* bugfix: send response back correctly
* Initial working version of MSC2946
* msc2946: handle suggested_only; remove custom database
As the MSC doesn't require reverse lookups, we can just pull
the room state and inspect via the roomserver database. To
handle this, expand QueryCurrentState to support wildcards.
Use all this and handle `?suggested_only`.

* Update to matrix-org/gomatrixserverlib#293
* `Events` no longer returns an error, other tweaks
* Make sure `Events` is sorted for `parsedRespState` too
* Remove error when state keys are missing for user NIDs
There is still an actual bug here somewhere in the membership updater, but this check does more harm than good, since it means that the key consumers don't actually distribute updates to *anyone*. It's better just to deal with this silently for now.
To find these broken rows:
```
SELECT * FROM roomserver_membership AS m WHERE NOT EXISTS (
SELECT event_state_key_nid FROM roomserver_event_state_keys AS s
WHERE m.sender_nid = s.event_state_key_nid
);
```

It isn't really clear that the deadlines actually help in any way. Currently we can use up our 2 minutes doing something, run out of context time and then return an error which causes the transaction to rollback and forgetting everything we've done. If the message came to us from NATS then we probably will end up retrying just to be in the same situation. We'd be really a lot better if we just spent the time reconciling the problem in the first place, and then we're much less likely to need to fetch those missing auth or prev events in the future.
Also includes matrix-org/gomatrixserverlib#287 so we don't wait so long for servers that are obviously dead.

* PerformInvite: bugfix and rejig control flow
Local clients would not be notified of invites to rooms
Dendrite had already joined in all cases due to not returning
an `api.OutputNewInviteEvent` for local invites. We now do this.
This was an easy mistake to make due to the control flow of the
function which doesn't handle the happy case at the end of the
function and instead forks the function depending on if the
invite was via federation or not. This has now been changed to
handle the federated invite as if it were an error (in that we
check it, do it and bail out) rather than outstay our welcome.
This ends up with the local invite being the happy case, which
now both sends an `InputRoomEvent` to the roomserver _and_ a
`api.OutputNewInviteEvent` is returned.

The server ACL code on startup will grab all known rooms from
the rooms_table and then call `GetStateEvent` with each found
room ID to find the server ACL event. This can fail for stub
rooms, which will be present in the rooms table. Previously
this would result in an error being returned and the server
failing to start (!). Now we just return no event for stub
rooms.

This can cause issues, though it should be noted that the majority
of the time this will marshal/unmarshal just fine, see
https://play.golang.org/p/Doe2NZUgv7Q
* bugfix: sqlite migration should handle create events as having no 'before' snapshot
The state snapshot for any given event in the roomserver represents the state _before_
the event. For the create event, this is nothing, so the state snapshot nid should be 0.
In some cases this wasn't happening, resulting in a nice mix of possible options including:
- A state snapshot without any state blocks `[]` or `null`.
- A state snapshot with a single state block with a single event, the create event, causing
a circular loop. This is incorrect as it represents the state before the event, not after.

* bugfix: order the state blocks so recreating state snapshots works correctly
* db migration: fix#1844 and add additional assertions
- Migration scripts will now check to see if there are any unconverted
snapshot IDs and fail the migration if there are any. This should
prevent people from getting a corrupt database in the event the root
cause is still unknown.
- Add an ORDER BY clause when doing batch queries in the postgres
migration. LIMIT and OFFSET without ORDER BY are undefined and must
not be relied upon to produce a deterministic ordering (e.g row order).

* Add relationship_room_id|servers to the unsigned section of events

Other events cannot assert the true room_id/servers for the
parent event, only make claims to them, hence why this is
edge metadata.
* guts to pass through room_id/servers
* Refactor msc2836 to allow handling from federation
* Add JoinedVia to PerformJoin responses
* Fix tests; review comments
The previous implementation was only checking if room history was
"shared", which it wasn't for rooms where a user was invited, or world
readable rooms.
This implementation leverages the IsServerAllowed method, which already
implements the complete verification algorithm.

* Adjust backfill to send backward extremity with state before other backfilled events, include prev_events with no state amongst missing events
* Not finished refactor
* Fix test
* Remove isInboundTxn
* Remove debug logging
We expect to have missing events as we walk back in the DAG over federation
as we didn't always create the room. When checking if the server is allowed
to see those events, just give up and stop rather than fail the request.
* Rename serverkeyapi to signingkeyserver
We use "api" for public facing stuff and "server" for internal stuff.
As the server key API is internal only, we call it 'signing key server',
which also clarifies the type of key (as opposed to TLS keys, E2E keys, etc)

* WIP Event rejection
* Still send back errors for rejected events
Instead, discard them at the federationapi /send layer rather than
re-implementing checks at the clientapi/PerformJoin layer.
* Implement rejected events
Critically, rejected events CAN cause state resolution to happen
as it can merge forks in the DAG. This is fine, _provided_ we
do not add the rejected event when performing state resolution,
which is what this PR does. It also fixes the error handling
when NotAllowed happens, as we were checking too early and needlessly
handling NotAllowed in more than one place.
* Update test to match reality
* Modify InputRoomEvents to no longer return an error
Errors do not serialise across HTTP boundaries in polylith mode,
so instead set fields on the InputRoomEventsResponse. Add `Err()`
function to make the API shape basically the same.
* Remove redundant returns; linting
* Update blacklist
* SendEventWithState events as new
* Use cumulative state IDs for final event
* Error wrapping in calculateAndSetState
