Steve Howell fa1059aa2e stream_data: Remove stream_name param from add_sub().
We just get the stream_name from the sub struct now.

This mostly affects node tests.

The only place in real code where we called add_sub()
was when we initialized data from the server.

Ryan Rehman 174b2abcfd settings: Migrate to stream_post_policy structure.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.

It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.

This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.

With many tweaks by tabbott to documentation under /help, etc.

Fixes #13616.

Steve Howell c2af2c1fd1 refactor: Extract is_subscriber_subset().
Extracting the function makes it a bit easier to
test and use in a generic way.

Also, I wanted this to live in stream_data, so that
it's easier to find if we change how we model
subscriber data.

Finally, I use _.every to do the subset check
instead of `_.difference`, since _.difference
is actually N-squared:

  _.difference = restArguments(function(array, rest) {
    rest = flatten(rest, true, true);
    return _.filter(array, function(value){
      return !_.contains(rest, value);
    });
  });

And we don't actually want to build a list only
to check that it's zero vs. nonzero length.

We now do this, which short circuits as soon
as it finds any key that is only in sub1:

    return _.every(sub1.subscribers.keys(), (key) => {
        return sub2_set.has(key);
    });

Steve Howell ee3e488e02 js: Extract FoldDict class.
We have ~5 years of proof that we'll probably never
extend Dict with more options.

Breaking the classes into makes both a little faster
(no options to check), and we remove some options
in FoldDict that are never used (from/from_array).

A possible next step is to fine-tune the Dict to use
Map internally.

Note that the TypeScript types for FoldDict are now
more specific (requiring string keys).  Of course,
this isn't really enforced until we convert other
modules to TS.

Steve Howell 631811e686 streams: Add BinaryDict for stream_data.
This should make any operation on subscribed
streams faster (we won't need to filter out
unsubscribed streams every time).

I started writing this before I realized we
had a bug where we call `subscribed_streams`
in a nested loop.

After fixing the bugs, this is not as much of
a bottleneck, but it's still a speedup in many
important places:

    * build left sidebar
    * every keystroke in search bar
    * first keystroke in making #stream_links
    * every keystroke in compose stream box

The streams settings code is kinda complicated.
It does a non-deterministic sort of the "others"
bucket when you add elements to the left panel.
They get hidden, anyway.  Our values() call now
puts subscribed streams first.  It never guaranteed
order, but putting subscribed streams first is
probably a good behavior for most situations.

Steve Howell a3512553a8 streams: Add LazySet for subscribers.
This defers O(N*S) operations, where

    N = number of streams
    S = number of subscribers per stream

In many cases we never do an O(N) operation on
a stream.  Exceptions include:

    - checking stream links from the compose box
    - editing a stream
    - adding members to a newly added stream

An operation that used to be O(N)--computing
the number of subscribers--is now O(1), and we
don't even pay O(N) on a one-time basis to
compute it (not counting the cost to build the
array from JSON, but we have to do that).

Steve Howell e804f39f0e performance: Avoid expensive call in stream_data.is_active.
Calling `set_filter_out_inactives` is expensive, since we
count up the number of subscribed streams, which iterates
through all your streams, creates a new list of subscribed
streams, then counts them.

In my dev setup, I created 700 streams, and this shaved
about 700ms off of the initial call to `build_stream_list`.

Nat1405 d5f005fd61 wildcard_mentions_notify: Add per-stream override of global setting.
Adds required API and front-end changes to modify and read the
wildcard_mentions_notify field in the Subscription model.

It includes front-end code to add the setting to the user's "manage
streams" page. This setting will be greyed out when a stream is muted.
The PR also includes back-end code to add the setting the initial state of
a subscription.

New automated tests were added for the API, events system and front-end.
In manual testing, we checked that modifying the setting in the front end
persisted the change in the Subscription model. We noticed the notifications
were not behaving exactly as expected in manual testing; see
https://github.com/zulip/zulip/issues/13073#issuecomment-560263081 .

Tweaked by tabbott to fix real-time synchronization issues.

potentially involving merging parts of conflicting pull requests

Harshit Bansal b553507412 subscriptions: Migrate notification setting defaults model.
This commit migrates the Subscription's notification fields from a
BooleanField to a NullBooleanField where a value of None means to
inherit the value from user's profile.

Also includes a migrations to set the corresponding settings to None
if they match the user profile's values. This migration helps us in
getting rid of the weird "Apply to all" widget that we offered on
subscription settings page.

The mobile apps can't handle None appearing as the stream-level
notification settings, so for backwards-compatibility we arrange to
only send True/False to the mobile apps by applying those defaults
server-side.  We introduce a notification_settings_null value within a
client_capabilities structure that newer versions of the mobile apps
can use to request the new model.

This mobile compatibility code is pretty effectively tested by the
existing test_events tests for the subscriptions subsystem.

This makes the "more topics" option which appears below the list of

are actually more topics to be displayed.  Two specific cases it
resolves completely include:

* Newly created realms; this widget was a common source of confusion
  for new organization administrators.
* Newly created streams.

There are still some corner cases this doesn't handle, e.g. if you
just joined a private stream with protected history, but there isn't
as easy a fix for those.

Essentially rewritten by tabbott to fix code duplication and comment
extensively.

The stream_list test that was fixed here was sort of
broken.  It accomplished the main goal of verifying
what gets rendered, but now the data setup part is
more like the actual app code (and simpler, too).

Tim Abbott 838dd6d273 lint: Add eslint enforcement for comma-spacing.
We've been enforcing this manually for a long time, and hadn't
realized it was missing from our eslint configuration.

Steve Howell d8c8fc1f03 streams: Optimize stream_data.create_sub_from_server_data.
This is definitely a micro-optimization, but avoiding
creating an extra object speeds up page loads by about
20ms per 1000 streams.

It's slightly sketchy to mutate the value in place, but
the original value never gets used again.

Steve Howell ba243416e3 stream_color: Make stream color assignment more efficient.
We now let color_data keep its own state for
unused_colors, so that we longer have to pass in
a large list of unused_colors every time we want
to assign a new stream color.

This mostly matters at startup, where we might
be cycling through 5000 streams.  We claim all
the unused colors up front.

Each operation now has an upper bound of expensiveness,
where the worst case scenario is basically popping
off the first element of a list of <= 24 colors.

The algorithm is now deterministic, too, to make
it easier to test.  It's unclear whether random color
assignment ever had much benefit, and it made unit
testing the algorithm difficult.  Now we have 100%
line coverage.

Fixes part of #10902.

Steve Howell 6035304619 Extract color_data.js.
This code is pretty distinct from all the color-picking UI,
and we want to get it to 100% coverage and optimize it
more.
