Functions
static void	usage (char *argv[])
	usage information for asynclook
static void	print_result (struct lookinfo *info)
	print result from lookup nicely
static void	lookup_is_done (void *mydata, int err, struct ub_result *result)
	this is a function of type ub_callback_t
static void	checkerr (const char *desc, int err)
	check error, if bad, exit with error message
static void	ext_check_result (const char *desc, int err, struct ub_result *result)
	check result structure for the 'correct' answer
static void	ext_callback (void *mydata, int err, struct ub_result *result)
	extended bg result callback, this function is ub_callback_t
static void *	ext_thread (void *arg)
	extended thread worker
static int	ext_test (struct ub_ctx *ctx, int argc, char **argv)
	perform extended threaded test
int	main (int argc, char **argv)
	main program for asynclook

Variables
static int	num_wait = 0
	global variable to see how many queries we have left
static int	q_is_localhost = 0
	if true, we are testing against 'localhost' and extra checking is done
int	optind
	getopt global, in case header files fail to declare it.
char *	optarg
	getopt global, in case header files fail to declare it.
