Rate limiting in Synapse used to reset the burst count and remove
the backoff when you were spamming continuously, now it doesn't.
Ideally we'd rewrite the rate limiting logic to back off for longer
than suggested so we could get burst again, but for now
lets just unblock CI by reducing the number of events we send in these
tests.
Seriously, I don't think there is much to gain by making people guess
a reasnoble time for a test to complete in all the time, especially
with how much Synapse changes in response time and all of the machines
involved in running these tests.
So the test before sometimes sent the report *before*
the protection (that is used to check whether we have received
the report) was registered.
This of course meant that we didn't ever receive the report from
the perspectivee of the test.
This PR should now mean we always send the report after
registering the protection.
This pull requests adds for glob support in the `!mjolnir kick` command.
## Example
```
!mjolnir kick @*:domain.tld <reason> --force
```
This command will kick every user having a mxid matching `domain.tld`.
You can also still kick a particular user:
```
!mjolnir kick @user:domain.tld <reason>
```
## Tests:
Tested on the Furry Tech room (`vRGLvqJYlFvzpThbxI:matrix.org`) after a spam wave.
It kicked over 13k bots in a matter of hours without putting too much strain on the homeserver.
For instance, this command was matching `@spam*`:

* Remove the need to call `/initialSync` in `getMessagesByUserIn`.
At the moment we call `/initialSync` to give a `from` token to `/messages`.
In this PR we instead do not provide a `from` token when calling `/messages`,
which has recently been permitted in the spec
Technically this is still unstable in the spec
https://spec.matrix.org/unstable/client-server-api/#get_matrixclientv3roomsroomidmessageshttps://github.com/matrix-org/matrix-spec/pull/1002
Synapse has supported this for over 2 years and Element web depends on it for threads.
https://github.com/matrix-org/matrix-js-sdk/pull/2065
Given that redactions are super heavy in Mjolnir already and have been reported
as barely functional on matrix.org I believe we should also adopt this approach as
if for some reason the spec did change before the next release (1.3) (extremely unlikely) we can revert this commit.
* Have the callback work on the packed event Obj.
And also explicitly pack the Mjolnir object inside the event.
* Add VS ignores.
* Commit suggested review changes.
- Add bind to callback
- Add type cast for event packed object
* Fix missing parenthesis.
* Don't pass Mjolnir obj to handleReport().

The reason we want this is so that people do not forget to change the version number in the synapse module.
The precedent is that the version number has been 0.1.0 since the begging until now.
While this solution does mean that there may be new version of the module where
nothing has actually changed, this is still better than not changing the version at all.
Another version scheme for the module would be inconsistent to
the git repository tags and that has the potential to cause much more confusion
than "blank" version bumps.
If this is a problem, then antispam must be extracted to another repository.
In order to test this, run `yarn version --patch` observe the changes with `git log` and `git diff HEAD~`,
then YOU MUST delete the tag with `git tag --delete vd.d.d` when you are finished.
* more robust
There is no reason to call process.exit() from `index.ts` or in `Mjolnir.start()` because
https://nodejs.org/api/process.html#warning-using-uncaughtexception-correctly
>The 'uncaughtException' event is emitted when an uncaught JavaScript exception bubbles all the way back to the event loop. By default, Node.js handles such exceptions by printing the stack trace to stderr and exiting with code 1, overriding any previously set process.exitCode. Adding a handler for the 'uncaughtException' event overrides this default behaviour.
* Move message_limit into antispam.
https://github.com/matrix-org/message_limit
Not ideal but we've had complaints about keeping them separate
and unfortunately the need for this module is not going to go away.
* standard protection consequences
* add integration test to make sure good users aren't banned
* the less far `event` propagates, the better
* better document consequence.ts
* improve innocent user integration test
* switch to room.event emit
* Test for batching ACL.
* Batch events from sync within BanList.
* Introduce the BanList.batch event to the BanList emitter to let Mjolnir sync after new events have been added from sync.
