bbb75ff6ee Exclude rejected state events when calculating state at backwards extrems (#6527)
This fixes a weird bug where, if you were determined enough, you could end up with a rejected event forming part of the state at a backwards-extremity. Authing that backwards extrem would then lead to us trying to pull the rejected event from the db (with allow_rejected=False), which would fail with a 404.

ff773ff724 Persist auth/state events at backwards extremities when we fetch them (#6526)
The main point here is to make sure that the state returned by _get_state_in_room has been authed before we try to use it as state in the room.

6577f2d887 Sanity-check room ids in event auth (#6530)

35bbe4ca79 Check the room_id of events when fetching room state/auth (#6524)
When we request the state/auth_events to populate a backwards extremity (on
backfill or in the case of missing events in a transaction push), we should
check that the returned events are in the right room rather than blindly using
them in the room state or auth chain.

Given that _get_events_from_store_or_dest takes a room_id, it seems clear that
it should be sanity-checking the room_id of the requested events, so let's do
it there.

20d5ba16e6 Add include_event_in_state to _get_state_for_room (#6521)
Make it return the state *after* the requested event, rather than the one
before it. This is a bit easier and requires fewer calls to
get_events_from_store_or_dest.

4c7b1bb6cc Refactor get_events_from_store_or_dest to return a dict (#6501)
There was a bunch of unnecessary conversion back and forth between dict and
list going on here. We can simplify a bunch of the code.

Brendan Abolivier
487f1bb49d
Use the filtered version of an event when responding to /context requests for that event
Sometimes the filtering function can return a pruned version of an event (on top of either the event itself or an empty list), if it thinks the user should be able to see that there's an event there but not the content of that event. Therefore, the previous logic of 'if filtered is empty then we can use the event we retrieved from the database' is flawed, and we should use the event returned by the filtering function.

Fix inaccurate per-block metrics (#6491)
`Measure` incorrectly assumed that it was the only thing being done by the parent `LoggingContext`. For instance, during a "renew group attestations" operation, hundreds of `outbound_request` calls could take place in parallel, all using the same `LoggingContext`. This would mean that any resources used during *any* of those calls would be reported against *all* of them, producing wildly inaccurate results.

Instead, we now give each `Measure` block its own `LoggingContext` (using the parent `LoggingContext` mechanism to ensure that the log lines look correct and that the metrics are ultimately propogated to the top level for reporting against requests/backgrond tasks).

8ad8bcbed0 Pull out room_invite_state_types config option once.
Pulling things out of config is currently surprisingly expensive.

Remove fallback for missing /federation/v1/state_ids API (#6488)
This API was added way back in 0.17.0; the code here is annoying to maintain
and entirely redundant.
