Figure out core/api-v1 separation

[goto-bus-stop]

Currently api-v1 contains all of the things, and it's very tightly coupled with core. There should be a meaningful separation between the two so other plugins/interfaces/ can be added by server hosts easily, while keeping everything in sync.

Ideally we'd want some multiprocess support so we can have like millions of people online and do 0-downtime server upgrades (I mean, I assume that's how it works! not an expert. But we need to be able to do that, anyway.) in the long term.
