Fix logging context warnings when losing replication connection (#10984)
Instead of triggering `__exit__` manually on the replication handler's
logging context, use it as a context manager so that there is an
`__enter__` call to balance the `__exit__`.

Fix 500 error on /messages when we accumulate more than 5 backward extremities (#11027)
Found while working on the Gitter backfill script and noticed
it only happened after we sent 7 batches, https://gitlab.com/gitterHQ/webapp/-/merge_requests/2229#note_665906390

When there are more than 5 backward extremities for a given depth,
backfill will throw an error because we sliced the extremity list
to 5 but then try to iterate over the full list. This causes
us to look for state that we never fetched and we get a `KeyError`.

Before when calling `/messages` when there are more than 5 backward extremities:
```

Resolve and share state_groups for all historical events in batch (MSC2716) (#10975)
Resolve and share `state_groups` for all historical events in batch.  This also helps for showing the appropriate avatar/displayname in Element and will work whenever `/messages` has one of the historical messages as the first message in the batch.

This does have the flaw where if you just insert a single historical event somewhere, it probably won't resolve the state correctly from `/messages` or `/context` since it will grab a non historical event above or below with resolved state which never included the historical state back then. For the same reasions, this also does not work in Element between the transition from actual messages to historical messages. In the Gitter case, this isn't really a problem since all of the historical messages are in one big lump at the beginning of the room.

For a future iteration, might be good to look at `/messages` and `/context` to additionally add the `state` for any historical messages in that batch.

---

How are the `state_groups` shared? To illustrate the `state_group` sharing, see this example:


**Before** (new `state_group` for every event 😬, very inefficient):
```
# Tests from https://github.com/matrix-org/complement/pull/206
$ COMPLEMENT_ALWAYS_PRINT_SERVER_LOGS=1 COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh TestBackfillingHistory/parallel/should_resolve_member_state_events_for_historical_events

create_new_client_event org.matrix.msc2716.batch event=$Oy_S7AWN7rJQe_MYwGPEy6RtbYklrI-tAhmfiLrCaKI state_group=14
```

**After** (all events in batch sharing `state_group=10`) (the base insertion event has `state_group=8` which matches the `prev_event` we're inserting next to):

```

Stop user directory from failing if it encounters users not in the users table. (#11053)
The following scenarios would halt the user directory updater:

- user joins room
- user leaves room
- user present in room which switches from private to public, or vice versa.

for two classes of users:

- appservice senders
- users missing from the user table.

If this happened, the user directory would be stuck, unable to make forward progress.

Exclude both cases from the user directory, so that we ignore them.

Fix inconsistent behavior of get_last_client_by_ip (#10970)
Make `get_last_client_by_ip` return the same dictionary structure
regardless of whether the data has been persisted to the database.

This change will allow slightly cleaner type hints to be applied later
on.

Fix opentracing and Prometheus metrics for replication requests (#10996)
This commit fixes two bugs to do with decorators not instrumenting
`ReplicationEndpoint`'s `send_request` correctly. There are two
decorators on `send_request`: Prometheus' `Gauge.track_inprogress()`
and Synapse's `opentracing.trace`.

`Gauge.track_inprogress()` does not have any support for async
functions when used as a decorator. Since async functions behave like
regular functions that return coroutines, only the creation of the
coroutine was covered by the metric and none of the actual body of
`send_request`.

`Gauge.track_inprogress()` returns a regular, non-async function
wrapping `send_request`, which is the source of the next bug.
The `opentracing.trace` decorator would normally handle async functions
correctly, but since the wrapped `send_request` is a non-async function,
the decorator ends up suffering from the same issue as
`Gauge.track_inprogress()`: the opentracing span only measures the
creation of the coroutine and none of the actual function body.

Using `Gauge.track_inprogress()` as a context manager instead of a
decorator resolves both bugs.

Relax ignore-missing-imports for modules that have stubs now and update mypy (#11006)
Updating mypy past version 0.9 means that third-party stubs are no-longer distributed with typeshed. See http://mypy-lang.blogspot.com/2021/06/mypy-0900-released.html for details.
We therefore pull in stub packages in setup.py

Additionally, some modules that we were previously ignoring import failures for now have stubs. So let's use them.

The rest of this change consists of fixups to make the newer mypy + stubs pass CI.

When exiting a read/write lock, callbacks on a `Deferred` are triggered
as a signal to any waiting coroutines. Any waiting coroutine that
becomes runnable is likely to follow the Synapse logging context rules
and will restore its own logging context, then either run to completion
or await another `Deferred`, resetting the logging context in the
process.

This is in the context of creating new module callbacks that modules in https://github.com/matrix-org/synapse-dinsic can use, in an effort to reconcile the spam checker API in synapse-dinsic with the one in mainline.

