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

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
