/** function update (): polls for updates on one or more Contributor feeds
@desc
# Arguments:
- $uri (string): Either the URI of the feed to poll, the URI of the
(human-readable) website whose feed you want to poll, or null.
If $uri is null, then FeedWordPress will poll any feeds that are
ready for polling. It will not poll feeds that are marked as
"Invisible" Links (signifying that the subscription has been
de-activated), or feeds that are not yet stale according to their
TTL setting (which is either set in the feed, or else set
randomly within a window of 30 minutes - 2 hours).
# Returns:
- Normally returns an associative array, with 'new' => the number
of new posts added during the update, and 'updated' => the number
of old posts that were updated during the update. If both numbers
are zero, there was no change since the last poll on that URI.
- Returns null if URI it was passed was not a URI that this
installation of FeedWordPress syndicates.
# Effects:
- One or more feeds are polled for updates
- If the feed Link does not have a hardcoded name set, its Link
Name is synchronized with the feed's title element
- If the feed Link does not have a hardcoded URI set, its Link URI
is synchronized with the feed's human-readable link element
- If the feed Link does not have a hardcoded description set, its
Link Description is synchronized with the feed's description,
tagline, or subtitle element.
- The time of polling is recorded in the feed's settings, and the
TTL (time until the feed is next available for polling) is set
either from the feed (if it is supplied in the ttl or syndication
module elements) or else from a randomly-generated time window
(between 30 minutes and 2 hours).
- New posts from the polled feed are added to the WordPress store.
- Updates to existing posts since the last poll are mirrored in the
WordPress store.
@param string|null $uri Either the URI of the feed to poll, the URI of the (human-readable) website whose feed you want to poll, or null.
@param mixed|null $crash_ts Unknown purpose.
