 * \brief
 * Defines dns_badcache_t, the "bad cache" object.
 *
 * Notes:
 *\li 	A bad cache object is a hash table of name/type tuples,
 *	indicating whether a given tuple known to be "bad" in some
 *	sense (e.g., queries for that name and type have been
 *	returning SERVFAIL). This is used for both the "bad server
 *	cache" in the resolver and for the "servfail cache" in
 *	the view.
