886e5acc76 Store rejected remote invite events as outliers 
Currently they're stored as non-outliers even though the server isn't in
the room, which can be problematic in places where the code assumes it
has the state for all non outlier events.

In particular, there is an edge case where persisting the leave event
triggers a state resolution, which requires looking up the room version
from state. Since the server doesn't have the state, this causes an
exception to be thrown.

c5a296b10c Add support for persisting event format versions 
Currently we only have the one event format version defined, but this
adds the necessary infrastructure to persist and fetch the format
versions alongside the events.

We specify the format version rather than the room version as:

1. We don't necessarily know the room version, existing events may be
   either v1 or v2.
2. We'd need to be careful to prevent/handle correctly if different
   events in the same room reported to be of different versions, which
   sounds annoying.

2557531f0f Fix bug when removing duplicate rows from user_ips 
This was caused by accidentally overwritting a `last_seen` variable
in a for loop, causing the wrong value to be written to the progress
table. The result of which was that we didn't scan sections of the table
when searching for duplicates, and so some duplicates did not get
deleted.

25dd56ace3 Fix race when persisting create event (#4404) 
* Fix race when persisting create event

When persisting a chunk of DAG it is sometimes requried to do a state
resolution, which requires knowledge of the room version. If this
happens while we're persisting the create event then we need to use that
event rather than attempting to look it up in the database.

b1a22b24ab Fix noop checks when updating device keys 
Clients often reupload their device keys (for some reason) so its
important for the server to check for no-ops before sending out device
list update notifications.

The check is broken in python 3 due to the fact comparing bytes and
unicode always fails, and that we write bytes to the DB but get unicode
when we read.

88e5ffe6fe Deduplicate device updates sent over replication 
We currently send several kHz of device list updates over replication
occisonally, which often causes the replications streams to lag and then
get dropped.

A lot of those updates will actually be duplicates, since we don't send
e.g. device_ids across replication, so let's deduplicate it when we pull
them out of the database.

Refactor state group lookup to reduce DB hits (#4011) 
Currently when fetching state groups from the data store we make two
hits two the database: once for members and once for non-members (unless
request is filtered to one or the other). This adds needless load to the
datbase, so this PR refactors the lookup to make only a single database
hit.

* use `r""` for strings which include backslashes

Also, we don't use pep8 any more, so we can get rid of the duplicate config
there.

fc0f13dd03 Fix incorrect truncation in get_missing_events 
It's quite important that get_missing_events returns the *latest* events in the

least* 10, and then taking the *earliest* of the results.

We also shouldn't really be relying on depth, and should be checking the
room_id.

b9158ac2bf Remove get_destination_retry_timings cache 
Currently we rely on the master to invalidate this cache promptly.
However, after having moved most federation endpoints off of master this
no longer happens, causing outbound fedeariont to get blackholed.

Fixes #3798

Split the state_group_cache in two (#3726) 
Splits the state_group_cache in two.

One half contains normal state events; the other contains member events.

The idea is that the lazyloading common case of: "I want a subset of member events plus all of the other state" can be accomplished efficiently by splitting the cache into two, and asking for "all events" from the non-members cache, and "just these keys" from the members cache.  This means we can avoid having to make DictionaryCache aware of these sort of complicated queries, whilst letting LL requests benefit from the caching.

Previously we were unable to sensibly use the caching and had to pull all state from the DB irrespective of the filtering, which made things slow.  Hopefully fixes https://github.com/matrix-org/synapse/issues/3720.
