Turns out not all rooms are in `rooms`, so lets fetch the room list from
`current_state_events`. We move the delta file to force it to be run
again.

Fix error handling when fetching remote device keys

Add unit test for current state membership bg update

The `expire_access_token` didn't do what it sounded like it should do. What it
actually did was make Synapse enforce the 'time' caveat on macaroons used as
access tokens, but since our access token macaroons never contained such a
caveat, it was always a no-op.

(The code to add 'time' caveats was removed back in v0.18.5, in #1656)

Fix room summary when rejected events are in state

Remove some more joins on room_memberships

Fix current_state bg update to work on old SQLite

* Fix debian packages for sid being called buster.

I don't know why the sid images return buster as its codename in
`lsb_release` but it does, so lets just grab the codename from the
distro we pass into dockerfile

* Newsfile

Add ability to pass arguments to looping calls

Log when we receive a /make_* request from a different origin

Annoyingly, `current_state_events` table can include rejected events,
in which case the membership column will be null. To work around this
lets just always filter out null membership for now.

Make sure that synapse doesn't explode when a redaction redacts itself, or
there is a larger cycle.
