adig previously performed manual parsing of the DNS records. Now it can focus strictly on formatting of output data for printing. It simply iterates across the parsed DNS packet and queries for the RRs, parameters for each RR, and the datatypes for each parameter. adig will now automatically pick up new RRs from the c-ares library due to the dynamic nature.
The adig format also now more closely resembles that of BIND's `dig` output.
A few more helpers needed to be added to the c-ares library that were missing. There ware a couple of minor bugs and enhancements also needed.
Example:
```
./adig -t ANY www.google.com
; <<>> c-ares DiG 1.21.0 <<>> www.google.com
