* @brief Fetch the contact id for a given url and user * @brief Fetch the contact id for a given url and user

* First lookup in the contact table to find a record matching either `url`, `nurl`,
* `addr` or `alias`.
*
* If there's no record and we aren't looking for a public contact, we quit.
* If there's one, we check that it isn't time to update the picture else we
* directly return the found contact id.
*
* Second, we probe the provided $url wether it's http://server.tld/profile or
* nick@server.tld. We quit if we can't get any info back.
*
* Third, we create the contact record if it doesn't exist
*
* Fourth, we update the existing record with the new data (avatar, alias, nick)
* if there's any updates
*
* @param string $url Contact URL * @param string $url Contact URL
* @param integer $uid The user id for the contact * @param integer $uid The user id for the contact (0 = public contact)
