This fixes an KeyError exception, after this PR the content
is just considered unknown.

If we see stale extremities while persisting events, and notice that
they don't change the result of state resolution, we drop them.

... and disable coverage tracking for mypy and friends.

* Use the simple dictionary in fts for the user directory

* Clarify naming

Fixes a bug that deactivated users appear in the directory when their profile information was updated.

To change profile information of deactivated users is neccesary for example you will remove displayname or avatar.
But they should not appear in directory. They are deactivated.

This is another part of my work towards fixing #8876. It moves some of the logic currently in the SAML and OIDC handlers - in particular the call to `AuthHandler.complete_sso_login` down into the `SsoHandler`.

Move it from the federation section to the server section to match
ip_range_blacklist.

This improves type hinting and should use less memory.

More preparatory refactoring of the OidcHandler tests

Remove `Request` return value from `make_request`

It used to write an empty file if you gave it a -o arg.

... so that we can test its behaviour when it raises.

Also pull it out to the top level so that I can use it from other test classes.

The tests that need this all do it already.

despite the warnings saying "don't implement get_extra_attributes", we had
implemented it, so the tests weren't doing what we thought they were.

This was never used, so let's get rid of it.

this didn't seem to be doing a lot, so remove it.

The two are equivalent, but really we want to check the HTTP result that got
returned to the channel, not the code that the Request object *intended* to
return to the channel.

* move simple_async_mock to test_utils

... so that it can be re-used

* Remove references to `SamlHandler._map_saml_response_to_user` from tests

This method is going away, so we can no longer use it as a test point. Instead,
factor out a higher-level method which takes a SAML object, and verify correct
behaviour by mocking out `AuthHandler.complete_sso_login`.

* changelog

Removes faulty assertions and fixes the logic to ensure the max
stream token is always set.

* Remove references to handler._auth_handler

(and replace them with hs.get_auth_handler)

* Factor out a utility function for building Requests

* Remove mocks of `OidcHandler._map_userinfo_to_user`

This method is going away, so mocking it out is no longer a valid approach.

Instead, we mock out lower-level methods (eg _remote_id_from_userinfo), or
simply allow the regular implementation to proceed and update the expectations
accordingly.

* Remove references to `OidcHandler._map_userinfo_to_user` from tests

This method is going away, so we can no longer use it as a test point. Instead
we build mock "callback" requests which we pass into `handle_oidc_callback`,
and verify correct behaviour by mocking out `AuthHandler.complete_sso_login`.

Spam checker modules can now provide async methods. This is implemented
in a backwards-compatible manner.

Fixes #8846.
