$user is guaranteed to be a User object.
Also, while we're here:
* Remove an unnecessary TODO. There's no need for a more specific
error message, this one is just fine, other extensions use it too.
* Replace isAnon() with !isRegistered(). It'll probably be deprecated
soon, because the new UserIdentity interface doesn't include it.

For automatic topic subscriptions, I plan to introduce a third
subscription state to indicate them. This patch includes minor tweaks
I wanted to add while working on that:
* Introduce constants instead of numbers
* Remove a TODO that doesn't seem like a good idea any more
* Remove a `"length": 1` on sub_state that did not do anything
(but it might have been meant to indicate that it was supposed
to be a boolean, which would be wrong)

…without making the topic subscriptions feature available in user preferences.

Per Manuel Arostegui in T263817#7033384. The limit is 5000.
(I picked it arbitrarily, there's no real rationale for it.)
Also log a warning when any user reaches half of the limit,
so that we might make a decision about changing this mechanism
before it starts affecting users. Maybe at that time we'll
have data to show that it's safe to remove the limit.
