Cleanup stale device lists for users we don't share a room with anymore (#2857)
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.

hits.
Possibly solves https://github.com/matrix-org/dendrite/issues/2777

Fix /get_missing_events for rooms with joined/invited history_visibility (#2787)
Sytest was using a wrong `history_visibility` for `invited`
(https://github.com/matrix-org/sytest/pull/1303), so `invited` was
passing for the wrong reason (-> defaulted to `shared`, as `invite`
wasn't understood).
This change now handles missing events like Synapse, if a server isn't
allowed to see the event, it gets a redacted version of it, making the
`get_missing_events` tests pass.

Optimise QuerySharedUsers so that we can only work on local users (#2766)

Check unique constraint errors when manually inserting migrations (#2712)
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.

Change detection of already executed migrations (#2665)
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`.

* db migration: fix #1844 and add additional assertions

- Migration scripts will now check to see if there are any unconverted
  snapshot IDs and fail the migration if there are any. This should
  prevent people from getting a corrupt database in the event the root
  cause is still unknown.
- Add an ORDER BY clause when doing batch queries in the postgres
  migration. LIMIT and OFFSET without ORDER BY are undefined and must
  not be relied upon to produce a deterministic ordering (e.g row order).
