Fix outliers whose auth_events are in a different room are correctly rejected (#2791)
Fixes `outliers whose auth_events are in a different room are correctly
rejected`, by validating that auth events are all from the same room and
not using rejected events for event auth.

Fix /get_missing_events for rooms with joined/invited history_visibility (#2787)
Sytest was using a wrong `history_visibility` for `invited`
(https://github.com/matrix-org/sytest/pull/1303), so `invited` was
passing for the wrong reason (-> defaulted to `shared`, as `invite`
wasn't understood).
This change now handles missing events like Synapse, if a server isn't
allowed to see the event, it gets a redacted version of it, making the
`get_missing_events` tests pass.

Don't perform a federated join after invite if we are already joined to the room (#2762)
If we are already joined to the room then it shouldn't matter if you

Ensure that all state event IDs are included in the added section when rewriting state (#2725)
This should hopefully fix an entire class of problems where components
downstream from the roomserver (i.e. the sync API) could just lose a
whole bunch of state after a rewrite operation like a federated join.

The root of the bug is that we set `RewritesState` in the output event
which instructs downstream components to purge their copy of any room
state, but then didn't send the entire state snapshot in
`adds_state_event_ids` so the downstream state ends up being incomplete
as a result.

Tweak LoadMembershipAtEvent behaviour when state not known (#2716)
Previously `LoadMembershipAtEvent` would fail if the state before one of
the events was not known, i.e. because it was an outlier. This modifies
it so that it gracefully handles not knowing the state and returns no
memberships instead, so that history visibility doesn't freak out and
kill `/sync` requests dead.

Check unique constraint errors when manually inserting migrations (#2712)
This should avoid unnecessary logging on startup if the migration (were
we need `InsertMigration`) was already executed.
This now checks for "unique constraint errors" for SQLite and Postgres
and fails the startup process if the migration couldn't be manually
inserted for some other reason.

Change detection of already executed migrations (#2665)
This changes the detection of already executed migrations for the
roomserver state block and keychange refactor. It now uses schema tables
provided by the database engine to check if the column was already
removed. We now also store the migration in the migrations table.

This should stop e.g. Postgres from logging errors like `ERROR: column
"event_nid" does not exist at character 8`.

bugfix: E2EE device keys could sometimes not be sent to remote servers (#2466)
* Fix flakey sytest 'Local device key changes get to remote servers'

* Debug logs

* Remove internal/test and use /test only

Remove a lot of ancient code too.

* Use FederationRoomserverAPI in more places

* Use more interfaces in federationapi; begin adding regression test

* Linting

* Add regression test

* Unbreak tests

* ALL THE LOGS

* Fix a race condition which could cause events to not be sent to servers

If a new room event which rewrites state arrives, we remove all joined hosts
then re-calculate them. This wasn't done in a transaction so for a brief period
we would have no joined hosts. During this interim, key change events which arrive
would not be sent to destination servers. This would sporadically fail on sytest.

* Unbreak new tests

* Linting

There is still an actual bug here somewhere in the membership updater, but this check does more harm than good, since it means that the key consumers don't actually distribute updates to *anyone*. It's better just to deal with this silently for now.

To find these broken rows:

```
SELECT * FROM roomserver_membership AS m WHERE NOT EXISTS (
	SELECT event_state_key_nid FROM roomserver_event_state_keys AS s
	WHERE m.sender_nid = s.event_state_key_nid
);

Remove roomserver input deadlines (#2144)
It isn't really clear that the deadlines actually help in any way. Currently we can use up our 2 minutes doing something, run out of context time and then return an error which causes the transaction to rollback and forgetting everything we've done. If the message came to us from NATS then we probably will end up retrying just to be in the same situation. We'd be really a lot better if we just spent the time reconciling the problem in the first place, and then we're much less likely to need to fetch those missing auth or prev events in the future.

Also includes matrix-org/gomatrixserverlib#287 so we don't wait so long for servers that are obviously dead.

PerformInvite: bugfix and rejig control flow (#2137)
* PerformInvite: bugfix and rejig control flow

Local clients would not be notified of invites to rooms
Dendrite had already joined in all cases due to not returning
an `api.OutputNewInviteEvent` for local invites. We now do this.

This was an easy mistake to make due to the control flow of the
function which doesn't handle the happy case at the end of the
function and instead forks the function depending on if the
invite was via federation or not. This has now been changed to
handle the federated invite as if it were an error (in that we
check it, do it and bail out) rather than outstay our welcome.
This ends up with the local invite being the happy case, which
now both sends an `InputRoomEvent` to the roomserver _and_ a
`api.OutputNewInviteEvent` is returned.

* Don't send invite pokes in PerformInvite

* Move event ID into logger

Roomserver/federation input refactor (#2104)
* Put federation client functions into their own file

* Look for missing auth events in RS input

* Remove retrieveMissingAuthEvents from federation API

* Logging

* Sorta transplanted the code over

* Use event origin failing all else

* Don't get stuck on mutexes:

* Add verifier

* Don't mark state events with zero snapshot NID as not existing

* Check missing state if not an outlier before storing the event

* Reject instead of soft-fail, don't copy roominfo so much

* Use synchronous contexts, limit time to fetch missing events

* Clean up some commented out bits

* Simplify `/send` endpoint significantly

* Submit async

* Report errors on sending to RS input

* Set max payload in NATS to 16MB

* Tweak metrics

* Add `workerForRoom` for tidiness

* Try skipping unmarshalling errors for RespMissingEvents

* Track missing prev events separately to avoid calculating state when not possible

* Tweak logic around checking missing state

* Care about state when checking missing prev events

* Don't check missing state for create events

* Try that again

* Handle create events better

* Send create room events as new

* Use given event kind when sending auth/state events

* Revert "Use given event kind when sending auth/state events"

This reverts commit 089d64d271.

* Only search for missing prev events or state for new events

* Tweaks

* We only have missing prev if we don't supply state

* Room version tweaks

* Allow async inputs again

* Apply backpressure to consumers/synchronous requests to hopefully stop things being overwhelmed

* Set timeouts on roomserver input tasks (need to decide what timeout makes sense)

* Use work queue policy, deliver all on restart

* Reduce chance of duplicates being sent by NATS

* Limit the number of servers we attempt to reduce backpressure

* Some review comment fixes

* Tidy up a couple things

* Don't limit servers, randomise order using map

* Some context refactoring

* Update gmsl

* Don't resend create events

* Set stateIDs length correctly or else the roomserver thinks there are missing events when there aren't

* Exclude our own servername

* Try backing off servers

* Make excluding self behaviour optional

* Exclude self from g_m_e

* Update sytest-whitelist

* Update consumers for the roomserver output stream

* Remember to send outliers for state returned from /gme

* Make full HTTP tests less upsetti

* Remove 'If a device list update goes missing, the server resyncs on the next one' from the sytest blacklist

* Remove debugging test

* Fix blacklist again, remove unnecessary duplicate context

* Clearer contexts, don't use background in case there's something happening there

* Don't queue up events more than once in memory

* Correctly identify create events when checking for state

* Fill in gaps again in /gme code

* Remove `AuthEventIDs` from `InputRoomEvent`

* Remove stray field

Fix #2027 by gracefully handling stub rooms (#2100)
The server ACL code on startup will grab all known rooms from
the rooms_table and then call `GetStateEvent` with each found
room ID to find the server ACL event. This can fail for stub
rooms, which will be present in the rooms table. Previously
this would result in an error being returned and the server
failing to start (!). Now we just return no event for stub
rooms.
