From: Geliang Tang tanggeliang@kylinos.cn
Include network_helpers.h in prog_tests/sockopt_inherit.c, use public helpers make_sockaddr() and start_server_setsockopt() instead of the local defined function start_server(). This can avoid duplicate code.
Add a helper setsockopt_loop() to set SOL_CUSTOM sockopt looply, and pass it to start_server_setsockopt().
