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.

Only call a function on the message object in the unfortunate
situation that we are rendering new content in to_dict_uncached().
Long term, it would be nice if this function didn't have side
effects, and we had a better strategy for upgrading rendered
content when bugdown versions change.

This function doesn't require the whole UserProfile object to
create the avatar url, and we call it from Message.to_dict_uncached().

For a bunch of self-dot references, move them to the top. (This
is kind of funny out of context, but it sets us up for future
refactorings.)

If this line of code were ever called, it would crash anyway,
because it would be an unknown type, and Recipient.type_name()
would raise a KeyError.

This is a variation of get_display_recipient that takes
values instead of an object, so that it is decoupled from
the Django object system.

If it's ok for the tests to use memcached, it should be ok
for them to use the in-process cache too.

This is a harmless extraction designed to allow subclasses override
the behavior of how rendered content gets saved.

The get_status_dict_by_realm helper gets called whenever our
realm user_presences cache expires, and it used to query these fields:
"zerver_userpresence"."id", "zerver_userpresence"."user_profile_id", "zerver_userpresence"."client_id", "zerver_userpresence"."timestamp", "zerver_userpresence"."status", "zerver_userprofile"."id", "zerver_userprofile"."password", "zerver_userprofile"."last_login", "zerver_userprofile"."is_superuser", "zerver_userprofile"."email", "zerver_userprofile"."is_staff", "zerver_userprofile"."is_active", "zerver_userprofile"."is_bot", "zerver_userprofile"."date_joined", "zerver_userprofile"."bot_owner_id", "zerver_userprofile"."full_name", "zerver_userprofile"."short_name", "zerver_userprofile"."pointer", "zerver_userprofile"."last_pointer_updater", "zerver_userprofile"."realm_id", "zerver_userprofile"."api_key", "zerver_userprofile"."enable_desktop_notifications", "zerver_userprofile"."enable_sounds", "zerver_userprofile"."enter_sends", "zerver_userprofile"."enable_offline_email_notifications", "zerver_userprofile"."last_reminder", "zerver_userprofile"."rate_limits", "zerver_userprofile"."avatar_source", "zerver_userprofile"."tutorial_status", "zerver_userprofile"."onboarding_steps", "zerver_userprofile"."invites_granted", "zerver_userprofile"."invites_used", "zerver_userprofile"."alert_words", "zerver_userprofile"."muted_topics", "zerver_client"."id", "zerver_client"."name"
Now it queries just the fields it needs:
"zerver_client"."name", "zerver_userpresence"."status", "zerver_userpresence"."timestamp", "zerver_userprofile"."email" FROM "zerver_userpresence"
Also, get_status_dict_by_realm is now namespaced under UserPresence as a static method.

These engagement data will be useful both for making pretty graphs of
how addicted our users are as well as for allowing us to check whether
a new deployment is actually using the product or not.
This measures "number of minutes during which each user had checked
the app within the previous 15 minutes". It should correctly not
count server-initiated reloads.
It's possible that we should use something less aggressive than
mousemove; I'm a little torn on that because you really can check the
app for new messages without doing anything active.
This is somewhat tested but there are a few outstanding issues:
* Mobile apps don't report these data. It should be as easy as having
them send in update_active_status queries with new_user_input=true.
* The semantics of this should be better documented (e.g. the
management script should print out the spec above)x.

This cache was created to make recipient lookups within a single
request (e.g. when fetching old messages) cheaper. To support stream
name changes, we need to invalidate this cache on every request so
that users get a consistent view of the name change.

This is experimental, for staging only. There might be a better
way to model this than dueling force_expand/force_collapse flags,
but it works for now. The code in collapse_recipient_group()
could also be DRYed up relative to expand_summary_row().

This change will allow us to test the muting feature on
staging. Any topic named "muted" will automatically be
muted. You can also mute any other topic on the console:
muting.mute_topic('devel', 'ios');
current_msg_list.rerender();
More UI around this experiment will be coming soon, as well
as support for muting entire streams.
The muting module keeps track of which topics are muted, but a
user can expand muted messages, and once that happens, the
messages are marked with the "force_expand" flag that gets
persisted to the back end.
Muted messages are rendered in similar fashion to the summarized
rows, and as part of unifying some of that code, we have
made it so that expanding a summarized section doesn't remove
individual flags related to summaries; instead, the messages
get the force_expand flag set.

This commit CANNOT be deployed until the previous schema change
([schema] models: add an email_token field to Streams) is on prod.
Before applying this schema change, run the populate-stream-tokens
management command to generate tokens for streams that need them.

We now show a list of users and allow you to deactivate a user using the
same process as `python manage.py deactivate_user`.
We add a new menu item accessible from the gear icon which will eventually
have much more than just this, but we have a good start here.
Here we also add a property to UserProfile which determines whether you're
eligible to access the administration panel, and then have code which shows
the menu option if so.
This introduces a new JS file, admin.js.

The e-mail forwarder will use this. Set it to nullable temporarily to
accomodate existing streams; later commits will a) provide a script to
give all streams a token, and b) make the field non-null.
Realm administrators will eventually have a UI to regenerate stream
tokens.

It will have new callers soon and that's as fine a place as any to
avoid circular imports.

When you read messages in a narrow and then un-narrow, collapse
adjacent messages read in the narrow into a summary row that can
be clicked to expand those messages.
Scoped to staging with feature flags.
The implementation of this within our current MessageList is rather ugly.

This needs to be deployed to both staging and prod at the same
off-peak time (and the schema migration run).
At the time it is deployed, we need to make a few changes directly in
the database:
(1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr';
(2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr';
