Ensures up to date keys for a list of users are stored in the session store, downloading and storing them if they're not (or if forceDownload is true).

the user to list keys for.
Mark the cached device list for the given user outdated.
If we are not tracking this user's devices, we'll do nothing. Otherwise we flag the user as needing an update.
This doesn't actually set off an update, so that several users can be batched together. Call refreshOutdatedDeviceLists() for that.
Optional event: EventEmitterEvents | EmittedEventsSave the device tracking state to storage, if any changes are pending other than updating the sync token
The actual save will be delayed by a short amount of time to aggregate multiple writes to the database.
true if the data was saved, false if it was not (eg. because no changes were pending). The promise will only resolve once the data is saved, so may take some time to resolve.
Time in ms before which the save actually happens. By default, the save is delayed for a short period in order to batch multiple writes, but this behaviour can be disabled by passing 0.

the user to get data for
deviceId->{object} the new devices
Sets the sync token that the app will pass as the 'since' to the /sync endpoint next time it syncs. The sync token must always be set after any changes made as a result of data in that sync since setting the sync token to a newer one will mean those changed will not be synced from the server if a new client starts up with that data.
The sync token
flag the given user for device-list tracking, if they are not already.
This will mean that a subsequent call to refreshOutdatedDeviceLists() will download the device list for the user, and that subsequent calls to invalidateUserDeviceList will trigger more updates.
Mark the given user as no longer being tracked for device-list updates.
This won't affect any in-progress downloads, which will still go on to complete; it will just mean that we don't think that we have an up-to-date list for future calls to downloadKeys.
