modern asynchronous DNS API (development)

 getdns is a modern asynchronous DNS API. It implements DNS entry
 points from a design developed and vetted by application developers,
 in an API specification edited by Paul Hoffman. This API intends to
 offer application developers a modernized and flexible way to access
 DNS security (DNSSEC) and other powerful new DNS features; a
 particular hope is to inspire application developers towards
 innovative security solutions in their applications.

 This is the full development version of the library.
