Add support for MSC4115 (#17104)

Ensure that incoming to-device messages are not dropped (#17127)
... when workers are unreachable, etc.

Fixes https://github.com/element-hq/synapse/issues/17117.

The general principle is just to make sure that we propagate any
exceptions to the JsonResource, so that we return an error code to the
sending server. That means that the sending server no longer considers
the message safely sent, so it will retry later.

In the issue, Erik mentions that an alternative solution would be to
persist the to-device messages into a table so that they can be retried.
This might be an improvement for performance, but even if we did that,
we still need this mechanism, since we might be unable to reach the
database. So, if we want to do that, it can be a later follow-up.

bugfix: make msc3967 idempotent (#16943)
MSC3967 was updated recently to make it more robust to network failures:

> there is an existing cross-signing master key and it exactly matches
the cross-signing master key provided in the request body. If there are
any additional keys provided in the request (self signing key, user
signing key) they MUST also match the existing keys stored on the
server. In other words, the request contains no new keys. If there are
new keys, UIA MUST be performed.


https://github.com/matrix-org/matrix-spec-proposals/blob/hughns/device-signing-upload-uia/proposals/3967-device-signing-upload-uia.md#proposal

This covers the case where the 200 OK is lost in transit so the client
retries the upload, only to then get UIA'd.

Add back fast path for non-gappy syncs (#17064)
PR #16942 removed an invalid optimisation that avoided pulling out state
for non-gappy syncs. This causes a large increase in DB usage. c.f.
#16941 for why that optimisation was wrong.

However, we can still optimise in the simple case where the events in
the timeline are a linear chain without any branching/merging of the
DAG.

Fix bug in /sync response for archived rooms (#16932)
This PR fixes a very, very niche edge-case, but I've got some more work
coming which will otherwise make the problem worse.

The bug happens when the syncing user leaves a room, and has a sync
filter which includes "left" rooms, but sets the timeline limit to 0. In
that case, the state returned in the `state` section is calculated
incorrectly.

The fix is to pass a token corresponding to the point that the user
leaves the room through to `compute_state_delta`.

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.

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.

Allow room creation but not publishing to continue if room publication rules are violated when creating a new room. (#16811)
Prior to this PR, if a request to create a public (public as in
published to the rooms directory) room violated the room list
publication rules set in the
[config](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#room_list_publication_rules),
the request to create the room was denied and the room was not created.

This PR changes the behavior such that when a request to create a room
published to the directory violates room list publication rules, the
room is still created but the room is not published to the directory.

Pull less state out if we fail to backfill (#16788)
Sometimes we fail to fetch events during backfill due to missing state,
and we often end up querying the same bad events periodically (as people
backpaginate). In such cases its likely we will continue to fail to get
the state, and therefore we should try *before* loading the state that
we have from the DB (as otherwise it's wasted DB and memory).

Reduce amount of state pulled out when querying federation hierachy (#16785)
There are two changes here:

1. Only pull out the required state when handling the request.
2. Change the get filtered state return type to check that we're only
querying state that was requested

Faster partial join to room with complex auth graph (#7)
Instead of persisting outliers in a bunch of batches, let's just do them
all at once.

This is fine because all `_auth_and_persist_outliers_inner` is doing is
checking the auth rules for each event, which requires the events to be
topologically sorted by the auth graph.

Filter out rooms from the room directory being served to other homeservers when those rooms block that homeserver by their Access Control Lists. (#16759)
The idea here being that the directory server shouldn't advertise rooms
to a requesting server is the requesting server would not be allowed to
join or participate in the room.

Simplify internal metadata class. (#16762)
We remove these fields as they're just duplicating data the event
already stores, and (for reasons 🤫) I'd like to simplify
the class to only store simple types.

I'm not entirely convinced that we shouldn't instead add helper methods
to the event class to generate stream tokens, but I don't really think
that's where they belong either
