Move every db.Prepare to sqlutil.Statementlist, remove trace driver (#3026)
Doesn't buy us much, but makes everything a bit more consistent.

Also removes the SQL trace driver, as it is unused and the output is

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

Add tests for UpdateRelations (#2999)
This also fixes an issue regarding updates to relations for invalid
events, which could result in us retrying said event over and over
again, if we fail to unmarshal the event to
`gomatrixserverlib.RelationContent`, this was discovered by

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

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.

/sync performance optimizations (#2927)
Since #2849 there is no limit for the current state we fetch to
calculate history visibility. In large rooms this can cause us to fetch
thousands of membership events we don't really care about.
This now only gets the state event types and senders in our timeline,
which should significantly reduce the amount of events we fetch from the
database.

Also removes `MaxTopologicalPosition`, as it is an unnecessary DB call,
given we use the result in `topological_position < $1` calls.

Don't limit "state" (#2849)
This is apparently some incorrect behaviour that we built as a result of
a spec bug (matrix-org/matrix-spec#1314) where we were applying a filter
to the `"state"` section of the `/sync` response incorrectly. The client
then has no way to know that the state was limited.

This PR removes the state limiting, which probably also helps #2842.

Fix fragility of selectEventsWithEventIDsSQL queries (#2757)
This fixes a temporary workaround with the `selectEventsWithEventIDsSQL`
queries where fields need to be artificially added to the queries so the
row results match the format of the `syncapi_output_room_events` table.
I made similar functions that accept row results from the
`syncapi_current_room_state` table and convert them into StreamEvents
without the fields that are specific to output room events.

There is also a unit test in the first commit to ensure the resulting
behavior doesn't change from the modified queries and functions.

Fixes #601.

Improve selectRoomIDsWithAnyMembershipSQL performance (#2738)
Recently I have observed that dendrite spends a lot of time (~390s) in
`selectRoomIDsWithAnyMembershipSQL` query

```

```

Explain analyze showed correct usage of `syncapi_room_state_unique`
index:

```
dendrite_syncapi=#

 Execution Time: 2.990 ms
(8 rows)
```

Multi-column indexes in Postgres shall perform well for leftmost
columns, but I gave it a try and created
`syncapi_current_room_state_type_state_key_idx` index. I could observe
significant performance improvement. Execution time dropped from 2.9 ms
to 0.24 ms:

```
explain analyze SELECT distinct room_id, membership FROM syncapi_current_room_state WHERE type = 'm.room.member' AND state_key = '@qjfl:dendrite.stg.globekeeper.com';
                                                                             QUERY PLAN

               Recheck Cond: ((type = 'm.room.member'::text) AND (state_key = '@qjfl:dendrite.stg.globekeeper.com'::text))
               Heap Blocks: exact=59
               ->  Bitmap Index Scan on syncapi_current_room_state_type_state_key_idx  (cost=0.00..4.53 rows=24 width=0) (actual time=0.037..0.037 rows=65 loops=1)
                     Index Cond: ((type = 'm.room.member'::text) AND (state_key = '@qjfl:dendrite.stg.globekeeper.com'::text))
 Planning Time: 0.236 ms
 Execution Time: 0.242 ms
(11 rows)
```

Next improvement is skipping DISTINCT and rely on map assignment in
`SelectRoomIDsWithAnyMembership`. Execution time drops by almost half:

```
explain analyze SELECT room_id, membership FROM syncapi_current_room_state WHERE type = 'm.room.member' AND state_key = '@qjfl:dendrite.stg.globekeeper.com';
                                                                       QUERY PLAN
--------------------------------------------------------------------------------------------------------------------------------------------------------

   Recheck Cond: ((type = 'm.room.member'::text) AND (state_key = '@qjfl:dendrite.stg.globekeeper.com'::text))
   Heap Blocks: exact=59
   ->  Bitmap Index Scan on syncapi_current_room_state_type_state_key_idx  (cost=0.00..4.53 rows=24 width=0) (actual time=0.021..0.021 rows=65 loops=1)
         Index Cond: ((type = 'm.room.member'::text) AND (state_key = '@qjfl:dendrite.stg.globekeeper.com'::text))
 Planning Time: 0.087 ms
 Execution Time: 0.136 ms
(7 rows)
```

In our env we spend only 1s on inserting to table, so the write penalty
of creating an index should be small.
```
dendrite_syncapi=# select total_exec_time, left(query,100) from pg_stat_statements where query like '%INSERT%syncapi_current_room_state%' order by total_exec_time desc;

bugfix: E2EE device keys could sometimes not be sent to remote servers (#2466)
* Fix flakey sytest 'Local device key changes get to remote servers'

* Debug logs

* Remove internal/test and use /test only

Remove a lot of ancient code too.

* Use FederationRoomserverAPI in more places

* Use more interfaces in federationapi; begin adding regression test

* Linting

* Add regression test

* 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.

* Unbreak new tests

* Linting
