Tim Abbott 66b29fbb8c streams: Centralize logic for computing stream permissions.
I found the previous model for computing what settings to use for
streams increasingly difficult to understand, which is generally a
recipe for future bugs.

Refactor to have a clear computation of what complete permissions
state the client is requesting, validate that state, and then pass
that state to the do_change_stream_permission.

Sahil Batra 3e6463804e streams: Allow changing history access without is_private parameter.
We now allow changing access to history of the stream by only passing
"history_public_to_subscribers" parameter. Previously, "is_private"
parameter was also required to change history_public_to_subscribers
otherwise the request was silently ignored.

We also raise error when only history_public_to_subscribers parameter
is passed with value False without "is_private: True" for a public
or web-public stream since we do not allow public streams with
protected history.

Sahil Batra 6ccfebac56 streams: Raise error when making public stream with private history.
We raise error when we try to change a public stream (except for
zephyr mirror realms) to be public with protected history, as we do
not support such streams yet.

Previously, in such case we changed nothing and a notification was
sent to the "stream events" topic with message being "stream is
changed from public to public" and was weird.

Note that this commit only handles the case when both is_private and
history_public_to_subscribers parameters are passed to API and commit
not covers the case when only "history_public_to_subscribers" with
value False is passed to API, since we currently ignore requests
which has only history_public_to_subscribers parameter with not None
and not is_private and is_web_public.
We would do this in further commits when we add support for accepting
only history_public_to_subscribers parameter.

Sahil Batra 52c8f687cc streams: Rename admin_access_required to unsubscribing_others.
This commit renames admin_access_required parameter of
list_to_streams function to unsubscribing_others since that
parameter is used and passed as True only when calling
the function while unsubscribing others and in further
commits we would allow non-admins too to unsubscribe others
based on can_remove_subscribers_group setting.

Tim Abbott c789097184 streams: Fix empty description handling in new stream notifications.

Tim Abbott d693a6717c i18n: Remove quote syntax from stream description notification.
Translators found it confusing, since it's not at all obvious that the
word "quote" should not be translated.

I'm not altogether happy with the code formatting for this.

While we're changing this, also standardize on the "```` quote" style
of quote blocks to ensure code/quote blocks in stream descriptions are
unlikely to conflict with this syntax.

Lauryn Menard 3be622ffa7 backend: Add request as parameter to json_success.
Adds request as a parameter to json_success as a refactor towards

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.

This is a part of #20289.

Eeshan Garg c30458e174 streams: Add notifications for posting policy changes.
An explanatory note on the changes in zulip.yaml and
curl_param_value_generators is warranted here. In our automated
tests for our curl examples, the test for the API endpoint that
changes the posting permissions of a stream comes before our
existing curl test for adding message reactions.

Since there is an extra notification message due to the change in
posting permissions, the message IDs used in tests that come after
need to be incremented by 1.

This is a part of #20289.

Steve Howell c4bd4496dd peformance: Cache user mentions for multiple PMs.
It's slightly annoying to plumb Optional[MentionBackend]
down the stack, but it's a one-time change.

I tried to make the cache code relatively unobtrusive
for the single-message use case.

We should be able to eliminate redundant stream queries
using similar techniques.

I considered caching at the level of rendering the message
itself, but this involves nearly as much plumbing, and
you have to account for the fact that several users on
your realm may have distinct default languages (French,
Spanish, Russian, etc.), so you would not eliminate as
many query hops. Also, if multiple streams were involved,
users would get slightly different messages based on
their prior subscriptions.

Eeshan Garg 3714a30e63 stream notifications: Add helper for silent user mention syntax.
In many of our stream notification messages, we make use of the

callers can call to get the right syntax when mentioning users.

Thanks to Tim Abbott for this suggestion!

Lauryn Menard 7713b371a5 api: Migrate `/update-subscription-settings` response value.
Migrates the `/update-subscription-settings` api endpoint to the
`ignored_parameters_unsupported` model, which is also currently used
by `/update-settings` and `update-realm-user-settings-defaults`.

This change is a step towards preparing for an eventual migration to
have all endpoints return an `ignored_parameters_unsupported` block.

Previously the `/update-subscription-settings` endpoint returned a
copy of the data object sent in the request.

Fixes #15307.

Tim Abbott 95606a7347 api: Return user IDs, not display emails, in subscribers endpoints.
Sometime in the deep past, Zulip the GET /users/me/subscriptions
endpoint started returning subscribers.  We noticed this and made it
optional via the include_subscribers parameter in
1af72a2745, however, we didn't notice
that they were being returned as emails rather than user IDs.

We migrated the core /register code paths to use subscriber IDs years
ago; this change completes that for the endpoints we forgot about.

The documentation allowed this error because we apparently had no
tests for this code path that used the actual API.

PIG208 dcbb2a78ca python: Migrate most json_error => JsonableError.
JsonableError has two major benefits over json_error:
* It can be raised from anywhere in the codebase, rather than
  being a return value, which is much more convenient for refactoring,
  as one doesn't potentially need to change error handling style when
  extracting a bit of view code to a function.
* It is guaranteed to contain the `code` property, which is helpful
  for API consistency.

Various stragglers are not updated because JsonableError requires
subclassing in order to specify custom data or HTTP status codes.

Abhijeet Prasad Bodas 5f4113cf60 message delete: Select Message FOR UPDATE when archiving.
Further commits will start locking the message rows while
adding related fields like reactions or submessages,
to handle races caused by deleting the message itself at the
same time.

The message locking implemented then will create a possibility
of deadlocks, where the related field transaction holds a lock
on the message row, and the message-delete transaction holds a
lock on the database row of the related field (which will also
need to be deleted when the message is deleted), and both
transactions wait for each other.

To prevent such a deadlock, we lock the message itself while
it is being deleted, so that the message-delete transaction
will have to wait till the other transaction (which is about
to delete the related field, and also holds a lock on the
message row) commits.
