c132c8e505 Handle the case of get_missing_events failing
Currently if a call to `/get_missing_events` fails we log an exception
and stop processing the top level event we received over federation.
Instead let's try and handle it sensibly given it is a somewhat expected
failure mode.

057715aaa2 Allowing specifying IS to use in unbind API.
By default the homeserver will use the identity server used during the
binding of the 3PID to unbind the 3PID. However, we need to allow
clients to explicitly ask the homeserver to unbind via a particular
identity server, for the case where the 3PID was bound out of band from
the homeserver.

Implements MSC915.

9fbbc3d9e5 For unbind poke IS used during binding of 3PID
This changes the behaviour from using the server specified trusted
identity server to using the IS that used during the binding of the
3PID, if known.

This is the behaviour specified by MSC1915.

197fae1639 Use event streams to calculate presence
Primarily this fixes a bug in the handling of remote users joining a
room where the server sent out the presence for all local users in the
room to all servers in the room.

We also change to using the state delta stream, rather than the
distributor, as it will make it easier to split processing out of the
master process (as well as being more flexible).

Finally, when sending presence states to newly joined servers we filter
out old presence states to reduce the number sent. Initially we filter
out states that are offline and have a last active more than a week ago,
though this can be changed down the line.

Fixes #3962

74c46d81fa Only require consent for events with an associated request
There are a number of instances where a server or admin may puppet a
user to join/leave rooms, which we don't want to fail if the user has
not consented to the privacy policy. We fix this by adding a check to
test if the requester has an associated access_token, which is used as a
proxy to answer the question of whether the action is being done on
behalf of a real request from the user.

d42b41544a When re-syncing device lists reset the state
We keep track of what stream IDs we've seen so that we know what updates
we've handled or missed. If we re-sync we don't know if the updates
we've seen are included in the re-sync (there may be a race), so we
should reset the seen updates.

32e54b472a Fix kicking guest users in worker mode
When guest_access changes from allowed to forbidden all local guest
users should be kicked from the room. This did not happen when
revocation was received from federation on a worker.

Presumably broken in #4141

eb2b8523ae Split out registration to worker
This allows registration to be handled by a worker, though the actual
write to the database still happens on master.

Note: due to the in-memory session map all registration requests must be
handled by the same worker.

ed8c5e4cda Fix remote invite rejections not comming down sync
This was broken in PR #4405, commit 886e5ac, where we changed remote
rejections to be outliers.

The fix is to explicitly add the leave event in when we know its an out
of band invite. We can't always add the event as if the server is/was in
the room there might be more events to send down the sync than just the
leave.

7615a8ced1 ACME config cleanups (#4525)
* Handle listening for ACME requests on IPv6 addresses

the weird url-but-not-actually-a-url-string doesn't handle IPv6 addresses
without extra quoting. Building a string which you are about to parse again
seems like a weird choice. Let's just use listenTCP, which is consistent with
what we do elsewhere.

* Clean up the default ACME config

make it look a bit more consistent with everything else, and tweak the defaults
to listen on port 80.
