Implement the /threads endpoint from MSC3856.
This is currently unstable and behind an experimental configuration
flag.
It includes a background update to backfill data, results from
the /threads endpoint will be partial until that finishes.
**Before:**
```
WARNING - POST-11 - Unable to parse JSON: Expecting value: line 1 column 1 (char 0) (b'')
```
**After:**
```
WARNING - POST-11 - Unable to parse JSON from POST /_matrix/client/v3/join/%21ZlmJtelqFroDRJYZaq:hs1?server_name=hs1 response: Expecting value: line 1 column 1 (char 0) (b'')
```
---
It's possible to figure out which endpoint these warnings were coming from before but you had to follow the request ID `POST-11` to the log line that says `Completed request [...]`. Including this key information next to the JSON parsing error makes it much easier to reason whether it matters or not.

Alternatively we could remove these extra logs but they are probably more usually helpful to figure out what went wrong.
Fixes two related bugs:
* No edit information was bundled for events which aren't `m.room.message`.
* `m.new_content` was not applied for those events.
* Revert to prior build-system requirements
This reverts #14080.
* Use normalised extra name, which poetry-core 1.3 will generate anyway
* Changelog
* Upper bound build-system requirements
* Remove upgrade note; expand changelog entry a little.

Fixes two related bugs:
* The handling of `[null]` for a `room_types` filter was incorrect.
* The ordering of arguments when providing both a network tuple
and room type field was incorrect.
By getting the joined rooms before the current token we avoid any reading
history to confirm a user *was* in a room. We can then use any membership
change events, which we already fetch during sync, to determine the final
list of joined room IDs.
Applies the proper logic for unthreaded and threaded receipts to either
apply to all events in the room or only events in the same thread, respectively.
When retrieving counts of notifications segment the results based on the
thread ID, but choose whether to return them as individual threads or as
a single summed field by letting the client opt-in via a sync flag.
The summarization code is also updated to be per thread, instead of per
room.
Implements MSC2832 by sending application service access
tokens in the Authorization header.
The access token is also still sent as a query parameter until
the application service ecosystem has fully migrated to using
headers. In the future this could be made opt-in, or removed
completely.
Keep the old behavior (of including the original_event field) for any
requests to the /unstable version of the endpoint, but do not include
the field when the /v1 version is used.
This should avoid new clients from depending on this field, but will
not help with current dependencies.
MSC3316 declares that both /rooms/{roomId}/send and /rooms/{roomId}/state
should accept a ts parameter for appservices. This change expands support
to /state and adds tests.
Instead of running a single large query, run a single query for
user-only lookups and additional queries for batches of user device
lookups.
Resolves#13580.

Spawned while working on [`get_users_in_room` mis-uses](https://github.com/matrix-org/synapse/pull/13958#discussion_r984074897) and thinking we could use `get_local_users_in_room` here but we can't.
From first glance, it seemed like this was only using local users from all of the `is_mine_id(user_id)` checks but I see that it does actually use remote users. Just making things a little more clear here what it does and mentions remote users so maybe that will be more obvious in the future.

We move the expensive check of visibility to after calculating push actions, avoiding the expensive check for users who won't get pushed anyway.
I think this should have a big impact on rooms with large numbers of local users that have pushed disabled.
Fixes#13942. Introduced in #13575.
Basically, let's only get the ordered set of hosts out of the DB if we need an ordered set of hosts. Since we split the function up the caching won't be as good, but I think it will still be fine as e.g. multiple backfill requests for the same room will hit the cache.
There is no need to grab thousands of backfill points when we only need 5 to make the `/backfill` request with. We need to grab a few extra in case the first few aren't visible in the history.
Previously, we grabbed thousands of backfill points from the database, then sorted and filtered them in the app. Fetching the 4.6k backfill points for `#matrix:matrix.org` from the database takes ~50ms - ~570ms so it's not like this saves a lot of time 🤷. But it might save us more time now that `get_backfill_points_in_room`/`get_insertion_event_backward_extremities_in_room` are more complicated after https://github.com/matrix-org/synapse/pull/13635
This PR moves the filtering and limiting to the SQL query so we just have less data to work with in the first place.

c.f. #12993 (comment), point 3
This stores all device list updates that we receive while partial joins are ongoing, and processes them once we have the full state.
Note: We don't actually process the device lists in the same ways as if we weren't partially joined. Instead of updating the device list remote cache, we simply notify local users that a change in the remote user's devices has happened. I think this is safe as if the local user requests the keys for the remote user and we don't have them we'll simply fetch them as normal.
This PR begins work on batching up events during the creation of a room. The PR splits out the creation and sending/persisting of the events. The first three events in the creation of the room-creating the room, joining the creator to the room, and the power levels event are sent sequentially, while the subsequent events are created and collected to be sent at the end of the function. This is currently done by appending them to a list and then iterating over the list to send, the next step (after this PR) would be to send and persist the collected events as a batch.