Note that a module callback already exists for 3pid invites (https://matrix-org.github.io/synapse/develop/modules/third_party_rules_callbacks.html#check_threepid_can_be_invited) but it doesn't check whether the sender of the invite is allowed to send it.

Fix potential leak of per-room profiles when the user dir is rebuilt. (#10981)
There are two steps to rebuilding the user directory:

1. a scan over rooms, followed by
2. a scan over local users.

The former reads avatars and display names from the `room_memberships`
table and therefore contains potentially private avatars and
display names. The latter reads from the the `profiles` table which only
contains public data; moreover it will overwrite any private profiles
that the rooms scan may have written to the user directory. This means
that the rebuild could leak private user while the rebuild was in
progress, only to later cover up the leaks once the rebuild had completed.

This change skips over local users when writing user_directory rows
when scanning rooms. Doing so means that it'll take longer for a rebuild
to make local users searchable, which is unfortunate. I think a future
PR can improve this by swapping the order of the two steps above. (And
indeed there's more to do here, e.g. copying from `profiles` without
going via Python.)

Small tidy-ups while I'm here:

* Remove duplicated code from test_initial. This was meant to be pulled into `purge_and_rebuild_user_dir`.
* Move `is_public` before updating sharing tables. No functional change; it's still before the first read of `is_public`.
* Don't bother creating a set from dict keys. Slightly nicer and makes the code simpler.

Fix logic flaw preventing tracking of MSC2716 events in existing room versions (#10962)
We correctly allowed using the MSC2716 batch endpoint for
the room creator in existing room versions but accidentally didn't track
the events because of a logic flaw.

This prevented you from connecting subsequent chunks together because it would
throw the unknown batch ID error.

We only want to process MSC2716 events when:

 - The room version supports MSC2716
 - Any room where the homeserver has the `msc2716_enabled` experimental feature enabled and the event is from the room creator

Consistently exclude from user_directory (#10960)
* Introduce `should_include_local_users_in_dir`

We exclude three kinds of local users from the user_directory tables. At
present we don't consistently exclude all three in the same places. This
commit introduces a new function to gather those exclusion conditions
together. Because we have to handle local and remote users in different
ways, I've made that function only consider the case of remote users.
It's the caller's responsibility to make the local versus remote
distinction clear and correct.

A test fixup is required. The test now hits a path which makes db
queries against the users table. The expected rows were missing, because
we were using a dummy user that hadn't actually been registered.

We also add new test cases to covert the exclusion logic.

----

By my reading this makes these changes:

* When an app service user registers or changes their profile, they will
  _not_ be added to the user directory. (Previously only support and
  deactivated users were excluded). This is consistent with the logic that
  rebuilds the user directory. See also [the discussion
  here](https://github.com/matrix-org/synapse/pull/10914#discussion_r716859548).
* When rebuilding the directory, exclude support and disabled users from
  room sharing tables. Previously only appservice users were excluded.
* Exclude all three categories of local users when rebuilding the
  directory. Previously `_populate_user_directory_process_users` didn't do
  any exclusion.

Split event_auth.check into two parts (#10940)
Broadly, the existing `event_auth.check` function has two parts:
 * a validation section: checks that the event isn't too big, that it has the rught signatures, etc. 
   This bit is independent of the rest of the state in the room, and so need only be done once 
   for each event.
 * an auth section: ensures that the event is allowed, given the rest of the state in the room.
   This gets done multiple times, against various sets of room state, because it forms part of
   the state res algorithm.

Currently, this is implemented with `do_sig_check` and `do_size_check` parameters, but I think
that makes everything hard to follow. Instead, we split the function in two and call each part
separately where it is needed.

Inline _check_event_auth for outliers (#10926)
* Inline `_check_event_auth` for outliers

When we are persisting an outlier, most of `_check_event_auth` is redundant:

 * `_update_auth_events_and_context_for_auth` does nothing, because the
   `input_auth_events` are (now) exactly the event's auth_events,
   which means that `missing_auth` is empty.

 * we don't care about soft-fail, kicking guest users or `send_on_behalf_of`
   for outliers

... so the only thing that matters is the auth itself, so let's just do that.

* `_auth_and_persist_fetched_events_inner`: de-async `prep`

`prep` no longer calls any `async` methods, so let's make it synchronous.

* Simplify `_check_event_auth`

We no longer need to support outliers here, which makes things rather simpler.

* changelog

* lint

Encode JSON responses on a thread in C, mk2 (#10905)
Currently we use `JsonEncoder.iterencode` to write JSON responses, which ensures that we don't block the main reactor thread when encoding huge objects. The downside to this is that `iterencode` falls back to using a pure Python encoder that is *much* less efficient and can easily burn a lot of CPU for huge responses. To fix this, while still ensuring we don't block the reactor loop, we encode the JSON on a threadpool using the standard `JsonEncoder.encode` functions, which is backed by a C library.

