There are lots of cases where we can inject a User object without additional efforts. Now $wgUser is only used inside AFComputedVariable, which is a little bit harder to handle because some instances of that class are serialized in the DB, and thus we cannot easily change the constructor until T213006 is resolved. This partly copies what Ia474f02dfeee8c7d067ee7e555c08cbfef08f6a6 tried to do, but adopting a different approach for various can*() methods: they're now static methods in the AbuseFilter class, so future callers don't need to instantiate an AbuseFilterView class. This also allows to re-use those methods in an API module for editing filters (T213037). Bug: T213037 Bug: T159299 Change-Id: I22743557e162fd23b3b4e52951a649d8c21109c8
