Sumanth V Rao 0ecf5d0e83 settings_playground: Add UI to list all playgrounds.
Adds a setting UI to list all configured playgrounds
in a realm. The filter functionality can be used to
search playgrounds by its name or language.

Default sort is provided on the 'pygments_language'
field.

Front tests added to maintain server_event_dispatch
coverage. The `settings_playgrounds.js` file is added
to coverage exclusion list since it is majorly UI
based and will be tested using puppeteer tests (in
following commits).

Sumanth V Rao 32390e0c87 playgrounds: Hook up configured playgrounds to be used in code blocks.
To prevent breaking of the hardcoded playgrounds, we resort
to checking if realm_playgrounds is empty and falling back
to the hard-coded list if so. This logic is removed in the
followup commit which introduces the UI to add a playground.

Steve Howell 173ce9a3fc refactor: Use sub_store for get/validation.
This reduces the complexity of our dependency graph.

It also makes sub_store.get parallel to message_store.get.
For both you pass in the relevant id to get the
full validated object.

Abhijeet Prasad Bodas 3947b0c80a linkifiers: Update API to send data using dictionaries.
* This introduces a new event type `realm_linkifiers` and
a new key for the initial data fetch of the same name.
Newer clients will be expected to use these.

* Backwards compatibility is ensured by changing neither
the current event nor the /register key. The data which
these hold is the same as before, but internally, it is
generated by processing the `realm_linkifiers` data.
We send both the old and the new event types to clients
whenever the linkifiers are changed.
Older clients will simply ignore the new event type, and
vice versa.

* The `realm/filters:GET` endpoint (which returns tuples)
is currently used by none of the official Zulip clients.
This commit replaces it with `realm/linkifiers:GET` which
returns data in the new dictionary format.
TODO: Update the `get_realm_filters` method in the API
bindings, to hit this new URL instead of the old one.

* This also updates the webapp frontend to use the newer
events and keys.

sahil839 c6e553427a settings: Hide invite users link in settings overlay based on settings.
There was a bug where invite users link is shown in the Invitations
section of settings overlay, irrespective if the user is allowed to
invite or not based on the realm settings. So here we just use the
'can_invite_others_to_realm' field of page_params, that was added in
previous commit itself to hide the link accordingly.

Also added the code in server_events_dispatch.js for this field.
Though it doesn't do live update when the overlay is opened similar
to other policies like create_stream_policy, but it ensures that the
visibility of link is correct if the overlay is opened after the
settings has changed.

We should probably do the complete live update in future of the
elements related to such realm settings.

sahil839 4c8339fa8c settings: Replace invite_by_admins_policy with invite_to_realm_policy.
This commit replaces invite_by_admins_policy, which was a bool field,
with a new enum field invite_by_realm_policy.

Though the final goal is to add moderators and full members option
using COMMON_POLICY_TYPES, but this will be done in a separate
commit to make this easy for review.

Abhijeet Prasad Bodas 1de9444242 mute user: Add frontend functions to maintain data.
Muted users are stored in a map with key as user ID and
the value as the timestamp of muting.
Names can be easily fetched from existing functions
in `people.js` and hence not stored.

Steve Howell 4380fe4eaf refactor: Extract stream_settings_data.
This is mostly a pure code move.

update_calculated_fields in the dispatch code,
plus some tests that don't need them.

tushar912 5c50732008 user groups: Add remove event.
Before this we did not have remove event in server_events_dispatch.js
for the user group delete event even though server had. This was
leading to blueslip errors. Extracted the logic which was used in
 success() of channel.del for user_groups into the remove case in
server_events_dispatch. Also removed the redundant reload call as
we already do that in server events.

Steve Howell 72e0f2e901 bots: Lift render_bots calls to dispatcher code.
This is mostly a refactoring to break the unnecessary
dependency of bot_data on settings_bots.

This is a bit more than a refactoring, as I remove all
the debounced calls to render bots during the
initialization of bot_data. (The debouncing probably
meant we only rendered once, but it was still needless
work.)

We don't need to explicitly render bots during
bot_data.initialize(), which you can verify by loading
"#settings/your-bots" as the home page. It was just an
artifact of how add() was implemented.

