These are some queries on API usage, desktop usage, and
Android usage that would be of interest to Waseem. These
will eventually be subsumed into /activity, but some interim
data issues may make them easier to keep separate for now.

In order to support iOS Push Notifications, we need to keep track
of a device's unique APNS Token. These are delivered to our iOS

This requires renaming the account in Google Apps at the time we
deploy this; we'll probably want to do this during off hours to avoid
any user-visible downtime.
This also updates some related email addresses.

This may require just doing an mv on the home directory, plus changing
the home directory in /etc/passwd. It should of course be done carefully.

We want the UserActivity.query field to reflect the name of the
function for REST calls, not the URL, and we accomplish this by
setting request._query to target_function.__name__.

Add the number of person-minutes for the last 24 hours to the
realm report on the main tab of /activity.
(imported from commit 2ff46eacc4c8276ab0407fc6ff9f28f5137f1ed2)
This tab shows how long each user has been on during the last 24
hours, using data from UserActivityInterval. Much of the code
is borrowed from analyze_user_activity.py, but in this version
we set the time interval to be the last 24 hours and sort by
realm and email. I also ensure that it only executes one
query to get all the data (and there's test coverage for that).

Waseem is ok with removing the client-specific tabs on the
main /activity page. This reduces the number of queries from
25 to 1. We might eventually restore some of that logic, but
we will do it more efficiently. A lot of the data for
non-website clients is kind of unreliable, anyway.
The page looks kind of funny with only one tab, but that
will be fixed in the next commit.

When we don't already have old messages in cache, we need to
fetch data from the database and create dictionaries for the
cache. This commit makes that process work in 50ms, instead
of 130ms, for the data set in test_bulk_message_fetching(),
which is 602 records. Before this commit we had about 132
microseconds of unnecessary churn per message, because we
were fetching DB fields we didn't need and incurring the cost
of the Django ORM. Now we use values() to get only the columns
we need, and we take advantage of previous commits that make
our code less OO and more function-driven, so we can pass the
values directly to build_message_dict() without having to create
objects.
A couple caveats on this commit:
1) I haven't been able to get good measurements on the overall
effect on get_old_messages_backend(). If you kill the cache to
force DB queries, you introduce noise related to sessions and
user profiles.
2) Look at the long comment in this commit related to
re-rendering messages in this codepath. The problem precedes
this commit.

The realm should always be the realm of the stream, and we should
always pass in a stream rather than sometimes passing in a stream name
and other times passing in a stream.

We have a handy bulk_add_subscriptions function to make cases

On my machine this reduces the number of db queries during account_register

It shows domains and how many active users they have. A
user is consider active if they have done something at least
as active as updating their pointer in the last day. Domains
with no meaningful activity in the last two weeks are excluded
from the report.

A small functional change here was to eliminate an enormous "Usage"
headline that was already implicit from the tabs. It would have
complicated the refactoring to try to preserve it, and I don't think
anyone will miss it.
Extracting this template will give us a little more flexibility
to customize future tabs in the /activity page.

We are still showing the same data points, but the logic to drill
down on details for a particular realm is now all server side,
not client side, and we are smarter about omitting fields. In
summary mode, we don't show empty Name or Email columns. In
detailed mode, we show the realm as a headline instead of a column.
In this version you do lose the ability to see all system users in
the same view, but Waseem is ok with this.

When you load the activity report, it will just show summary
counts for realms, but if you click on a realm, you will see
details about users in the realms. You can also click "Show all"
to see an interleaved view of realms and users.

get_subscribers_backend() now calls the new get_subscriber_emails()
function, which just queries the email field:
"zerver_userprofile"."email"
...instead of querying about 40 fields that it never uses.
I was able to verify the query slimming by watching my postgres server log.
Also, you can verify that the ORM does roughly 16x less work using values():
>>> def f(): return [sub.user_profile.email for sub in list(Subscription.objects.all().select_related())]
...
>>> def g(): return [row['user_profile__email'] for row in list(Subscription.objects.all().values('user_profile__email'))]
...
>>> def timeit(func): t = time.time(); func(); return time.time() - t
...
>>> timeit(f)
0.045198917388916016
>>> timeit(g)
0.002752065658569336
