Properly parse event_fields in filters (#15607)
The event_fields property in filters should use the proper
escape rules, namely backslashes can be escaped with
an additional backslash.

This adds tests (adapted from matrix-js-sdk) and implements
the logic to properly split the event_fields strings.

Implement MSC3821 to update redaction rules (third_party_invite.signed) (#15563)
Updates the redaction rules to protect enough information that the
event can still be properly verified.

Implement MSC3389 to protect relations from redaction. (#15565)
MSC3389 proposes protecting the relation type & parent event ID
from redaction. This keeps the relation information intact after
redaction which helps with some UX flaws (e.g. deleting an
event causes it to no longer be in a thread, which is confusing).

Stop applying edits to event contents (MSC3925). (#15193)
Enables MSC3925 support by default, which:

* Includes the full edit event in the bundled aggregations of an
  edited event.
* Stops modifying the original event's content to return the new
  content from the edit event.

This is a backwards-incompatible change that is considered to be
"correct" by the spec.

Remove support for aggregating reactions (#15172)
It turns out that no clients rely on server-side aggregation of `m.annotation`
relationships: it's just not very useful as currently implemented.

It's also non-trivial to calculate.

I want to remove it from MSC2677, so to keep the implementation in line, let's
remove it here.

Reject boolean power levels (#14944)
* Better test for bad values in power levels events

The previous test only checked that Synapse didn't raise an exception,
but didn't check that we had correctly interpreted the value of the
dodgy power level.

It also conflated two things: bad room notification levels, and bad user
levels. There _is_ logic for converting the latter to integers, but we
should test it separately.

* Check we ignore types that don't convert to int

* Handle `None` values in `notifications.room`

* Changelog

* Also test that bad values are rejected by event auth

Implement MSC3925: changes to bundling of edits (#14811)
Two parts to this:

 * Bundle the whole of the replacement with any edited events. This is backwards-compatible so I haven't put it behind a flag.
 * Optionally, inhibit server-side replacement of edited events. This has scope to break things, so it is currently disabled by default.

Include bundled aggregations for the latest event in a thread. (#12273)
The `latest_event` field of the bundled aggregations for `m.thread` relations
did not include bundled aggregations itself. This resulted in clients needing to
immediately request the event from the server (and thus making it useless that
the latest event itself was serialized instead of just including an event ID).

Improvements to bundling aggregations. (#11815)
This is some odds and ends found during the review of #11791
and while continuing to work in this code:

* Return attrs classes instead of dictionaries from some methods
  to improve type safety.
* Call `get_bundled_aggregations` fewer times.
* Adds a missing assertion in the tests.
* Do not return empty bundled aggregations for an event (preferring
  to not include the bundle at all, as the docstring states).

Bundle aggregations outside of the serialization method. (#11612)

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

* 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

* 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

* Fix federated events being rejected for no state_groups

Add fix from https://github.com/matrix-org/synapse/pull/10439
until it merges.

* Only connect base insertion event to prev_event_ids

Per discussion with @erikjohnston,
https://matrix.to/#/!UytJQHLQYfvYWsGrGY:jki.re/$12bTUiObDFdHLAYtT7E-BvYRp3k_xv8w0dUQHibasJk?via=jki.re&via=matrix.org

* Make it possible to get the room_version with txn

* Allow but ignore historical events in unsupported room version

See https://github.com/matrix-org/synapse/pull/10245#discussion_r675592489

We can't reject historical events on unsupported room versions because homeservers without knowledge of MSC2716 or the new room version don't reject historical events either.

Since we can't rely on the auth check here to stop historical events on unsupported room versions, I've added some additional checks in the processing/persisting code (`synapse/storage/databases/main/events.py` ->  `_handle_insertion_event` and `_handle_chunk_event`). I've had to do some refactoring so there is method to fetch the room version by `txn`.

* Move to unique index syntax

See https://github.com/matrix-org/synapse/pull/10245#discussion_r675638509

* High-level document how the insertion->chunk lookup works

* Remove create_event fallback for room_versions

See https://github.com/matrix-org/synapse/pull/10245/files#r677641879

* Use updated method name

Ensure we use a copy of the event content dict before modifying it in serialize_event (#9585)
This bug was discovered by DINUM. We were modifying `serialized_event["content"]`, which - if you've got `USE_FROZEN_DICTS` turned on or are [using a third party rules module](17cd48fe51/synapse/events/third_party_rules.py (L73-L76)) - will raise a 500 if you try to a edit a reply to a message.

`serialized_event["content"]` could be set to the edit event's content, instead of a copy of it, which is bad as we attempt to modify it. Instead, we also end up modifying the original event's content. DINUM uses a third party rules module, which meant the event's content got frozen and thus an exception was raised.

To be clear, the problem is not that the event's content was frozen. In fact doing so helped us uncover the fact we weren't copying event content correctly.

Rather than relying on `outlier` being in the `internal_metadata` column,
populate it based on the `events.outlier` column.

* Move `outlier` out of InternalMetadata._dict

Ultimately, this will allow us to stop writing it to the database. For now, we
have to grandfather it back in so as to maintain compatibility with older
versions of Synapse.
