Fix OIDC login regression (#17031)
Requests may require a User-Agent header, and the change in #16972
accidentally removed it, resulting in requests getting rejected causing
login to fail.

Ensure that pending to-device events are sent over federation at startup (#16925)
Fixes https://github.com/element-hq/synapse/issues/16680, as well as a
related bug, where servers which we had *never* successfully sent an
event to would not be retried.

In order to fix the case of pending to-device messages, we hook into the
existing `wake_destinations_needing_catchup` process, by extending it to
look for destinations that have pending to-device messages. The
federation transmission loop then attempts to send the pending to-device
messages as normal.

Patch the db conn pool sooner in tests (#17017)
When running unit tests, we patch the database connection pool so that
it runs queries "synchronously". This is ok, except that if any queries
are launched before we do the patching, those queries get left in limbo
and never complete.

To fix this, let's change the way we do the switcheroo, by patching out
the method which creates the connection pool in the first place.

Prevent start_for_complement.sh from setting START_POSTGRES to false when it's already set (#16985)
I have a use case where I'd like the Synapse image to start up a
postgres instance that I can use, but don't want to force Synapse to use
postgres as well.

This commit prevents postgres from being started when it has already
been explicitly enabled elsewhere.

Improve lock performance when a lot of locks are waiting (#16840)
When a lot of locks are waiting for a single lock, notifying all locks
independently with `call_later` on each release is really costly and
incurs some kind of async contention, where the CPU is spinning a lot
for not much.

The included test is taking around 30s before the change, and 0.5s
after.

It was found following failing tests with
https://github.com/element-hq/synapse/pull/16827.

Multi-worker-docker-container: disable log buffering (#16919)
Background: we have a `matrixdotorg/synapse-workers` docker image, which
is intended for running multiple workers within the same container. That
image includes a `prefix-log` script which, for each line printed to
stdout or stderr by one of the processes, prepends the name of the
process.

This commit disables buffering in that script, so that lines are logged
quickly after they are printed. This makes it much easier to understand
the output, since they then come out in a natural order.

Prevent locking up while processing batched_auth_events (#16968)
This PR aims to fix #16895, caused by a regression in #7 and not fixed
by #16903. The PR #16903 only fixes a starvation issue, where the CPU
isn't released. There is a second issue, where the execution is blocked.
This theory is supported by the flame graphs provided in #16895 and the
fact that I see the CPU usage reducing and far below the limit.

Since the changes in #7, the method `check_state_independent_auth_rules`
is called with the additional parameter `batched_auth_events`:


6fa13b4f92/synapse/handlers/federation_event.py (L1741-L1743)


It makes the execution enter this if clause, introduced with #15195


6fa13b4f92/synapse/event_auth.py (L178-L189)

There are two issues in the above code snippet.

First, there is the blocking issue. I'm not entirely sure if this is a
deadlock, starvation, or something different. In the beginning, I
thought the copy operation was responsible. It wasn't. Then I
investigated the nested `store.get_events` inside the function `update`.
This was also not causing the blocking issue. Only when I replaced the
set difference operation (`-` ) with a list comprehension, the blocking
was resolved. Creating and comparing sets with a very large amount of
events seems to be problematic.

This is how the flamegraph looks now while persisting outliers. As you
can see, the execution no longer locks up in the above function.

![output_2024-02-28_13-59-40](https://github.com/element-hq/synapse/assets/13143850/6db9c9ac-484f-47d0-bdde-70abfbd773ec)

Second, the copying here doesn't serve any purpose, because only a
shallow copy is created. This means the same objects from the original
dict are referenced. This fails the intention of protecting these
objects from mutation. The review of the original PR
https://github.com/matrix-org/synapse/pull/15195 had an extensive
discussion about this matter.

Various approaches to copying the auth_events were attempted:
1) Implementing a deepcopy caused issues due to
builtins.EventInternalMetadata not being pickleable.
2) Creating a dict with new objects akin to a deepcopy.
3) Creating a dict with new objects containing only necessary
attributes.

Concluding, there is no easy way to create an actual copy of the
objects. Opting for a deepcopy can significantly strain memory and CPU
resources, making it an inefficient choice. I don't see why the copy is
necessary in the first place. Therefore I'm proposing to remove it
altogether.

After these changes, I was able to successfully join these rooms,
without the main worker locking up:

Fix joining remote rooms when a on_new_event callback is registered (#16973)
Since Synapse 1.76.0, any module which registers a `on_new_event`
callback would brick the ability to join remote rooms.
This is because this callback tried to get the full state of the room,
which would end up in a deadlock.

Related:
https://github.com/matrix-org/synapse-auto-accept-invite/issues/18

The following module would brick the ability to join remote rooms:

```python
from typing import Any, Dict, Literal, Union
import logging

from synapse.module_api import ModuleApi, EventBase

logger = logging.getLogger(__name__)

class MyModule:
    def __init__(self, config: None, api: ModuleApi):
        self._api = api
        self._config = config

        self._api.register_third_party_rules_callbacks(
            on_new_event=self.on_new_event,
        )

    async def on_new_event(self, event: EventBase, _state_map: Any) -> None:
        logger.info(f"Received new event: {event}")

    @staticmethod
    def parse_config(_config: Dict[str, Any]) -> None:
        return None
```

This is technically a breaking change, as we are now passing partial
state on the `on_new_event` callback.
However, this callback was broken for federated rooms since 1.76.0, and
local rooms have full state anyway, so it's unlikely that it would
change anything.

Add a config to not send out device list updates for specific users (#16909)
List of users not to send out device list updates for when they register
new devices. This is useful to handle bot accounts.

This is undocumented as its mostly a hack to test on matrix.org.

Note: This will still send out device list updates if the device is
later updated, e.g. end to end keys are added.
