a_Dns_dillohost_to_string()

void a_Dns_dillohost_to_string	(	DilloHost *	host,
		char *	dst,
		size_t	size

Dns memory-deallocation.

(Call this one at exit time) The Dns_queue is deallocated at execution time (no need to do that here) 'dns_cache' is the only one that grows dynamically

Side effect: a thread is spawned when hostname is not cached.
