Factor out parsing of reference-header values and pickup In-reply-to.

Browse source 
This is in preparation for doing a couple of passes over the references,
(one to add terms to the database, and a second to find the thread_id).

We also now parse the In-reply-to header which we were missing before.
We treat it identically to the References header.
