Previously we had an issue that every other update_active_status
request for a particular realm would result in doing the expensive
query to compute the list of active users in that realm. It turned
out this was because on every update_active_status request, we'd queue
an event that would have the effect of clearing the cache, even if
nobody's tatus changed. This fixes that issue, by only clearing the
cache for a realm if someone's status actually changed (or the 60s
timeout expires).

wget users report certificate errors on the API download, apparently
due to wget's lack of support for TLS SNI until recently. Adding www
to the download link should work around this problem. (Trac #1400)

This improves the performance of the get_old_messages queries when
loading the home page by about a factor of 2.5x.

This is in preparation for having a case in which we query the
database directly to get the message flags, without going through a
UserMessage object.

This decreases the average size of the message dicts in memcached by
about half, without any significant change in the overall performance
of the query. Since these message dicts are a significant fraction of
what we put in memcached, this seems like a worthwhile optimization.

memcached stores objects sent to it using pickling, which is very
slow. We work around this by sending memcached strings (i.e. JSON
dumps); pickling doesn't slow things down too much if all it is
getting is a string.
(imported from commit 0f0e534182eccb76c5731198e05a9324a1cef316)
This saves something like 15ms on our 1000 message get_old_messages
queries, and will save even more when we start sending JSON dumps into
our memcached system.
We need to install python-ujson on servers and dev instances before
pushing this to prod.

Upon discussing with acrefoot, my new conclusion is that
the page should only look this way if you're going through
the workflow outlined in Trac #1391 -- otherwise it should
remain the way it is.

The old bucket was versioned and didn't allow deletes. This was
great for paranoia, but not so great for being able to delete old
backups.

I hadn't changed it previously out of paranoia in the case we had a
faulty failover and had two masters both uploading to the same place.
However, I now don't think this can happen, as recovery completion
will cause Postgres to start a new timeline.

update_onboarding_steps requests to the server every time they sent a

We had a few bugs where we were using a raw Django database query to
get a UserProfile object. This might seem OK, but going through
memcached is more efficient, and also guarantees that we get back the
.select_related() version of the object, so that if we later access
related fields like user_profile.realm.domain, we don't end up doing a
second database query as well.
Fixing these should in practice save a substantial number of database
queries on handling update_status_list requests, which happen very
often and access user_profile.realm.domain.

Instead of calling test(result), we emulate the behavior of
calling SimpleTestCase.__call__, minus the results protocol.
