Remove BaseDendrite (#3023)
Removes `BaseDendrite` to, hopefully, make testing and composing of
components easier in the future.

Preparations for removing BaseDendrite (#3016)
Preparations to actually remove/replace `BaseDendrite`.
Quite a few changes:
- SyncAPI accepts an `fulltext.Indexer` interface (fulltext is removed
from `BaseDendrite`)
- Caches are removed from `BaseDendrite`
- Introduces a `Router` struct (likely to change)
  - also fixes #2903
- Introduces a `sqlutil.ConnectionManager`, which should remove
`base.DatabaseConnection` later on
- probably more

Unset RoomServerEvent, since we can't be sure that Set actually updates the cached entry (#3002)
This should deflake UTs and be more correct in terms of getting
`Events`.
`Events` tries to fetch the event from the cache first and may get an
unredacted event from it, while it should already be redacted.

Make redaction check easier to read (#2995)
We need to check the redaction PL in Dendrite, if we do it in GMSL, we
end up not sending the event to the output stream because it will be
rejected.

Refactor StoreEvent, add MaybeRedactEvent, create an EventDatabase (#2989)
This PR changes the following:
- `StoreEvent` now only stores an event (and possibly prev event),
instead of also doing redactions
- Adds a `MaybeRedactEvent` (pulled out from `StoreEvent`), which should
be called after storing events
- a few other things

Refactor StoreEvent and create a new RoomDatabase interface (#2985)
This PR changes a few things:
- It pulls out the creation of several NIDs from the `StoreEvent`
function to make the functions more reusable
- Uses more caching when using those NIDs to avoid DB round trips

Optimize /sync and history visibility (#2961)
Should fix the following issues or make a lot less worse when using
Postgres:

The main issue behind #2911: The client gives up after a certain time,
causing a cascade of context errors, because the response couldn't be
built up fast enough. This mostly happens on accounts with many rooms,
due to the inefficient way we're getting recent events and current state

For #2777: The queries for getting the membership events for history
visibility were being executed for each room (I think 185?), resulting
in a whooping 2k queries for membership events. (Getting the
statesnapshot -> block nids -> actual wanted membership event)

Both should now be better by:
- Using a LATERAL join to get all recent events for all joined rooms in
one go (TODO: maybe do the same for room summary and current state etc)
- If we're lazy loading on initial syncs, we're now not getting the
whole current state, just to drop the majority of it because we're lazy
loading members - we add a filter to exclude membership events on the
first call to `CurrentState`.
- Using an optimized query to get the membership events needed to
calculate history visibility

Roomserver published pkey migration (#2960)
Adds a missed migration to update the primary key on the
roomserver_published table in postgres.

Add /_dendrite/admin/purgeRoom/{roomID} (#2662)
This adds a new admin endpoint `/_dendrite/admin/purgeRoom/{roomID}`. It
completely erases all database entries for a given room ID.

The roomserver will start by clearing all data for that room and then
will generate an output event to notify downstream components (i.e. the
sync API and federation API) to do the same.

It does not currently clear media and it is currently not implemented
for SQLite since it relies on SQL array operations right now.

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

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.

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`.
