* 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.
