e0ff66dfd9 Fix backfill being able to cleanly branch into history and back to "live" 
Fix https://github.com/matrix-org/synapse/pull/11114#discussion_r731363046

 - When we see a connected insertion event indicating a branch of history,
   we now don't accidentally leak the base event we're branching from
   in the backfill chunk until all of the events in the historical brach
   are exhausted.
 - Backfill will now check whether the federating homeserver asking
   has a given insertion event when we see one connected to the DAG.
   This allows backfill to initially decide to give all the historical
   messages in the branch, then next time when the base event we branched
   from comes up in backfill again, it sees that federated homeserver
   already has the insertion event, and we can continue down the normal
   DAG prev_event path instead.

Example Backfill response (in order yay):

Overview:
```
eventIDsAfter
batch0
batch1

9a6d8faafe WIP: Don't include the event we branch from 
We want to backfill all of the history before adding the base event.

But then there is a problem of how do we add the base event after
exhausting all of the historical messages. Backfill will give
us that extremity again but the current code will always
choose the historical branch over and over and never move past it.

I wish we could ask the federated homeserver if it already
has the insertion event locally but we can't make any requests
in the store code here :/

4191f5615f Remove fake prev events from historical state chain 
Fix https://github.com/matrix-org/synapse/issues/11091

We have to allow creation of events with no prev_events
but do have auth_events.

And since the historical member events are outliers
with no prev_events to resolve them, we want to avoid
putting them as backward extremeties.

886071b66b Fix backfill not picking up batch events connected to non-base insertion events 
Previously, we would only look for a batch event if the insertion event
was connected to something else by prev_event. This is only the case
for the base insertion event. And instead, we need to look for
a batch event whenever we come across an insertion event.

4983739156 Avoid constant missing prev_event fetching while backfilling 
Persist backfilled event response from oldest -> newest to avoid
having to go fetch missing prev_events which de-outliers every
other event and screws up the stream_ordering. Missing prev_events
aren't fetched as "backfilled" so the stream_ordering was incrementing.

This helps us in MSC2716 land where we can more easily copy a similar
stream_ordering that the originating homeserver has.

cc33d9eee2 Check auth on received events' auth_events (#11001) 
Currently, when we receive an event whose auth_events differ from those we expect, we state-resolve between the two state sets, and check that the event passes auth based on the resolved state.

This means that it's possible for us to accept events which don't pass auth at their declared auth_events (or where the auth events themselves were rejected), leading to problems down the line like #10083.

This change means we will:

 * ignore any events where we cannot find the auth events
 * reject any events whose auth events were rejected
 * reject any events which do not pass auth at their declared auth_events.

Together with a whole raft of previous work, this is a partial fix to #9595.

Fixes #6643.

Based on #11009.

a5d2ea3d08 Check *all* auth events for room id and rejection (#11009) 
This fixes a bug where we would accept an event whose `auth_events` include
rejected events, if the rejected event was shadowed by another `auth_event`
with same `(type, state_key)`.

The approach is to pass a list of auth events into
`check_auth_rules_for_event` instead of a dict, which of course means updating
the call sites.

This is an extension of #10956.
