MSC2836: Threading - part one (#1589)
* Add mscs/hooks package, begin work for msc2836 * Flesh out hooks and add SQL schema * Begin implementing core msc2836 logic * Add test harness * Linting * Implement visibility checks; stub out APIs for tests * Flesh out testing * Flesh out walkThread a bit * Persist the origin_server_ts as well * Edges table instead of relationships * Add nodes table for event metadata * LEFT JOIN to extract origin_server_ts for children * Add graph walking structs * Implement walking algorithm * Add more graph walking tests * Add auto_join for local rooms * Fix create table syntax on postgres * Add relationship_room_id|servers to the unsigned section of events * Persist the parent room_id/servers in edge metadata 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
