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`.
This ensures that the joined hosts in the federation API are correct
after the state is rewritten. This might fix some races around the time
of joining federated rooms.
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.
If the private key file is lost, it's often possible to retrieve the
public key from another server elsewhere, so we should make it possible
to configure it in that way.
First attempt at removing empty fields from `/sync` responses. Needs
https://github.com/matrix-org/sytest/pull/1298 to keep Sytest happy.

This PR queries PostgreSQL for the `max_connections` and
`superuser_reserved_connections` settings and then ensures that
Dendrite's `max_open_conns` doesn't exceed the allowed value.
This is a really common source of configuration problems and can either
result in blocking queries or deadlocks, so it seems reasonable that we
complain as loudly as possible when it happens.
Updates/adds a new multistage (build-kit) Dockerfile. (if accepted,
could make `Dockerfile.monolith` and `Dockerfile.polylith` in
`build/docker` obsolete)
There's no huge difference between the dockerfiles, except this uses a
non-root user when running the container, also doesn't copy the working
directory to the image when building.
Also adds vulnerabilities scans using
[Trivy](https://github.com/aquasecurity/trivy) for the created docker
images. (untested)
Building images is done using
```
docker build . --target image-monolith -t dendrite-monolith
docker build . --target image-polylith -t dendrite-polylith
```
As noted in the comments, only adds `dendrite-polylith-multi` to the
polylith image and all required binaries to the monolith image.
Probably needs some docs updating, if this is accepted.

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.
