This should hopefully fix an entire class of problems where components
downstream from the roomserver (i.e. the sync API) could just lose a
whole bunch of state after a rewrite operation like a federated join.
The root of the bug is that we set `RewritesState` in the output event
which instructs downstream components to purge their copy of any room
state, but then didn't send the entire state snapshot in
`adds_state_event_ids` so the downstream state ends up being incomplete
as a result.
Previously `LoadMembershipAtEvent` would fail if the state before one of
the events was not known, i.e. because it was an outlier. This modifies
it so that it gracefully handles not knowing the state and returns no
memberships instead, so that history visibility doesn't freak out and
kill `/sync` requests dead.
This should avoid unnecessary logging on startup if the migration (were
we need `InsertMigration`) was already executed.
This now checks for "unique constraint errors" for SQLite and Postgres
and fails the startup process if the migration couldn't be manually
inserted for some other reason.
This changes the detection of already executed migrations for the
roomserver state block and keychange refactor. It now uses schema tables
provided by the database engine to check if the column was already
removed. We now also store the migration in the migrations table.
This should stop e.g. Postgres from logging errors like `ERROR: column
"event_nid" does not exist at character 8`.

* Unbreak tests
* ALL THE LOGS
* Fix a race condition which could cause events to not be sent to servers
If a new room event which rewrites state arrives, we remove all joined hosts
then re-calculate them. This wasn't done in a transaction so for a brief period
we would have no joined hosts. During this interim, key change events which arrive
would not be sent to destination servers. This would sporadically fail on sytest.

Check that we got an event from the database
* Update to get correct required events
* Add flakey test to blacklist
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
