0f2ecb961e Fix DoS when there is a cycle in redaction events
Make sure that synapse doesn't explode when a redaction redacts itself, or
there is a larger cycle.

Stop trying to fetch events with event_id=None. (#5753)
`None` is not a valid event id, so queuing up a database fetch for it seems
like a silly thing to do.

I considered making `get_event` return `None` if `event_id is None`, but then
its interaction with `allow_none` seemed uninituitive, and strong typing ftw.

More refactoring in get_events_as_list (#5707)
We can now use `_get_events_from_cache_or_db` rather than going right back to
the database, which means that (a) we can benefit from caching, and (b) it
opens the way forward to more extensive checks on the original event.

We now always require the original event to exist before we will serve up a
redaction.

Fix redaction authentication (#5700)
Ensures that redactions are correctly authenticated for recent room versions.

There are a few things going on here:

 * `_fetch_event_rows` is updated to return a dict rather than a list of rows.

 * Rather than returning multiple copies of an event which was redacted
   multiple times, it returns the redactions as a list within the dict.

 * It also returns the actual rejection reason, rather than merely the fact
   that it was rejected, so that we don't have to query the table again in
   `_get_event_from_row`.

 * The redaction handling is factored out of `_get_event_from_row`, and now
   checks if any of the redactions are valid.

Refactor get_events_as_list (#5699)
A couple of changes here:

* get rid of a redundant `allow_rejected` condition - we should already have filtered out any rejected
  events before we get to that point in the code, and the redundancy is confusing. Instead, let's stick in
  an assertion just to make double-sure we aren't leaking rejected events by mistake.

* factor out a `_get_events_from_cache_or_db` method, which is going to be important for a 
  forthcoming fix to redactions.

75538813fc Fix background updates to handle redactions/rejections (#5352)
* Fix background updates to handle redactions/rejections

In background updates based on current state delta stream we need to
handle that we may not have all the events (or at least that
`get_events` may raise an exception).

clearer.

c5a296b10c Add support for persisting event format versions
Currently we only have the one event format version defined, but this
adds the necessary infrastructure to persist and fetch the format
versions alongside the events.

We specify the format version rather than the room version as:

1. We don't necessarily know the room version, existing events may be
   either v1 or v2.
2. We'd need to be careful to prevent/handle correctly if different
   events in the same room reported to be of different versions, which
   sounds annoying.

667fba68f3 Run things as background processes
This fixes #3518, and ensures that we get useful logs and metrics for lots of
things that happen in the background.

(There are certainly more things that happen in the background; these are just
the common ones I've found running a single-process synapse locally).

b088aafcae Log number of events fetched from DB
When we finish processing a request, log the number of events we fetched from
the database to handle it.

[I'm trying to figure out which requests are responsible for large amounts of
event cache churn. It may turn out to be more helpful to add counts to the
prometheus per-request/block metrics, but that is an extension to this code
anyway.]
