Subject: [PATCH] Refactor imports

Clean up some imports, only do the ones that we are about to touch.

- Remove/add whitespace to group by crate
- move modules/types to their module instead of using lib wide
  re-export (this helps minimise future merge conflicts)

Re-order imports, refactor only. No logic changes.
