This is huge for a single commit, and pretty much impossible to review
as-is.
Any chance you can turn this into a series of commits, that starts with
the basics and builds on top of that? Right now you are mixing many
many different subsystems all at once into one commit, guaranteeing that
no one can review the whole thing properly :(
