9  * Given a contact-id (minimum), load the PortableContacts friend list for that contact,
10  * and add the entries to the gcontact (Global Contact) table, or update existing entries
11  * if anything (name or photo) has changed.
12  * We use normalised urls for comparison which ignore http vs https and www.domain vs domain
13  *
14  * Once the global contact is stored add (if necessary) the contact linkage which associates
15  * the given uid, cid to the global contact entry. There can be many uid/cid combinations
16  * pointing to the same global contact id.
