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.
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)
Improves the control flow of `GetStateDeltas` for clarity and possibly
also fixes a bug where duplicate state delta entries could be inserted
with different memberships instead of being correctly overridden by
`join`.
Use the stream positions of the notifier, which might have advanced
since setting it at the beginning of the loop. This possibly helps in
reducing roundtrips to the SyncAPI, just because we didn't fetch the
latest data.
Also fixes a minor oversight in the receipts stream.
First attempt at removing empty fields from `/sync` responses. Needs
https://github.com/matrix-org/sytest/pull/1298 to keep Sytest happy.

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.

This now uses a transaction per stream, so that errors in one stream
don't propagate to another, and we therefore no longer need to do hacks
to reopen a new transaction after aborting a failed one.
This should transactional snapshot isolation for `/sync` etc requests.
For now we don't use repeatable read due to some odd test failures with
invites.

This doesn't fix the notification counts, they still only work about 1
out of every 5 times in my tests. I will stick with my other fix locally
