attach and detach events.

The commit message from NetBSD was:
        date: 2000/02/02 07:34:00;  author: augustss;  state: Exp;
        Change the USB event mechanism to include more information
        about devices and drivers.  Partly from FreeBSD.

Also rework usbd to take these new event types into account.
