More work towards removing the massive ipnserver.Run and ipnserver.Options and making composable pieces. Work remains. (The getEngine retry loop on Windows complicates things.) For now some duplicate code exists. Once the Windows side is fixed to either not need the retry loop or to move the retry loop into a custom wgengine.Engine wrapper, then we can unify tailscaled_windows.go too.