Note that for the **admin** screen, we did not and
still do not do live updates for add/remove; we only do
it for updates. Fixing that is out of the scope of this
change. The code that was moved here affects
**personal** bot settings.

Note that the debounce code is quite fragile. See my
code comment that explains it. I don't have time to go
down the rabbit hole of a deep fix here. The puppeteer
tests would fail without the debounce, even though I
was able to eliminate the debounce in an earlier
version of this fix and see good results during manual
testing. (My testing may have just been on the "lucky"
side of the race.) I created #17743 to address this
problem.

Aman Agrawal e587c029f6 display_settings: Allow user to set default_view.
TextField is used to allow users to set long stream + topic narrow
names in the urls.

We currently restrict users to only set "all_messages" and
"recent_topics" as narrows.

This commit achieves 3 things:
* Removes recent topics as the default view which loads when
  hash is empty.
* Loads default_view when hash is empty.
* Loads default_view on pressing escape key when it is unhandled by
  other present UI elements.

NOTE: After this commit loading zulip with an empty hash will
automatically set hash to default_view.  Ideally, we'd just display
the default view without a hash, but that involves extra complexity.

One exception is when user is trying to load an overlay directly,
i.e. zulip is loaded with an overlay hash. In this case,
we render recent topics is background irrespective of default_view.

We consider this last detail to be a bug not important enough to block
adding this setting.

Abhijeet Prasad Bodas fd2bf0b31b refactor: Rename frontend muting stuff to include 'topic'.
This is a prep commit, which renames some variables
and functions involved in topic muting to include
the word "topic" in them.

This is done to have clarity when similar code
will be added as a part of the mute-user in
future commits.

Steve Howell 2edfdb4ff8 refactor: Extract bulk functions to add/remove peers.
We also streamline some of the error handling code
by doing everything up front.  This will prevent
scenarios where a single bad stream_id/user_id causes a
bunch of the same warnings in an inner loop.

Steve Howell 6cc880c858 refactor: Extract peer_data.js.
This de-clutters stream_data a bit.  Since our
peer data is our biggest performance concern,
I want to contain any optimizations to a fairly
well-focused module.

The name `peer_data` is a bit of a compromise,
since we already have `subs.js` and we use
`sub` as a variable name for stream records
throughout our code, but it's consistent with
our event nomenclature (peer/add, peer/remove)
and it's short while still being fairly easy
to find with grep.

ryanreh99 e5779c1ca0 message events: Refactor `reify_message_id` codepath.
The changes made in this commit are as follows:

* The `remove_messages` is moved to the `message_events.js`
  file from `ui.js`.

* We refactor `MessageListData.change_message_id` to no
  longer require an `opts` parameter as this function
  just returns whether we need to rerender or not.

  The blueslip error block can be removed since we made
  the change to no long defer the data updates in
  commit 3b5ba6b2c1,
  this case can no longer occur.

Steve Howell 7ff3859136 subscriber events: Change schema for peer_add/peer_remove.
We now can send an implied matrix of user/stream tuples
for peer_add and peer_remove events.

The client code basically does this:

    for stream_id in event['stream_ids']:
        for user_id in event['user_ids']:
            update_sub(stream_id, user_id)

We used to send individual events, which gets real
expensive when you are creating new streams. For
the case of copy-to-stream case, we should see
events go from U to 1, where U is the number of users
added.

Note that we don't yet fully optimize the potential
of this schema.  For adding a new user with lots
of default streams, we still send S peer_add events.

And if you subscribe a bunch of users to a bunch of
private streams, we only go from U * S to S; we can't
optimize it down to one event easily.

sahil839 a01d33353f message_list: Live update trailing bookend on stream deactivation.
We were not updating the trailing bookend on deactivation of stream
if the user was narrowed to deactivated stream and this commit fixes
this.

For subscribed streams, we just show the trailing bookend with
content as 'This stream has been deactivated' and hide the
Unsubscribe button.

For unsubscribed streams, we change the content of trailing bookend
to 'This stream has been deactivated' and hide the Subscribe button.

Fixes #15999.