> Discovered while trying to make Synapse fast enough for [this MSC2716 test for importing many batches](https://github.com/matrix-org/complement/pull/214#discussion_r741678240). As an example, disabling the `have_seen_event` cache saves 10 seconds for each `/messages` request in that MSC2716 Complement test because we're not making as many federation requests for `/state` (speeding up `have_seen_event` itself is related to https://github.com/matrix-org/synapse/issues/13625)
>
> But this will also make `/messages` faster in general so we can include it in the [faster `/messages` milestone](https://github.com/matrix-org/synapse/milestone/11).

### The problem
`_invalidate_caches_for_event` doesn't run in monolith mode which means we never even tried to clear the `have_seen_event` and other caches. And even in worker mode, it only runs on the workers, not the master (AFAICT).
Additionally there was bug with the key being wrong so `_invalidate_caches_for_event` never invalidates the `have_seen_event` cache even when it does run.
Because we were using the `@cachedList` wrong, it was putting items in the cache under keys like `((room_id, event_id),)` with a `set` in a `set` (ex. `(('!TnCIJPKzdQdUlIyXdQ:test', '$Iu0eqEBN7qcyF1S9B3oNB3I91v2o5YOgRNPwi_78s-k'),)`) and we we're trying to invalidate with just `(room_id, event_id)` which did nothing.
Since MSC3715 has passed FCP, the stable parameter can be used.
This currently falls back to the unstable parameter if the stable
parameter is not provided (and MSC3715 support is enabled in
the configuration).
Since #11482, we're saving sessions IDs from upstream IdPs, but we've been losing them when the user goes through a user mapping session on account registration.
During a `lazy_load_members` `/sync`, we look through auth events in
rooms with partial state to find prior membership events. When such a
membership is not found, an error is logged.
Since the first join event for a user never has a prior membership event
to cite, the error would always be logged when one appeared in the room
timeline.
Avoid logging errors for such events.
Introduced in #13477.

This should mean that logs from worker processes are flushed before shutdown.
When a test completes, Complement stops the docker container, which means that
synapse will receive a SIGTERM. Currently, the `complement_fork_starter` exits
immediately (without notifying the worker processes), which means that the
workers never get a chance to flush their logs before the whole container is
vaped. We can fix this by propagating the SIGTERM to the children.
This is also using the partial state approximation if needed so we do
not block here during a fast join.

This moves all the invalidations into a single place and de-duplicates
the code involved in invalidating caches for a given event by using
the base class method.
* Lockfile: update canonicaljson 1.6.0 -> 1.6.3
* Fix mypy errors with latest canonicaljson
The change to `_encode_json_bytes` definition wasn't sufficient:
```
synapse/http/server.py:751: error: Incompatible types in assignment (expression has type "Callable[[Arg(object, 'json_object')], bytes]", variable has type "Callable[[Arg(object, 'data')], bytes]") [assignment]

Which I think is mypy warning us that the two functions accept different
sets of kwargs. Fair enough!

Use the provided list of servers in the room from the `/send_join`
response, since we will not know which users are in the room. This
isn't sufficient to ensure that all remote servers receive the right
device list updates, since the `/send_join` response may be inaccurate
or we may calculate the membership state of new users in the room
incorrectly.

Adds a `thread_id` column to the `event_push_actions`, `event_push_actions_staging`,
and `event_push_summary` tables. This will notifications to be segmented by the thread
in a future pull request. The `thread_id` column stores the root event ID or the special
value `"main"`.
The `thread_id` column for `event_push_actions` and `event_push_summary` is
backfilled with `"main"` for all existing rows. New entries into `event_push_actions`
and `event_push_actions_staging` will get the proper thread ID.
`receipts_linearized` and `receipts_graph` also gain a `thread_id` column, which is similar,
except `NULL` is a special value meaning the receipt is "unthreaded".
See MSC3771 and MSC3773 for where this data will be useful.
Partial indices have been supported since SQLite 3.8, but Synapse
now requires >= 3.27, so we can enable support for them.
This requires rebuilding previous indices which were partial on
PostgreSQL, but not on SQLite.
* Remove incorrect migration file from `state` logical DB
The table `ex_outlier_stream` is part of the `main` logical DB; it
should not have been created in the `state` logical DB. We remove this
migration now as a tidy-up.
Note: we cannot `DROP TABLE IF EXISTS ex_outlier_stream` in a new
migration, because some (most) instances of Synapse host both of these
logical DBs on the same DB cluster.
* Changelog
When a remote user leaves the last room shared with the homeserver, we
have to mark their device list as unsubscribed, otherwise we would hold
on to a stale device list in our cache. Crucially, the device list would
remain cached even after the remote user rejoined the room, which could
lead to E2EE failures until the next change to the remote user's device
list.

Most of the time this function is heavily cached, but when that isn't
the case fetching the counts room by room slows down push delivery on

The problem with many services is that it makes it hard to find which service has the trace you want, see https://github.com/jaegertracing/jaeger-ui/issues/985
Previously, we split traces out into services based on their instance name like `matrix.org client_reader-1`, etc but there are many worker instances of the same `client_reader` so there is a lot to click through.
With this PR, all of the traces are just collected under the worker type like `client_reader`, `event_persister` 😇
Note: A Synapse worker instance name is an opaque string with the number convention only being our own thing for the `matrix.org` deployment. But seems pretty sensible to group things this way.
