Make historical events discoverable from backfill for servers without any scrollback history (MSC2716) (#10245)
* 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

* 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

* 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.

Prep work for removing `outlier` from `internal_metadata` (#9411)
* Populate `internal_metadata.outlier` based on `events` table

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.

Remove stream ordering from Metadata dict (#8452)
There's no need for it to be in the dict as well as the events table. Instead,
we store it in a separate attribute in the EventInternalMetadata object, and
populate that on load.

This means that we can rely on it being correctly populated for any event which
has been persited to the database.

Store room_versions in EventBase objects (#6875)
This is a bit fiddly because it all has to be done on one fell swoop:

* Wherever we create a new event, pass in the room version (and check it matches the format version)
* When we prune an event, use the room version of the unpruned event to create the pruned version.
* When we pass an event over the replication protocol, pass the room version over alongside it, and use it when deserialising the event again.

Mark Haines bde8d78b8a Copy rather than move the fields to shuffle between a v1 and a v2 event.
This should make all v1 APIs compatible with v2 clients. While still
allowing v1 clients to access the fields.

This makes the documentation easier since we can just document the v2
format and explain that some of the fields, in some of the APIs are
duplicated for backwards compatibility, rather than having to document
two separate event formats.
