Before, processConnection wanted to know a user name and user id, and `nix-daemon --stdio`, when it isn't proxying to an underlying daemon, would just assume "root" and 0. But `nix-daemon --stdio` (no proxying) shouldn't make guesses about who holds the other end of its standard streams. Now processConnection takes an "auth hook", so `nix-daemon` can provide the appropriate policy and daemon.cc doesn't need to know or care what it is.
