Try and drop stale extremities. (#8929)
If we see stale extremities while persisting events, and notice that
they don't change the result of state resolution, we drop them.

Remove stream ordering from Metadata dict (#8452)
There's no need for it to be in the dict as well as the events table. Instead,
we store it in a separate attribute in the EventInternalMetadata object, and
populate that on load.

This means that we can rely on it being correctly populated for any event which
has been persited to the database.

Mypy fixes for `synapse.handlers.federation` (#8422)
For some reason, an apparently unrelated PR upset mypy about this module. Here are a number of little fixes.

Add EventStreamPosition type (#8388)
The idea is to remove some of the places we pass around `int`, where it can represent one of two things:

1. the position of an event in the stream; or
2. a token that partitions the stream, used as part of the stream tokens.

The valid operations are then:

1. did a position happen before or after a token;
2. get all events that happened before or after a token; and
3. get all events between two tokens.

(Note that we don't want to allow other operations as we want to change the tokens to be vector clocks rather than simple ints)

Generate real events when we reject invites (#7804)
Fixes #2181. 

The basic premise is that, when we
fail to reject an invite via the remote server, we can generate our own
out-of-band leave event and persist it as an outlier, so that we have something
to send to the client.

Fix bug in persist events when dealing with non member types. (#7548)
`_is_server_still_joined` will throw if it is given state updates with non-user ID state keys with local user leaves. This is actually rarely a problem since local leaves almost always get persisted by themselves.

(I discovered this on a branch that was otherwise broken, so I haven't seen this in the wild)

Shuffle persist event data store functions. (#7440)
The aim here is to get to a stage where we have a `PersistEventStore` that holds all the write methods used during event persistence, so that we can take that class out of the `DataStore` mixin and instansiate it separately. This will allow us to instansiate it on processes other than master, while also ensuring it is only available on processes that are configured to write to events stream.

This is a bit of an architectural change, where we end up with multiple classes per data store (rather than one per data store we have now). We end up having:

1. Storage classes that provide high level APIs that can talk to multiple data stores.
2. Data store modules that consist of classes that must point at the same database instance.
3. Classes in a data store that can be instantiated on processes depending on config.

Increase DB/CPU perf of `_is_server_still_joined` check. (#6936)
* Increase DB/CPU perf of `_is_server_still_joined` check.

For rooms with large amount of state a single user leaving could cause
us to go and load a lot of membership events and then pull out
membership state in a large number of batches.

Reduce amount of logging at INFO level. (#6862)
A lot of the things we log at INFO are now a bit superfluous, so lets
make them DEBUG logs to reduce the amount we log by default.

When server leaves room check for stale device lists. (#6801)
When a server leaves a room it may stop sharing a room with remote
users, and thus not get any updates to their device lists. So we need to
check for this case and delete those device lists from the cache.

We don't need to do this if we stop sharing a room because the remote
user leaves the room, because we track that case via looking at
membership changes.

Delete current state when server leaves a room (#6792)
Otherwise its just stale data, which may get deleted later anyway so
can't be relied on. It's also a bit of a shotgun if we're trying to get
the current state of a room we're not in.

Erik Johnston 22a9847670 Move persist_events out from main data store.
This is in preparation for splitting out of state_groups_state from the
main store into it own one, as persisting events depends on calculating
state.
