Correctly include room avatars in email notifications (#10658)
Judging by the template, this was intended ages ago, but we never
actually passed an avatar URL to the template. So let's provide one.

Closes #1546.

Skip the final GC on shutdown to improve restart times (#10712)
Use `gc.freeze()` on exit to exclude all existing objects from the final GC.
In testing, this sped up shutdown by up to a few seconds.

`gc.freeze()` runs in constant time, so there is little chance of performance
regression.

Fix incompatibility with Twisted < 21. (#10713)
Turns out that the functionality added in #10546 to skip TLS was incompatible
with older Twisted versions, so we need to be a bit more inventive.

Also, add a test to (hopefully) not break this in future. Sadly, testing TLS is
really hard.

Fix perf of fetching the same events many times. (#10703)
The code to deduplicate repeated fetches of the same set of events was
N^2 (over the number of events requested), which could lead to a process
being completely wedged.

The main fix is to deduplicate the returned deferreds so we only await
on a deferred once rather than many times. Seperately, when handling the
returned events from the defrered we only add the events we care about
to the event map to be returned (so that we don't pay the price of
inserting extraneous events into the dict).

Make backfill and get_missing_events use the same codepath (#10645)
Given that backfill and get_missing_events are basically the same thing, it's somewhat crazy that we have entirely separate code paths for them. This makes backfill use the existing get_missing_events code, and then clears up all the unused code.

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it eagerly and just update it if it gets outdated.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`.

Centralise the custom template directory (#10596)
Several configuration sections are using separate settings for custom template directories, which can be confusing. This PR adds a new top-level configuration for a custom template directory which is then used for every module. The only exception is the consent templates, since the consent template directory require a specific hierarchy, so it's probably better that it stays separate from everything else.

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

In places where we log event objects, knowing whether or not you're dealing
with an outlier is super useful.

* 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

Convert Transaction and Edu object to attrs (#10542)
Instead of wrapping the JSON into an object, this creates concrete
instances for Transaction and Edu. This allows for improved type
hints and simplified code.

Clean up federation event auth code (#10539)
* drop old-room hack

pretty sure we don't need this any more.

* Remove incorrect comment about modifying `context`

It doesn't look like the supplied context is ever modified.

* Stop `_auth_and_persist_event` modifying its parameters

This is only called in three places. Two of them don't pass `auth_events`, and
the third doesn't use the dict after passing it in, so this should be non-functional.

* 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`

Rename `auth_events` parameter to better reflect what it contains.

* Improve documentation on `_NewEventInfo`

* Improve documentation on `_check_event_auth`

rename `auth_events` parameter to better describe what it contains

* changelog

Update the API response for spaces summary over federation. (#10530)
This adds 'allowed_room_ids' (in addition to 'allowed_spaces', for backwards
compatibility) to the federation response of the spaces summary.

A future PR will remove the 'allowed_spaces' flag.

Add a setting to disable TLS for sending email (#10546)
This is mostly useful in case the server offers TLS, but doesn't present a valid certificate.

Refactoring before implementing the updated spaces summary. (#10527)
This should have no user-visible changes, but refactors some pieces of
the SpaceSummaryHandler before adding support for the updated
MSC2946.

Only return an appservice protocol if it has a service providing it. (#10532)
If there are no services providing a protocol, omit it completely
instead of returning an empty dictionary.

This fixes a long-standing spec compliance bug.

Send unstable-prefixed room_type in store-invite IS API requests (#10435)
The room type is per MSC3288 to allow the identity-server to
change invitation wording based on whether the invitation is to
a room or a space.

The prefixed key will be replaced once MSC3288 is accepted
into the spec.

Add support for MSC2716 marker events (#10498)
* Make historical messages available to federated servers

Part of MSC2716: https://github.com/matrix-org/matrix-doc/pull/2716

Follow-up to https://github.com/matrix-org/synapse/pull/9247

* Debug message not available on federation

* Add base starting insertion point when no chunk ID is provided

* Fix messages from multiple senders in historical chunk

Follow-up to https://github.com/matrix-org/synapse/pull/9247

Part of MSC2716: https://github.com/matrix-org/matrix-doc/pull/2716

---

Previously, Synapse would throw a 403,
`Cannot force another user to join.`,
because we were trying to use `?user_id` from a single virtual user
which did not match with messages from other users in the chunk.

* Remove debug lines

* Messing with selecting insertion event extremeties

* Move db schema change to new version

* Add more better comments

* Make a fake requester with just what we need

See https://github.com/matrix-org/synapse/pull/10276#discussion_r660999080

* Store insertion events in table

* Make base insertion event float off on its own

See https://github.com/matrix-org/synapse/pull/10250#issuecomment-875711889

Conflicts:
	synapse/rest/client/v1/room.py

* Validate that the app service can actually control the given user

See https://github.com/matrix-org/synapse/pull/10276#issuecomment-876316455

Conflicts:
	synapse/rest/client/v1/room.py

* Add some better comments on what we're trying to check for

* Continue debugging

* Share validation logic

* Add inserted historical messages to /backfill response

* Remove debug sql queries

* Some marker event implemntation trials

* Clean up PR

* Rename insertion_event_id to just event_id

* Add some better sql comments

* More accurate description

* Add changelog

* Make it clear what MSC the change is part of

* Add more detail on which insertion event came through

* Address review and improve sql queries

* Only use event_id as unique constraint

* Fix test case where insertion event is already in the normal DAG

* Remove debug changes

* Add support for MSC2716 marker events

* Process markers when we receive it over federation

* WIP: make hs2 backfill historical messages after marker event

* hs2 to better ask for insertion event extremity

But running into the `sqlite3.IntegrityError: NOT NULL constraint failed: event_to_state_groups.state_group`
error

* Add insertion_event_extremities table

* Switch to chunk events so we can auth via power_levels

Previously, we were using `content.chunk_id` to connect one
chunk to another. But these events can be from any `sender`
and we can't tell who should be able to send historical events.
We know we only want the application service to do it but these
events have the sender of a real historical message, not the
application service user ID as the sender. Other federated homeservers
also have no indicator which senders are an application service on
the originating homeserver.

So we want to auth all of the MSC2716 events via power_levels
and have them be sent by the application service with proper
PL levels in the room.

* Switch to chunk events for federation

* Add unstable room version to support new historical PL

* Messy: Fix undefined state_group for federated historical events
