And fix a bug in the implementation of the updated redaction
format (MSC2174) where the top-level redacts field was not
properly added for backwards-compatibility.
Allow configuring the set of workers to proxy outbound federation traffic through (`outbound_federation_restricted_to`).
This is useful when you have a worker setup with `federation_sender` instances responsible for sending outbound federation requests and want to make sure *all* outbound federation traffic goes through those instances. Before this change, the generic workers would still contact federation themselves for things like profile lookups, backfill, etc. This PR allows you to set more strict access controls/firewall for all workers and only allow the `federation_sender`'s to contact the outside world.
**Before:**
```
Error retrieving alias
```
**After:**
```
Error retrieving alias #foo:bar -> 401 Unauthorized
```
*Spawning from creating the [manual testing strategy for the outbound federation proxy](https://github.com/matrix-org/synapse/pull/15773).*
Unix socket support for `federation` and `client` Listeners has existed now for a little while(since [1.81.0](https://github.com/matrix-org/synapse/pull/15353)), but there was one last hold out before it could be complete: HTTP Replication communication. This should finish it up. The Listeners would have always worked, but would have had no way to be talked to/at.

A lot of the functions have the same name in this space like `store_file`,
and we also do it multiple times for different reasons (main media repo,
other storage providers, thumbnails, etc) so it's good to differentiate
them so your head doesn't explode.

The original code is from @erikjohnston's branches which I've gotten in-shape to merge.
Image.ANTIALIAS is not defined in current pillow releases. Since ANTIALIAS was just using LANCZOS anyways, this is just a cosmetic change, but makes synapse work with most recent pillow releases.

Old device entries for the same user were being removed in individual
SQL commands, making the batch take way longer than necessary.
This combines the commands into a single one with a IN/ANY clause.
Example of log entry before the change, regularly observed with
"log_min_duration_statement = 10000" in PostgreSQL's config:
LOG: duration: 42538.282 ms statement:
DELETE FROM device_lists_stream
WHERE user_id = '@someone' AND device_id = 'someid1'
AND stream_id < 123456789
;
DELETE FROM device_lists_stream
WHERE user_id = '@someone' AND device_id = 'someid2'
AND stream_id < 123456789
;
[repeated for each device ID of that user, potentially a lot...]
With the patch applied on my instance for the past couple of days, I
no longer notice overly long statements of that particular kind.

If you leave a room and forget it, then rejoin it, the room would be
missing from the next initial sync.

The port DB script would try and run database background tasks, which
could fail if the data they acted on was in the process of being ported.
These exceptions were non fatal.
Fixes#15789
We now only block the client to backfill when we see a large gap in the events (more than 2 events missing in a row according to `depth`), more than 3 single-event holes, or not enough messages to fill the response. Otherwise, we return the messages directly to the client and backfill in the background for eventual consistency sake.
Fix https://github.com/matrix-org/synapse/issues/15696
* Check required power levels earlier in createRoom handler.
- If a server was configured to reject the creation of rooms with E2EE
enabled (by specifying an unattainably high power level for
"m.room.encryption" in default_power_level_content_override), the 403
error was not being triggered until after the room was created and
before the "m.room.power_levels" was sent. This allowed a user to
access the partially-configured room and complete the setup of E2EE
and power levels manually.
- This change causes the power level overrides to be checked earlier and
the request to be rejected before the user gains access to the room.
- A new `_validate_room_config` method is added to contain checks that
should be run before a room is created.
- The new test case confirms that a user request is rejected by the new
validation method.

There appears to be a race where you can end up with entries in
`event_push_summary` with both a `NULL` and `main` thread ID.

This is useful because when see that a relevant event is an `outlier` or `soft-failed`, then that's a good unexpected indicator explaining why it's not showing up. `filter_events_for_client` is used in `/sync`, `/messages`, `/context` which are all common end-to-end assertion touch points (also notifications, relations).
Implements stable support for MSC3882; this involves updating Synapse's support to
match the MSC / the spec says.
Continue to support the unstable version to allow clients to transition.
The stubs have some issues so this has some generous cast
and ignores in it, but it is better than not having stubs.
Note that confusing that Element is a function which creates
_Element instances (and similarly for Comment).
