Closes HNT-244.
The following PR implements Space,Channel soft deletion using on-chain
`disabled` flag scope to space, channel respectively. On message sync,
dendrite will now gate disabled rooms by performing a leave on the user
attempting to sync unless the user is the owner (more on this later). To
re-join, given rooms (spaces,channels) are created by default using
`invite` membership state, the owner will need to undo the on-chain
`disabled` flag, setting it false then re-invite users that left the
room as a side effect of it becoming disabled previously.
The owner does not leave the space, channel because if they did then
there would be no one left to invite users let alone themselves back in
if the action is ever undone.
What is not implemented in this PR:
1. **Transitive leaves on channels in a space** - If a space is
disabled, users will leave the space but not the channels within the
space. To allow for fully disabling a space and all its' channels, the
client can offer a view to the owner that iterates over the channels and
space to disable all on-chain. Furthermore, we could implement a batch
on-chain method that fully disables all channels within a space (plus
the space) in one on-chain call to save the owner gas.
2. **Data deletion** - No data is remove from the DAGs or on-chain.
Therefore deletion is soft and reversible.
3. **New hook to check if a room is disabled** - the client can leverage
existing on-chain public read only methods `getSpaceInfoBySpaceId`,
`getChannelInfoByChannelId` to read the state of each in order to remove
spaces, channels from a member's view that are disabled.
Some tweaks for the send-to-device consumers/producers:
- use `json.RawMessage` without marshalling it first
- try further devices (if available) if we failed to `PublishMsg` in the
producers
- some logging changes (to better debug E2EE issues)
- Reverts 9dc57122d9 as it was causing issues https://github.com/matrix-org/dendrite/issues/2660
- Updates the GMSL `DefaultStateFilter` to use a limit of 20 events
- Uses the timeline events to determine the new position instead of the state events

* bugfix: fix race condition when updating presence via /sync
Previously when presence is updated via /sync, we would send the presence update
asyncly via NATS. This created a race condition:
- If the presence update is processed quickly, the /sync which triggered the presence
update would see an online presence.
- If the presence update was processed slowly, the /sync which triggered the presence
update would see an offline presence.
This is the root cause behind the flakey sytest: 'User sees their own presence in a sync'.
The fix is to ensure we update the database/advance the stream position synchronously
for local users.
* Bugfix for test
* 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
* Add very basic syncapi tests
* Add a way to inject jetstream messages
* implement add_state_ids
* bugfixes
* Unbreak tests
* Remove now un-needed API call
* Linting
