.* for clarity
This patch renames create_listener.* to tcp_socket_util.* as it is
really a collection of tcp helper functions. While at it also rename the
functions CreateListeningSocket and CreateConnectedSocket, to
CreateTCPServerSocket and CreateTCPClientSocket respectively. As the pair
Server/Client is much more common and easier to read/understand in the
call sites than Connected for example and add TCP to make it clear that
they create tcp sockets rather than udp or unix domain sockets for
example.
