From b69ff1c846250939de3e4f32ff4d07d6ee415009 Mon Sep 17 00:00:00 2001

Subject: Add validatechain.c and move some code to common.c.

dns-net2wire.c is nothing but an ugly hack on top of getdns_query.c
making it save answer, validation_chain and trust anchors to three
separate files. Used for testing purposes.

validatechain takes the above mentioned three files as input and
performs DNSSEC validation.
