Before this PR, you would see a warning in the logs and the span was not exported:
```
2022-08-03 19:11:59,383 - synapse.logging.opentracing - 835 - ERROR - GET-0 - @trace may not have wrapped EventFederationWorkerStore.get_oldest_event_ids_with_depth_in_room correctly! The function is not async but returned a coroutine.
```
In state res v2, we apply two passes of iterative auth checks. The first
pass replays power events and events in their auth chains, but only
those belonging to the full conflicted set. The source code as written
suggests that we want only those belonging to the auth difference (which
is a smaller set of events).
At runtime we were doing the correct thing anyway, because the only
callsite of `_reverse_topological_power_sort` passes in the
`full_conflicted_set`. So this really is just a rename.
This adds support for the stable identifiers of MSC2285 while
continuing to support the unstable identifiers behind the configuration
flag. These will be removed in a future version.
Fix @tag_args being off-by-one (ahead)
Example:
```
argspec.args=[
'self',
'room_id'
]
args=(
<synapse.storage.databases.main.DataStore object at 0x10d0b8d00>,
'!HBehERstyQBxyJDLfR:my.synapse.server'
)
```
---
The previous logic was also flawed and we can end up in a situation like this:
```
argspec.args=['self', 'dest', 'room_id', 'limit', 'extremities']
args=(<synapse.federation.federation_client.FederationClient object at 0x7f1651c18160>, 'hs1', '!jAEHKIubyIfuLOdfpY:hs1')
```
From this source:
```py
async def backfill(
self, dest: str, room_id: str, limit: int, extremities: Collection[str]
) -> Optional[List[EventBase]]:
```
And this usage:
```py
events = await self._federation_client.backfill(
dest, room_id, limit=limit, extremities=extremities
)
```
which would previously cause this error:
```

* Adds docstrings and inline comments.

* Minor formatting changes.
* Avoid fetching `event_push_summary_stream_ordering` multiple times
in the same transactions.
Still maintains local in memory lookup optimisation, but does any external
lookup as part of the deferred that prevents duplicate lookups for the same
event at once. This makes the assumption that fetching from an external
cache is a non-zero load operation.

Previously, `_resolve_state_at_missing_prevs` returned the resolved
state before an event and a partial state flag. These were unwieldy to
carry around would only ever be used to build an event context. Build
the event context directly instead.

Synapse 1.64.0rc2 (2022-07-29)
==============================
This RC reintroduces support for `account_threepid_delegates.email`, which was removed in 1.64.0rc1. It remains deprecated and will be removed altogether in a future release. ([\#13406](https://github.com/matrix-org/synapse/issues/13406))
The `room_id` field represented the parent space for each room
and was made redundant by changes in the API shape where the
`children_state` is now nested underneath each `room`.
The room ID of each child is in the `state_key` field and is still
available.
Avoid blocking on full state in `_resolve_state_at_missing_prevs` and
return a new flag indicating whether the resolved state is partial.
Thread that flag around so that it makes it into the event context.

When registering a new account via SSO on iOS, the text field becomes pretty annoying as it autocapitalises and autocorrects your input. This PR fixes that (although I have only tested the raw HTML file on the simulator, I'm not sure how to get the complete setup available for testing in the flow).
Previously, TLS could only be used with STARTTLS.
Add a new option `force_tls`, where TLS is used from the start.
Implicit TLS is recommended over STARTLS,

See #10826 and #10786 for context as to why we had to disable pruning on
those caches.
Now that `get_users_who_share_room_with_user` is called frequently only
for presence, we just need to make calls to it less frequent and then we
can remove the various levels of caching that is going on.
When a room has the partial state flag, we may not have an accurate
`m.room.member` event for event senders in the room's current state, and
so cannot perform soft fail checks correctly. Skip the soft fail check
entirely in this case.
As an alternative, we could block until we have full state, but that
would prevent us from receiving incoming events over federation, which
is undesirable.

## New error code and status
### Before
Previously, we returned a `404` for `/thumbnail` which isn't even in the spec.
```json
{
"errcode": "M_NOT_FOUND",
"error": "Not found [b'hs1', b'tefQeZhmVxoiBfuFQUKRzJxc']"
}
```
### After
What does the spec say?
> 400: The request does not make sense to the server, or the server cannot thumbnail the content. For example, the client requested non-integer dimensions or asked for negatively-sized images.
>
> *-- https://spec.matrix.org/v1.1/client-server-api/#get_matrixmediav3thumbnailservernamemediaid*
Now with this PR, we respond with a `400` when we don't have thumbnails to serve and we explain why we might not have any thumbnails.
```json
{
"errcode": "M_UNKNOWN",
"error": "Cannot find any thumbnails for the requested media ([b'example.com', b'12345']). This might mean the media is not a supported_media_format=(image/jpeg, image/jpg, image/webp, image/gif, image/png) or that thumbnailing failed for some other reason. (Dynamic thumbnails are disabled on this server.)",
}
```

---
We still respond with a 404 in many other places. But we can iterate on those later and maybe keep some in some specific places after spec updates/clarification: https://github.com/matrix-org/matrix-spec/issues/1122
We can also iterate on the bugs where Synapse doesn't thumbnail when it should in other issues/PRs.
These columns were added back in Synapse 1.52, and have been populated for new
events since then. It's now (beyond) time to back-populate them for existing
events.
There are two fixes here:
1. A long-standing bug where we incorrectly calculated `delta_ids`; and
2. A bug introduced in #13267 where we got current state incorrect.
Some experimental prep work to enable external event caching based on #9379 & #12955. Doesn't actually move the cache at all, just lays the groundwork for async implemented caches.

* Replace `get_new_events_for_appservice` with `get_all_new_events_stream`
The functions were near identical and this brings the AS worker closer
to the way federation senders work which can allow for multiple workers
to handle AS traffic.
* Pull received TS alongside events when processing the stream
This avoids an extra query -per event- when both federation sender
and appservice pusher process events.
There is a corner in `_check_event_auth` (long known as "the weird corner") where, if we get an event with auth_events which don't match those we were expecting, we attempt to resolve the diffence between our state and the remote's with a state resolution.
This isn't specced, and there's general agreement we shouldn't be doing it.
However, it turns out that the faster-joins code was relying on it, so we need to introduce something similar (but rather simpler) for that.

* Drop support for delegating email validation
Delegating email validation to an IS is insecure (since it allows the owner of
the IS to do a password reset on your HS), and has long been deprecated. It
will now cause a config error at startup.
* Update unit test which checks for email verification
Give it an `email` config instead of a threepid delegate
* Remove unused method `requestEmailToken`
* Simplify config handling for email verification
Rather than an enum and a boolean, all we need here is a single bool, which
says whether we are or are not doing email verification.
* update docs
* changelog
* upgrade.md: fix typo
* update version number
this will be in 1.64, not 1.63
* update version number
this one too
This gets rid of another usage of get_appservice_by_req, with all the benefits, including correctly tracking the appservice IP and setting the tracing attributes correctly.
