Title: Issue 3690 - Remove bitfield! macro in favour of bitflags!

This is my attempt at solving #3690

Initially, this is simply a naive attempt at re-rolling the changes from PR-2610. To my surprise, not only did it compile cleanly, the few local test failures I had seemed completely unrelated to what I was doing (mostly timeouts), so I'm making a PR of this.
