Add some assertions about outliers (#10773)
I think I have finally teased apart the codepaths which handle outliers, and those that handle non-outliers. 
Let's add some assertions to demonstrate my newfound knowledge.

Persist auth events before the events that rely on them (#10771)
If we're persisting an event E which has auth_events A1, A2, then we ought to make sure that we correctly auth
and persist A1 and A2, before we blindly accept E.

This PR does part of that - it persists the auth events first - but it does not fully solve the problem, because we
still don't check that the auth events weren't rejected.

Return stripped m.space.child events via the space summary. (#10760)
The full event content cannot be trusted from this API (as no auth
chain, etc.) is processed over federation. Returning the full event
content was a bug as MSC2946 specifies that only the stripped
state should be returned.

This also avoids calculating aggregations / annotations which go
unused.

Move maybe_kick_guest_users out of BaseHandler (#10744)
This is part of my ongoing war against BaseHandler. I've moved kick_guest_users into RoomMemberHandler (since it calls out to that handler anyway), and split maybe_kick_guest_users into the two places it is called.

Allow room creator to send MSC2716 related events in existing room versions (#10566)
* Allow room creator to send MSC2716 related events in existing room versions

Discussed at https://github.com/matrix-org/matrix-doc/pull/2716/#discussion_r682474869

Restoring `get_create_event_for_room_txn` from,
44bb3f0cf5

* Add changelog

* Stop people from trying to redact MSC2716 events in unsupported room versions

* Populate rooms.creator column for easy lookup

> From some [out of band discussion](https://matrix.to/#/!UytJQHLQYfvYWsGrGY:jki.re/$p2fKESoFst038x6pOOmsY0C49S2gLKMr0jhNMz_JJz0?via=jki.re&via=matrix.org), my plan is to use `rooms.creator`. But currently, we don't fill in `creator` for remote rooms when a user is invited to a room for example. So we need to add some code to fill in `creator` wherever we add to the `rooms` table. And also add a background update to fill in the rows missing `creator` (we can use the same logic that `get_create_event_for_room_txn` is doing by looking in the state events to get the `creator`).

> https://github.com/matrix-org/synapse/pull/10566#issuecomment-901616642

* Remove and switch away from get_create_event_for_room_txn

* Fix no create event being found because no state events persisted yet

* Fix and add tests for rooms creator bg update

* Populate rooms.creator field for easy lookup

Part of https://github.com/matrix-org/synapse/pull/10566

 - Fill in creator whenever we insert into the rooms table
 - Add background update to backfill any missing creator values

* Add changelog

* Fix usage

* Remove extra delta already included in #10697

* Don't worry about setting creator for invite

* Only iterate over rows missing the creator

See https://github.com/matrix-org/synapse/pull/10697#discussion_r695940898

* Use constant to fetch room creator field

See https://github.com/matrix-org/synapse/pull/10697#discussion_r696803029

* More protection from other random types

See https://github.com/matrix-org/synapse/pull/10697#discussion_r696806853

* Move new background update to end of list

See https://github.com/matrix-org/synapse/pull/10697#discussion_r696814181

* Fix query casing

* Fix ambiguity iterating over cursor instead of list

Fix `psycopg2.ProgrammingError: no results to fetch` error
when tests run with Postgres.

```
SYNAPSE_POSTGRES=1 SYNAPSE_TEST_LOG_LEVEL=INFO python -m twisted.trial tests.storage.databases.main.test_room
```

---

We use `txn.fetchall` because it will return the results as a
list or an empty list when there are no results.

Docs:

> `cursor` objects are iterable, so, instead of calling explicitly fetchone() in a loop, the object itself can be used:
>
> https://www.psycopg.org/docs/cursor.html#cursor-iterable

And I'm guessing iterating over a raw cursor does something weird when there are no results.

Previously a step was skipped causing ordering to be inconsistent with

Fix incompatibility with Twisted < 21. (#10713)

Make backfill and get_missing_events use the same codepath (#10645)

Refactor on_receive_pdu code (#10615)
* drop room pdu linearizer sooner

No point holding onto it while we recheck the db

* move out `missing_prevs` calculation

we're going to need `missing_prevs` whatever we do, so we may as well calculate
it eagerly and just update it if it gets outdated.

* Add another `if missing_prevs` condition

this should be a no-op, since all the code inside the block already checks `if
missing_prevs`

* reorder if conditions

This shouldn't change the logic at all.

* Push down `min_depth` read

No point reading it from the database unless we're going to use it.

* Collect the sent_to_us_directly code together

Move the remaining `sent_to_us_directly` code inside the `if
sent_to_us_directly` block.

* Properly separate the `not sent_to_us_directly` branch

Since the only way this second block is now reachable is if we
*didn't* go into the `sent_to_us_directly` branch, we can replace it with a
simple `else`.

Clean up some logging in the federation event handler (#10591)
* Include outlier status in `str(event)`

* Remove duplicated logging in get_missing_events

When we process events received from get_missing_events, we log them twice
(once in `_get_missing_events_for_pdu`, and once in `on_receive_pdu`). Reduce
the duplication by removing the logging in `on_receive_pdu`, and ensuring the
call sites do sensible logging.

* log in `on_receive_pdu` when we already have the event

* Log which prev_events we are missing

* Stop `_check_event_auth` modifying its parameters

`_check_event_auth` is only called in three places. `on_send_membership_event`
doesn't pass an `auth_events`, and `prep` and `_auth_and_persist_event` do not
use the map after passing it in.

* Stop `_update_auth_events_and_context_for_auth` modifying its parameters

Return the updated auth event dict, rather than modifying the parameter.

This is only called from `_check_event_auth`.

* Improve documentation on `_auth_and_persist_event`

* Improve documentation on `_NewEventInfo`

* Improve documentation on `_check_event_auth`
