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.

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
We need to run the errback in the sentinel context to avoid losing our own
context.

Also: add logging to runInteraction to help identify where "Starting db
connection from sentinel context" warnings are coming from

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

a79410e7b8 Have _get_new_state_after_events return delta
If we have a delta from the existing to new current state, then we can
reuse that rather than manually working it out by fetching both lots of
state.

50c60e5fad Only get cached state from context in persist_event
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.

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).

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.

b1dfbc3c40 Refactor store.have_events
It turns out that most of the time we were calling have_events, we were only
using half of the result. Replace have_events with have_seen_events and
get_rejection_reasons, so that we can see what's going on a bit more clearly.

This will allow us to measure how often we calculate state deltas in
event persistence that we would have been able to calculate at the same
time we calculated the state for the event.
