This is what the MSC (now) requires. Fixes https://github.com/matrix-org/synapse/issues/10310.

The release script used to incorrectly write `New synapse release 1.57.0~rc1.`
instead of `New synapse release 1.57.0rc1.`

* Fix a link in `README.rst`

* newsfile

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.

* Fix grammatical error in error message

* changelog

This is an attempt to reduce the rebuild time. In short, we reduce the amount
of stuff that the dockerfile installs, so as to give a faster startup.

* Background workers aren't experimental anymore

* Newsfile

* Stream writers aren't experimental either

... with a bit more verbosity.

Broke in #12365

* 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.

Discovered after much in-depth investigation in #12281.

Closes: #12281
Closes: #3305
