I was sad that I couldn't do better for
`_curr_state_delta_stream_cache`. At least it's explicitly called out in
a comment with #TODO.

This was only checking the __init__ files in modules instead of
all files in a module, which don't pass yet.

* Prefer `HTTPStatus` over plain `int`

This is an Opinion that no-one has seemed to object to yet.

* `--disallow-untyped-defs` for `tests.rest.client.test_directory`
* Improve synapse's annotations for deleting aliases
* Test case for deleting a room alias
* Changelog

* change display names/avatar URLS to None if they contain null bytes

* add changelog

* add POC test, requested changes

* add a saner test and remove old one

* update test to verify that display name has been changed to None

* make test less fragile

* Make DataStore inherit from EventForwardExtremitiesStore before CacheInvalidationWorkerStore

the former implicitly inherits from the latter, so they should be
ordered like this when used.

* Annotate HomeserverTestCase.servlets
* Correct annotation of federation_auth_origin
* Use AnyStr custom_headers instead of a Union

This allows (str, str) and (bytes, bytes).
This disallows (str, bytes) and (bytes, str)

* DomainSpecificString.SIGIL is a ClassVar

I'm not sure why this was excluded---it seemed to be passing for me. But
it's easy enough to fixup.

as of #11012, these parameters are unused.

Context: https://github.com/matrix-org/synapse/pull/11114/files#r741643968

This was due to a conflict between #11282, which changed
mypy configuration, and #11228, a normal change.

Adds experimental support for `relation_types` and `relation_senders`
fields for filters.

When fetching remote devices for the first time, we did not correctly include the cross signing keys in the returned results.

c.f. #11159

Co-authored-by: reivilibre <olivier@librepush.net>

`get_insertion_event_by_batch_id` -> `get_insertion_event_id_by_batch_id`

Split out from https://github.com/matrix-org/synapse/pull/11114

Fixes #11259

We might as well use a default value for `public_baseurl` based on
`server_name` - in many cases, it will be correct.

* Make lock better handle process being killed

If the process gets killed and restarted (so that it didn't have a
chance to drop its locks gracefully) then there may still be locks in
the DB that are for the same instance that haven't yet timed out but are
safe to delete.

We handle this case by a) checking if the current instance already has
taken out the lock, and b) if not then ignoring locks that are for the
same instance.

* Periodically check for old staged events

This is to protect against other instances dying and their locks timing
out.
