From 447f4f0d5f136dcadd5fdc286ded2d6e24a3f686 Mon Sep 17 00:00:00 2001
From: Matthew Hodgson <matthew@matrix.org>

Subject: rewrite based on PR feedback:

 * [ ] split config options into allowed_local_3pids and registrations_require_3pid
 * [ ] simplify and comment logic for picking registration flows
 * [ ] fix docstring and move check_3pid_allowed into a new util module
 * [ ] use check_3pid_allowed everywhere
