Includes an abstract base class which both the FederationSender
and the FederationRemoteSendQueue must implement.

I've reiterated the advice about using `oidc` to migrate, since I've seen a few
people caught by this.

I've also removed a couple of the examples as they are duplicating the OIDC
documentation, and I think they might be leading people astray.

If you have the wrong version of `cryptography` installed, synapse suggests:

```
To install run:
    pip install --upgrade --force 'cryptography>=3.4.7;python_version>='3.6''
```

However, the use of ' inside '...' doesn't work, so when you run this, you get
an error.

Make pip install faster in Docker build for [Complement](https://github.com/matrix-org/complement) testing.

If files have changed in a `COPY` command, Docker will invalidate all of the layers below. So I changed the order of operations to install all dependencies before we `COPY synapse /synapse/synapse/`. This allows Docker to use our cached layer of dependencies even when we change the source of Synapse and speed up builds dramatically! `53.5s` -> `3.7s` builds 

As an alternative, I did try using BuildKit caches but this still took 30 seconds overall on that step. 15 seconds to gather the dependencies from the cache and another 15 seconds to `Installing collected packages`.

Fix https://github.com/matrix-org/synapse/issues/9364

This warning is somewhat confusing to users, so let's suppress it

Running `dmypy run` will do a `mypy` check while spinning up a daemon
that makes rerunning `dmypy run` a lot faster.

`dmypy` doesn't support `follow_imports = silent` and has
`local_partial_types` enabled, so this PR enables those options and
fixes the issues that were newly raised. Note that `local_partial_types`
will be enabled by default in upcoming mypy releases.

On NixOS, `bash` isn't under `/bin/bash` but rather in some directory in `$PATH`. Locally, I've been patching those scripts to make them work.

`/usr/bin/env` seems to be the only [portable way](https://unix.stackexchange.com/questions/29608/why-is-it-better-to-use-usr-bin-env-name-instead-of-path-to-name-as-my

) to use binaries from the PATH as interpreters.

Make it clearer in the source install step that the platform specific
prerequisites must be installed first.

Split off from https://github.com/matrix-org/synapse/pull/9491

Adds a storage method for getting the current presence of all local users, optionally excluding those that are offline. This will be used by the code in #9491 when a PresenceRouter module informs Synapse that a given user should have `"ALL"` user presence updates routed to them. Specifically, it is used here: https://github.com/matrix-org/synapse/blob/b588f16e391d664b11f43257eabf70663f0c6d59/synapse/handlers/presence.py#L1131-L1133

Note that there is a `get_all_presence_updates` function just above. That function is intended to walk up the table through stream IDs, and is primarily used by the presence replication stream. I could possibly make use of it in the PresenceRouter-related code, but it would be a bit of a bodge.

Broke in #9640

When we hit an unknown room in the space tree, see if there are other servers that we might be able to poll to get the data.

Fixes: #9447

This fixes an error ("Cannot determine consistent method resolution order (MRO)")
when running mypy with a cache.

It's legitimate behaviour to try and join a bunch of rooms at once.

Builds on the work done in #9643 to add a federation API for space summaries.

There's a bit of refactoring of the existing client-server code first, to avoid too much duplication.

Addresses https://github.com/matrix-org/synapse-dinsic/issues/70

This PR causes `ProxyAgent` to attempt to extract credentials from an `HTTPS_PROXY` env var. If credentials are found, a `Proxy-Authorization` header ([details](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Proxy-Authorization)) is sent to the proxy server to authenticate against it. The headers are *not* passed to the remote server.

Also added some type hints.
