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.
