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