Doing so, however, requires `respond_with_json` to have access to the reactor, which it previously didn't. There are two ways of doing this:

1. threading through the reactor object, which is a bit fiddly as e.g. `DirectServeJsonResource` doesn't currently take a reactor, but is exposed to modules and so is a PITA to change; or
2. expose the reactor in `SynapseRequest`, which requires updating a bunch of servlet types.

I went with the latter as that is just a mechanical change, and I think makes sense as a request already has a reactor associated with it (via its http channel).

Add a spamchecker callback to allow or deny room creation based on invites (#10898)
This is in the context of creating new module callbacks that modules in https://github.com/matrix-org/synapse-dinsic can use, in an effort to reconcile the spam checker API in synapse-dinsic with the one in mainline.

This adds a callback that's fairly similar to user_may_create_room except it also allows processing based on the invites sent at room creation.

Update postgresql testing script (#10906)
- Use sytest:bionic. Sytest:latest is two years old (do we want
  CI to push out latest at all?) and comes with Python 3.5, which we
  explictly no longer support. The script now runs under PostgreSQL 10
  as a result.
- Advertise script in the docs
- Move pg testing script to scripts-dev directory
- Write to host as the script's exector, not root

A few changes to make it speedier to re-run the tests:

- Create blank DB in the container, not the script, so we don't have to
  `initdb` each time
- Use a named volume to persist the tox environment, so we don't have to
  fetch and install a bunch of packages from PyPI each time

Factor out common code for persisting fetched auth events (#10896)
* Factor more stuff out of `_get_events_and_persist`

It turns out that the event-sorting algorithm in `_get_events_and_persist` is
also useful in other circumstances. Here we move the current
`_auth_and_persist_fetched_events` to `_auth_and_persist_fetched_events_inner`,
and then factor the sorting part out to `_auth_and_persist_fetched_events`.

* `_get_remote_auth_chain_for_event`: remove redundant `outlier` assignment

`get_event_auth` returns events with the outlier flag already set, so this is
redundant (though we need to update a test where `get_event_auth` is mocked).

* `_get_remote_auth_chain_for_event`: move existing-event tests earlier

Move a couple of tests outside the loop. This is a bit inefficient for now, but
a future commit will make it better. It should be functionally identical.

* `_get_remote_auth_chain_for_event`: use `_auth_and_persist_fetched_events`

We can use the same codepath for persisting the events fetched as part of an
auth chain as for those fetched individually by `_get_events_and_persist` for
building the state at a backwards extremity.

* `_get_remote_auth_chain_for_event`: use a dict for efficiency

`_auth_and_persist_fetched_events` sorts the events itself, so we no longer
need to care about maintaining the ordering from `get_event_auth` (and no
longer need to sort by depth in `get_event_auth`).

That means that we can use a map, making it easier to filter out events we
already have, etc.

* `_auth_and_persist_fetched_events`: improve docstring

Fix AuthBlocking check when requester is appservice (#10881)
If the MAU count had been reached, Synapse incorrectly blocked appservice users even though they've been explicitly configured not to be tracked (the default). This was due to bypassing the relevant if as it was chained behind another earlier hit if as an elif.

This makes the user_directory.py in storage pass most of mypy's

The handlers directory has already been mypyed.

Factor out _get_remote_auth_chain_for_event from _update_auth_events_and_context_for_auth (#10884)
* Reload auth events from db after fetching and persisting

In `_update_auth_events_and_context_for_auth`, when we fetch the remote auth
tree and persist the returned events: load the missing events from the database
rather than using the copies we got from the remote server.

This is mostly in preparation for additional refactors, but does have an
advantage in that if we later get around to checking the rejected status, we'll
be able to make use of it.

Fix /initialSync error due to unhashable RoomStreamToken (#10827)
The deprecated /initialSync endpoint maintains a cache of responses,
using parameter values as part of the cache key. When a `from` or `to`
parameter is specified, it gets converted into a `StreamToken`, which
contains a `RoomStreamToken` and forms part of the cache key.
`RoomStreamToken`s need to be made hashable for this to work.

Include outlier status in str(event) for V2/V3 events (#10879)
I meant to do this before, in #10591, but because I'm stupid I forgot to do it
for V2 and V3 events.

I've factored the common code out to `EventBase` to save us having two copies
of it.

This means that for `FrozenEvent` we replace `self.get("event_id", None)` with
`self.event_id`, which I think is safe. `get()` is an alias for
`self._dict.get()`, whereas `event_id()` is an `@property` method which looks
up `self._event_id`, which is populated during construction from the same
dict. We don't seem to rely on the fallback, because if the `event_id` key is
absent from the dict then construction of the `EventBase` object will
fail.

Long story short, the only way this could change behaviour is if
`event_dict["event_id"]` is changed *after* the `EventBase` object is
constructed without updating the `_event_id` field, or vice versa - either of
which would be very problematic anyway and the behavior of `str(event)` is the
least of our worries.
