I'm pretty sure this code was a hack to workaround the fact that
without database-level autocommit, .get_or_create is racy.

This was a precursor to UserMessage.flags.read that never got used
because we decided to use django-bitfield.

Here we introduce a new Django app, zilencer. The intent is to not have
this app enabled on LOCALSERVER instances, and for it to grow to include
all the functionality we want to have in our central server that isn't
relevant for local deployments.
Currently we have to modify functions in zerver/* to match; in the
future, it would be cool to have the relevant shared code broken out
into a separate library.
This commit inclues both the migration to create the models as well as a
data migration that (for non-LOCALSERVER) creates a single default
Deployment for zulip.com.
To apply this migration to your system, run:
./manage.py migrate zilencer

This has a small bug where we don't actually filter the message out of
the home view; fixing that requires adding an index on the "flags"
field of UserMessage.

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
code after registering for remote notifications

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 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.
