	* socket-io.c (convert_sockopt_level_and_name): If the system
	doesn't define SOL_IP or SOL_TCP, get them by hand using
	getprotobyname() and caching the values (because this could be a
	slow operation).
	(ves_icall_System_Net_Sockets_Socket_SetSocketOption_internal):
	Don't attempt to add or drop memberships unless the system
	supports it.
