15 * Given a contact-id (minimum), load the PortableContacts friend list for that contact,
16 * and add the entries to the gcontact (Global Contact) table, or update existing entries
17 * if anything (name or photo) has changed.
18 * We use normalised urls for comparison which ignore http vs https and www.domain vs domain
20 * Once the global contact is stored add (if necessary) the contact linkage which associates
21 * the given uid, cid to the global contact entry. There can be many uid/cid combinations
22 * pointing to the same global contact id.
