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.

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 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.

There is a scenario where we call process_read_message()
for a message that we haven't recorded as unread before.
I'm not sure how it happens, but I put back code to
guard against crashing. The regression happened in
5752458c821.

We have been persisting muting preferences on the back end for
a while, but we haven't been adding them to page_params for the
client to have at reload/startup time.

The indirection was more confusing than helpful, especially
since the function had side effects, despite its getter-like
name.

Empirically, we only get these for malformed emails where the charset
specified in a message part header does not match the true encoding of
the part. I checked what the resulting Zulip looked like for the
original offender, and it looked find with ignoring errors.

We now bulk-fetch subscription information once from the database
and use it throughout bulk_add_subscriptions in order to avoid
hitting the db O(streams) times.
On my machine this shaved the accounts_register API call from making
66 queries to making 37 queries.

We have a handy bulk_add_subscriptions function to make cases
like this fast, so lets use it.
On my machine this reduces the number of db queries during account_register
from 112 to 66.

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.
