ca9bc1f4fe Fix occasional glitches in the synapse_event_persisted_position metric
Every so often this metric glitched to a negative number. I'm assuming it was
due to backfilled events.

5c1d301fd9 Stop populating events.content
This field is no longer read from, so we should stop populating it. Once we're
happy that this doesn't break everything, and a rollback is unlikely, we can
think about dropping the column.

bd4b25f4d0 Remove some redundant joins on event_edges.room_id
We've long passed the point where it's possible to have the same event_id in
different tables, so these join conditions are redundant: we can just join on
event_id.

event_edges is of non-trivial size, and the room_id column is wasteful, so
let's stop reading from it. In future, we can stop writing to it, and then drop
it.

21e878ebb6 Make EventStore inherit from EventFederationStore
(since it uses methods therein)

Turns out that we had a bunch of things which were incorrectly importing
EventWorkerStore from events.py rather than events_worker.py, which broke once
I removed the import into events.py.

1be94440d3 Fix occasional 'tuple index out of range' error
This fixes a bug in _delete_existing_rows_txn which was introduced in #3435
(though it's been on matrix-org-hotfixes for *years*). This code is only called
when there is some sort of conflict the first time we try to persist an event,
so it only happens rarely. Still, the exceptions are annoying.

07defd5fe6 Fix another logcontext leak in _persist_events

ec56121b0d Correctly handle outliers during persist events
We incorrectly asserted that all contexts must have a non None state
group without consider outliers. This would usually be fine as the
assertion would never be hit, as there is a shortcut during persistence
if the forward extremities don't change.

However, if the outlier is being persisted with non-outlier events, the
function would be called and the assertion would be hit.

Fixes #3601

We don't want to bother pulling out the current state from the DB since
until we know we have to. Checking the context for state is just an
optimisation.

the common ones I've found running a single-process synapse locally).

6e10eed28e Refactor event storage to not require state
This is in preparation for using contexts that may or may not have the
current_state_ids set. This will allow us to avoid unnecessarily pulling
out state for an event on the master process when using workers.

We also add a check to see if the state groups of the old extremities
are the same as the new ones.

get_rejection_reasons, so that we can see what's going on a bit more clearly.

8cb44da4aa Fix race in sync when joining room
The race happens when the user joins a room at the same time as doing a
sync. We fetch the current token and then get the rooms the user is in.
If the join happens after the current token, but before we get the rooms
we end up sending down a partial room entry in the sync.

This is fixed by looking at the stream ordering of the membership
returned by get_rooms_for_user, and handling the case when that stream
ordering is after the current token.

* Split state group persist into seperate storage func

* Add per database engine code for state group id gen

* Move store_state_group to StateReadStore

* Hook up store_state_group

* Fix tests

* Rename _store_mult_state_groups_txn

* Rename StateGroupReadStore

* Remove redundant _have_persisted_state_group_txn

* Update comments

* Comment compute_event_context

* Set start val for state_group_id_seq

... otherwise we try to recreate old state groups

* Update comments

* Don't store state for outliers

* Update comment

* Update docstring as state groups are ints
