dnsdbq - 2.6.4-1 main

This is a pure C99 program that accesses passive DNS database systems such as:
.
* the DNSDB API server at Farsight Security
* the CIRCL pDNS server at Computer Incident Response Center (LU)
.
An API key is required for operation. The command syntax was inspired by a
Python script called dnsdb_query, but significant departure has occurred,
largely inspired by a modern understanding of "time fencing" and a desire for
new features such as CSV output and JSON reprocessing.
