Try to avoid an OOM by checking fewer extremities.
Generally this is a big rewrite of _maybe_backfill, to try and fix some of the TODOs and other problems in it. It's best reviewed commit-by-commit.
Multiple calls to `EventsWorkerStore._get_events_from_cache_or_db` can
reuse the same database fetch, which is initiated by the first call.
Ensure that cancelling the first call doesn't cancel the other calls
sharing the same database fetch.

This will mainly be useful when dealing with module callbacks, which are
all typed as returning `Awaitable`s instead of coroutines or
`Deferred`s.

When we join a room via the faster-joins mechanism, we end up with "partial
state" at some points on the event DAG. Many parts of the codebase need to
wait for the full state to load. So, we implement a mechanism to keep track of
which events have partial state, and wait for them to be fully-populated.
MSC2314 has now been closed, so we're backing out its implementation, which
originally happened in #6176.
Unfortunately it's not a direct revert, as that PR mixed in a bunch of
unrelated changes to tests etc.
* Use `poetry` to build venv in debian packages

* Changelog
* Only pull in from requirements.txt
Addresses the same problem as #12439.
* Include `test` and `all` extras
`poetry export` helpfully silently ignores an unknown extra
Haven't seen this before because it's the only place we export `all` and
`test`. I could have __sworm__ that the syntax `--extra "all test"`
worked for `poetry install`...
* Clean up requirements file on subsequence builds
* Fix shell syntax

When we run a worker-mode synapse under docker, everything gets logged to stdout. Currently, output from the workers is tacked with a worker name, for example:
```
2022-04-13 15:27:56,810 - worker:frontend_proxy1 - synapse.util.caches.lrucache - 154 - INFO - LruCache._expire_old_entries-0 - Dropped 0 items from caches
```
- note `worker:frontend_proxy1`. No such tag is applied to log lines from the master, which makes somewhat confusing reading.
To fix this, we generate a dedicated log config file for the master in the same way that we do for the workers, and use that.
In trying to use the MSC3026 busy presence status, the user's status
would be set back to 'online' next time they synced. This change makes
it so that syncing does not affect a user's presence status if it
is currently set to 'busy': it must be removed through the presence
API.
The MSC defers to implementations on the behaviour of busy presence,
so this ought to remain compatible with the MSC.
* Run "main" trial tests under poetry
Olddeps and twisted trunk tests are handled in separate PRs.
The PyPy config is a best-effort only; it's completely untested.
Pulled out from #12337.
* Changelog
This was missed when initially stabilising room version 8 and was
left in as a compatibility shim. Most homeservers have upgraded
to a version which expects the proper field name, and the failure
mode is reasonable (a user on an older server may have to attempt
joining the room twice with an obscure error message the first time).
We work through all the events with partial state, updating the state at each
of them. Once it's done, we recalculate the state for the whole room, and then
mark the room as having complete state.
