* Upsert redactions in case they already exists
Occasionally, in combination with retention, redactions aren't deleted
from the database whenever they are due for deletion. The server will
eventually try to backfill the deleted events and trip over the already
existing redaction events.
Switching to an UPSERT for those events allows us to recover from there
situations. The retention code still needs fixing but that is outside of
my current comfort zone on this code base.
This is related to #8707 where the error was discussed already.

* Also purge redactions when purging events
Previously redacints where left behind leading to backfilling issues
when the server stumbled across the already existing yet to be
backfilled redactions.
This issues has been discussed in #8707.

* Make `invalidate` and `invalidate_many` do the same thing
... so that we can do either over the invalidation replication stream, and also
because they always confused me a bit.
* Kill off `invalidate_many`
* changelog
Part of #9744
Removes all redundant `# -*- coding: utf-8 -*-` lines from files, as python 3 automatically reads source code as utf-8 now.

* Populate `internal_metadata.outlier` based on `events` table
Rather than relying on `outlier` being in the `internal_metadata` column,
populate it based on the `events.outlier` column.
* Move `outlier` out of InternalMetadata._dict
Ultimately, this will allow us to stop writing it to the database. For now, we
have to grandfather it back in so as to maintain compatibility with older
versions of Synapse.
The idea here is to stop people forgetting to call `check_consistency`. Folks can still just pass in `None` to the new args in `build_sequence_generator`, but hopefully they won't.
- Update black version to the latest
- Run black auto formatting over the codebase
- Run autoformatting according to [`docs/code_style.md
`](80d6dc9783/docs/code_style.md)
- Update `code_style.md` docs around installing black to use the correct version
Not being able to serialise `frozendicts` is fragile, and it's annoying to have
to think about which serialiser you want. There's no real downside to
supporting frozendicts, so let's just have one json encoder.
There's no need for it to be in the dict as well as the events table. Instead,
we store it in a separate attribute in the EventInternalMetadata object, and
populate that on load.
This means that we can rely on it being correctly populated for any event which
has been persited to the database.
This is *not* ready for production yet. Caveats:
1. We should write some tests...
2. The stream token that we use for events can get stalled at the minimum position of all writers. This means that new events may not be processed and e.g. sent down sync streams if a writer isn't writing or is slow.
