Log when events are (unexpectedly) filtered out of responses in tests (#14213)
See https://github.com/matrix-org/synapse/pull/14095#discussion_r990335492

This is useful because when see that a relevant event is an `outlier` or `soft-failed`, then that's a good unexpected indicator explaining why it's not showing up. `filter_events_for_client` is used in `/sync`, `/messages`, `/context` which are all common end-to-end assertion touch points (also notifications, relations).

Add debug logs to figure out why an event was filtered (#14095)
Spawned while investigating https://github.com/matrix-org/synapse/issues/13944

This way we might get some more context whenever an `403 Forbidden - body: {"errcode":"M_FORBIDDEN","error":"You don't have permission to access that event."}` error is produced.

Fix 404 on /sync when the last event is a redaction of an unknown/purged event (#12905)
Currently, we try to pull the event corresponding to a sync token from the database. However, when
we fetch redaction events, we check the target of that redaction (because we aren't allowed to send
redactions to clients without validating them). So, if the sync token points to a redaction of an event
that we don't have, we have a problem.

It turns out we don't really need that event, and can just work with its ID and metadata, which
sidesteps the whole problem.

Optimise backfill calculation (#12522)

Generally this is a big rewrite of _maybe_backfill, to try and fix some of the TODOs and other problems in it. It's best reviewed commit-by-commit.

Handle outliers in /federation/v1/event (#12332)
The intention here is to avoid doing state lookups for outliers in
`/_matrix/federation/v1/event`. Unfortunately that's expanded into something of
a rewrite of `filter_events_for_server`, which ended up trying to do that
operation in a couple of places.

8e64c5a24c filter out m.room.aliases from the CS API until a better solution is specced (#6878)
We're in the middle of properly mitigating spam caused by malicious aliases being added to a room. However, until this work fully lands, we temporarily filter out all m.room.aliases events from /sync and /messages on the CS API, to remove abusive aliases. This is considered acceptable as m.room.aliases events were never a reliable record of the given alias->id mapping and were purely informational, and in their current state do more harm than good.

Discard retention policies when retrieving state
Purge jobs don't delete the latest event in a room in order to keep the forward extremity and not break the room. On the other hand, get_state_events, when given an at_token argument calls filter_events_for_client to know if the user can see the event that matches that (sync) token. That function uses the retention policies of the events it's given to filter out those that are too old from a client's view.

Some clients, such as Riot, when loading a room, request the list of members for the latest sync token it knows about, and get confused to the point of refusing to send any message if the server tells it that it can't get that information. This can happen very easily with the message retention feature turned on and a room with low activity so that the last event sent becomes too old according to the room's retention policy.

An easy and clean fix for that issue is to discard the room's retention policies when retrieving state.
