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

This adds Sytest and Complement coverage reporting to the nightly
scheduled CI runs.
Fixes a few API mode related issues as well, since we seemingly never
really ran them with Complement.
Also fixes a bug related to device list changes: When we pass in an
empty `newlyLeftRooms` slice, we got a list of all currently joined
rooms with the corresponding members. When we then got the
`newlyJoinedRooms`, we wouldn't update the `changed` slice, because we
already got the user from the `newlyLeftRooms` query. This is fixed by
simply ignoring empty `newlyLeftRooms`.
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.

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.
Second part for guest access, this adds a `WithAllowGuests()` option to
`MakeAuthAPI`, allowing guests to access the specified endpoints.
Endpoints taken from the
[spec](https://spec.matrix.org/v1.4/client-server-api/#client-behaviour-14)
and by checking Synapse endpoints for `allow_guest=true`.
* fix#2838 by querying db directly for membership info
* fix lint error
* revert changes and use SelectMembershipForUser directly
* Remove extra membership checks
* Add a comment to explain why the membership check is necessary
Proposed fix for issue:
https://github.com/matrix-org/dendrite/issues/2838
Suppose bob received invites to spaceA and spaceB.
When Bob joins spaceA, we add an OutputEvent event to retire the invite.
This sets the invite to "deleted" in the database. This makes sense.
The bug is in stream_invites.go. Triggered when bob received a new
invite for spaceB, and does a client sync.
In the block (line 76)
`for roomID := range retiredInvites
if _, ok := req.Response.Rooms.Invite[roomID]; ok {
continue
}
if _, ok := req.Response.Rooms.Join[roomID]; ok {
continue
}
...
`
Bob is not in either maps even though he had just accepted the invite
for spaceA. Consequently, the spaceA invite is treated as a retired
invite, and a membership Leave event is generated. What bob sees is that
after accepting the invite to spaceB, he lose access to spaceA.

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.

This should stop state events disappearing down a gap where we'd try to
separate out the sections *before* applying history visibility instead
of after.
This may be a better approach than #2843 but I hope @tak-hntlabs will
shout if it isn't.
If we're going backwards, we were selecting potentially thousands of
events, which in turn were fed to history visibility checks, resulting
in bad sync performance.
The problem was that we weren't getting enough recent events, as most of
them were removed by the history visibility filter. Now we're getting
all events between the given input range and re-slice the returned
values after applying history visibility.
Makes the tests
```
Can get rooms/{roomId}/members at a given point
Can filter rooms/{roomId}/members
```
pass, by moving `/members` and `/joined_members` to the SyncAPI.

I was not seeing unread notifications in sync, even if they were written to the db
Notifications are in their own stream, but the code was trying to tack them onto the join room stream. If the offsets “happened” to line up, you might get a count here or there, but they would be totally wrong (jump from 1 to 0 to 2, etc)
To fix, put them in their own top level object, handle them on the client.

This is going to make `Can get rooms/{roomId}/messages for a departed
room (SPEC-216)` pass, since we now only grep events from before the
user left the room.
This makes the following changes:
- get state deltas without the user supplied filter, so we can actually
"calculate" state transitions
- closes `stmt` when using SQLite
- Adds presence for users who newly joined a room, even if the syncing
user already knows about the presence status (should fix
https://github.com/matrix-org/complement/pull/516)
