* Make _iterate_over_text easier to read by using simple data structures

* Prefer a set of tags to ignore

In my tests, it's 4x faster to check for containment in a set of this size

* Add a stack size limit to _iterate_over_text

* Continue accepting the case where there is no body element

* Use an early return instead for None

Update opentracing docs to reference the configuration manual rather than the configuation file. (#13076)

* Extend the auth rule checks for `m.room.create` events

... and move them up to the top of the function. Since the no auth_events are
allowed for m.room.create events, we may as well get the m.room.create event
checks out of the way first.

* Add a test for create events with prev_events

* Fix type error introduced accidentally by #13045

* Newsfile

When we fail to persist a federation event, we kick off a task to remove
its push actions in the background, using the current logging context.
Since we don't `await` that task, we may finish our logging context
before the task finishes. There's no reason to not `await` the task, so
let's do that.

Pull out `twitter:` meta tags when generating a preview and
use it to augment any `og:` meta tags.

Prefers Open Graph information over Twitter card information.

If no database is configured explicitly, use sqlite.

This means that you don't have to pass any variables into the image.
