Anything that wants to be "central" right now has to depend on CentralAuth, and then either can't work without CentralAuth or has to branch all over the place based on whether CentralAuth is present. Most of the time all it really needs is a mapping from local users to central user IDs and back or the ability to query whether the local user is attached on some other wiki, so let's make an interface for that in core. See I52aa0460 for an example implementation (CentralAuth), and Ibd192e29 for an example use (OAuth). Bug: T111302 Change-Id: I49568358ec35fdfd0b9e53e441adabded5c7b80f
