Follows on from @H-Shay's great work at
https://github.com/matrix-org/synapse/pull/15344 and MSC4026.
Also enables its use for MSC3881, mainly as an easy but concrete example
of how to use it.
This can help ensure that the rooms are eventually purged if the other
local users also forget them. Synapse already clears some of the room
information as part of the `_background_remove_left_rooms` background
task, but this doesn't catch `events`, `event_json`, etc.
Fixes https://github.com/element-hq/synapse/issues/17274, hopefully.
Basically, old versions of Synapse could advance streams without
persisting anything in the DB (fixed in #17229). On restart those
updates would get lost, and so the position of the stream would revert
to an older position. If this happened across an upgrade to a later
Synapse version which included #17215, then sync could get blocked
indefinitely (until the stream advanced to the position in the token).
We fix this by bounding the stream positions we'll wait for to the
maximum position of the underlying stream ID generator.

If we leave the `.so` in place it causes the tests to fail, as it gets
picked up (instead of the newly built .so) and so fails with mismatched
GLIBC errors.
Sid now defaults to python3.12, and our pinned version of cffi (1.5.1)
does not have wheels for 3.12. This installing cffi to fail as we did
not have the correct libs installed to build from source.
Fix bug where we don't get new to-device from remote if they resent a
message we've already persisted and have recorded in the DB twice.
`device_federation_inbox` table doesn't have a unique index, and so we
can race and store an entry in there twice. If we do so then
`simple_select_one_txn` will throw an error due to the query returning
more than one row. We should add an unique index, but it doesn't really
matter so lets just handle the case of multiple rows correctly for now.
Fixes up #17333, where we failed to actually send less data (the
`DISTINCT` didn't work due to `stream_id` being different).
We fix this by making it so that every device list outbound poke for a
given user ID has the same stream ID. We can't change the query to only
return e.g. max stream ID as the receivers look up the destinations to
send to by doing `SELECT WHERE stream_id = ?`
A simple change to update the docs where default values were missing.
