Sahil Batra ae72151ec1 streams: Pass stream_weekly_traffic field in stream objects.
This commit adds code to pass stream traffic data using
the "stream_weekly_traffic" field in stream objects.

We already include the traffic data in Subscription objects,
but the traffic data does not depend on the user to stream
relationship and is stream-only information, so it's better
to include it in Stream objects. We may remove the traffic
data and other stream information fields for Subscription
objects in future.

This will help clients to correctly display the stream
traffic data in case where client receives a stream
creation event and no subscription event, for an already
existing stream which the user did not have access to before.

Sahil Batra 2533e64be6 streams: Remove get_client_data function.
This commit changes the code to not use get_client_data
function and instead use `stream_to_dict` function to
get the stream data in a dictionary form. This is a
prep commit add stream traffic data to Stream objects.

Steve Howell adb548c7a2 stream creation: Avoid stream.realm references.
We want to avoid Django going back to the database to
get a realm object that the caller already has.

It's actually currently the case that we often
pre-fetch realm objects when we get stream objects
using get_stream (using a call to select_related() with
no arguments), but that is an expensive operation that
we want to avoid going forward.

This commit prepares us to just fetch slim objects.

Steve Howell 763b5e0741 default streams: Extract library functions.
I created zerver/lib/default_streams.py, so that various
views and events.py don't have to awkwardly reach into
an "actions" file.

I copied over two functions verbatim from actions/default_streams.py:

    get_default_streams_for_realm
    streams_to_dicts_sorted

The latter only remains as an internal detail in the new library.

I also created two new helpers:

    get_default_stream_ids_for_realm:

        This is both faster and easier to use in all the places
        where we only need to get a set of default stream ids.

    get_default_streams_for_realm_as_dicts:

        This just wraps the prior calls to
        streams_to_dicts_sorted(get_default_streams_for_realm(...)),
        and it doesn't yet address the slowness of the underlying
        code.

        All the "real" code should be functionally the same.

        In a few tests I now use this wrapper instead of
        calling get_default_streams_for_realm, just to get
        slightly deeper coverage.

Prakhar Pratyush 0b2fe5b163 user_topics: Rename the 'zerver/lib/user_topics' functions.
This is a prep commit that renames lib functions
so that they can be used while implementing view
for the new endpoint 'POST /user_topics'.

We use a more generic name when removing the visibility_policy of
a topic, i.e., 'access_stream_to_remove_visibility_policy_by_id/name'
instead of 'access_stream_for_unmute_topic_by_id/name' which focused
on removing MUTE from a topic.

This change is done as we would not be moving forward with the
stream administrator concept as we have decided to modify the
permissions model as per #19525.

Eeshan Garg 0d99809fd3 streams: Add notifications for permission policy changes.
The change to curl_param_value_generators.py warrants a brief
explanation. Stream permission changes now generate a notification
message. Our curl example test for removing a reaction comes after
the two tests for updating the stream permission changes, thus the
hardcoded message ID in that test needs to be incremented by 2 to
account for the two notification messages that now come before it.

Tim Abbott e556481ba0 streams: Remove duplicates of get_web_public_streams_queryset.
This is a somewhat subtle function, that deserves a few comments
explaining subtle details of its logic, and there's no good reason to
have multiple copies of that logic that are slightly inconsistent.

Because the main changes here are just checking for invariant
failures, the behavioral change here should be limited to ensuring
deactivated streams are not considered available even if they were
tagged as web public streams before deactivation.

Mateusz Mandera 6e11754642 CVE-2021-30478: Prevent API super users from forging messages to other organizations.
A bug in the implementation of the can_forge_sender permission
(previously is_api_super_user) resulted in users with this permission
being able to send messages appearing as if sent by a system bots,
including to other organizations hosted by the same Zulip installation.

- The send message API had a bug allowing an api super user to
  use forging to send messages to other realms' streams, as a
  cross-realm bot. We fix this most directly by eliminating the
  realm_str parameter - it is not necessary for any valid current use
  case. The email gateway doesn't use this API despite the comment in
  that block suggesting otherwise.
- The conditionals inside access_stream_for_send_message are changed up
  to improve security. They were generally not ordered very well,
  allowing the function to successfully return due to very weak
  acceptance conditions - skipping the higher importance checks that
  should lead to raising an error.
- The query count in test_subs is decreased because
  access_stream_for_send_message returns earlier when doing its check
  for a cross-realm bot sender - some subscription checking queries are
  skipped.
- A linkifier test in test_message_dict needs to be changed. It didn't
  make much sense in the first place, because it was creating a message
  by a normal user, to a stream outside of the user's realm. That
  shouldn't even be allowed.

sahil839 1ffcb0f8b9 streams: Raise same error for all values of create_stream_policy.
We keep the error message same for all cases when a user is not
allowed to create streams for all values of create_stream_policy.

We raise error with different message for guest cases because it
is handled by decorators. We aim to change this behavior in future.

Explaining the details in error message isn't much important as
we do not show errors probably in API only, as we do not the show
the options itself in the frontend.
