Remove unnecessary error line (#2237)
Previously this error line would print because we were pulling out all user memberships, but now this is no longer necessary — an event state key that we don't know will no longer get passed to `SelectJoinedUsersSetForRooms` at all.

MSC2946: Spaces Summary (round 2) (#2232)
* Initial cut at fixing up MSC2946 to work with latest spec

* 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`.

* Sort child rooms

* msc2946: Make TestClientSpacesSummary pass

* msc2946: allow invited rooms to be spidered

* msc2946: support basic federation requests

* fix up go mod

Remove error when state keys are missing for user NIDs (#2213)
* 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
);
```

* Logging

Remove roomserver input deadlines (#2144)
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 (#2137)
* 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.

* Don't send invite pokes in PerformInvite

* Move event ID into logger

Fix #2027 by gracefully handling stub rooms (#2100)
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.

Fix sqlite migration issues (#1960)
* Do not store 'null' in the database for empty JSON arrays

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.

* Add state key check

db migration: fix #1844 and add additional assertions (#1889)
* 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).

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.

Implement rejected events (#1426)
* 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

Refactor roomserver/internal - split perform stuff out (#1380)

- New package `helpers` which contains helper functions used by both
  perform and query/input functions.
- Perform invite/leave have no idea how to `WriteOutputEvents` and this
  is now returned from `PerformInvite` or `PerformLeave` respectively.

Still to do:
 - RSAPI is fed into the inviter/joiner/leaver - this introduces circular
   logic so will need to be removed.
 - Put query operations in a `query` package.
 - Put input operations (and output) in an `input` package.
 - Factor out helper functions as much as possible, possibly rejigging the
   storage layer in the process.

- Requests to (un)publish rooms are sent to the roomserver via `PerformPublish`

- Requests for public rooms are handled in clientapi by:
    * Fetch all room IDs which are published using `QueryPublishedRooms` on the roomserver.
    * Apply pagination parameters to the slice.
    * Do a `QueryBulkStateContent` request to the currentstateserver to pull out
      required state event *content* (not entire events).

sytest: Make 'Inbound federation can backfill events' pass (#1051)
* sytest: Make 'Inbound federation can backfill events' pass

This breaks 'Outbound federation can backfill events' because now
we are returning the right number of events, which the previous
test was relying on.

Previously, /messages was backfilling the membership event, causing
the test to pass. Now we are no longer backfilling the membership
event due to the change in this commit, causing the test to fail.

The test should instead be returning the membership event locally
from synacpis database, but it doesn't do it fast enough, resulting
in a no-op /sync response with a next_batch=s0_0 which will never
pick up the local membership event when it rolls in. The test
does attempt to retry, but doesn't take the new next_batch=s1_0
resulting in it missing from the /messages response.

Implement backfill in the roomserver (#983)
* Initial cut for backfilling

The syncserver now asks the roomserver via QueryBackfill (which already

via gomatrixserverlib.RequestBackfill.

which servers are in the room, because we are unable to get state snapshots
from a backfilled event because that code doesn't exist yet.

    use custom http client instead of the http DefaultClient (#823)

    This commit replaces the default client from the http lib with a custom one.
    The previously used default client doesn't come with a timeout. This could cause
    unwanted locks.
    That solution chosen here creates a http client in the base component dendrite
    with a constant timeout of 30 seconds. If it should be necessary to overwrite
    this, we could include the timeout in the dendrite configuration.
    Here it would be a good idea to extend the type "Address" by a timeout and
    create an http client for each service.

    Closes #820
