 * xchan is your connection
 * We will load their friend list, and store in xlink_xchan your connection hash and xlink_link the hash for each connection
 * If xchan isn't provided we will load the list of people from url who have indicated they are willing to be friends with
 * new folks and add them to xlink with no xlink_xchan.
 *
 * Old behaviour: (documentation only):
 * Given a contact-id (minimum), load the PortableContacts friend list for that contact,
 * and add the entries to the gcontact (Global Contact) table, or update existing entries
 * if anything (name or photo) has changed.
 * We use normalised urls for comparison which ignore http vs https and www.domain vs domain
 *
 * Once the global contact is stored add (if necessary) the contact linkage which associates
 * the given uid, cid to the global contact entry. There can be many uid/cid combinations
 * pointing to the same global contact id. 
 *
