61ffaa8137 bump purge logging to info
this thing takes ages and the only sign of any progress is the logs, so having
some logs is useful.

671540dccf rename delete_old_state -> purge_history

Store state groups separately from events (#2784)
* Split state group persist into seperate storage func

* Add per database engine code for state group id gen

* Move store_state_group to StateReadStore

This allows other workers to use it, and so resolve state.

* 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

ee6fb4cf85 Remove redundant return value from _calculate_state_delta
we already have the state from _get_new_state_after_events, so returning it
from _calculate_state_delta is just confusing.

b387ee17b6 Improve exception handling in persist_event
1. use `deferred.errback()` instead of `deferred.errback(e)`, which means that
a Failure object will be constructed using the current exception state,
*including* its stack trace - so the stack trace is saved in the Failure,
leading to better exception reports.

2. Set `consumeErrors=True` on the ObservableDeferred, because we know that
there will always be at least one observer - which avoids a spurious "CRITICAL:
unhandled exception in Deferred" error in the logs

64ddec1bc0 Fix a logcontext leak in persist_events
ObserveableDeferred expects its callbacks to be called without any
logcontexts, whereas it turns out we were calling them with the logcontext of
the request which initiated the persistence loop.

It seems wrong that we are attributing work done in the persistence loop to the
request that happened to initiate it, so let's solve this by dropping the
logcontext for it.

(I'm not sure this actually causes any real problems other than messages in the
debug log, but let's clean it up anyway)

6cfee09be9 Make __init__ consitstent across Store heirarchy
Add db_conn parameters to the `__init__` methods of the *Store classes, so that
they are all consistent, which makes the multiple inheritance work correctly
(and so that we can later extract mixins which can be used in the slavedstores)

197bd126f0 Fix bug where state_group tables got corrupted
This is due to the fact that we prefilled caches using txn.call_after,
which always gets called including on error.

We fix this by making txn.call_after only fire when a transaction
completes successfully, which is what we want most of the time anyway.

0c01f829ae Avoid resetting state on rejected events
When we get a rejected event, give it the same state_group as its prev_event,
rather than no state_group at all.

5068fb16a5 Refactoring and cleanups
A few non-functional changes:

* A bunch of docstrings to document types
* Split `EventsStore._persist_events_txn` up a bit. Hopefully it's a bit more
  readable.
* Rephrase `EventFederationStore._update_min_depth_for_room_txn` to avoid
  mind-bending conditional.
* Rephrase rejected/outlier conditional in `_update_outliers_txn` to avoid
  mind-bending conditional.

9040c9ffa1 Fix background reindex of origin_server_ts
The storage function `_get_events_txn` was removed everywhere except
from this background reindex. The function was removed due to it being
(almost) completely unused while also being large and complex.
Therefore, instead of resurrecting `_get_events_txn` we manually
reimplement the bits that are needed directly.
