This adds a new admin endpoint `/_dendrite/admin/purgeRoom/{roomID}`. It
completely erases all database entries for a given room ID.
The roomserver will start by clearing all data for that room and then
will generate an output event to notify downstream components (i.e. the
sync API and federation API) to do the same.
It does not currently clear media and it is currently not implemented
for SQLite since it relies on SQL array operations right now.

The stale device lists table might contain entries for users we don't
share a room with anymore. This now asks the roomserver about left users
and removes those entries from the table.

Makes the following tests pass
```
/upgrade moves remote aliases to the new room
Local and remote users' homeservers remove a room from their public directory on upgrade
```
This optimizes history visibility checks by (mostly) avoiding database
hits.

Adds `PUT
/_matrix/client/v3/directory/list/appservice/{networkId}/{roomId}` and
`DELTE
/_matrix/client/v3/directory/list/appservice/{networkId}/{roomId}`
support, as well as the ability to filter `/publicRooms` on networkID
and including all networks.

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.
* 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
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
* Don't proactively cache event types and state keys when we don't know if the transaction has persisted yet
* Remove event type and state key caches altogether
* Only add events to `add_state_events` that haven't already been sent to the roomserver output before

* Check that we have a populated state snapshot when determining if we closed the gap
* Do the same in the query API
* Use HasState more opportunistically
* Try to avoid falling down the hole of using a trustworthy but empty state snapshot for non-create events
* Refactor missing state and make sure that we really solve the problem for the new event
* Comments
* Review comments
* Tweak that check again
* Tidy up that create check further
* Fix build hopefully

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.
