Support can be enabled at configure time by using "--with-adns=DIR". If support is enabled, async queries happen whenever host name resolution is enabled. Do we need a separate preference for async queries? Currently, only IPv4 reverse queries are supported. I can add IPv4 forward lookup support, but I don't have any way to test IPv6 queries. svn path=/trunk/; revision=7640
