Merge from NetBSD.
uhub.c: revision 1.37 usb.4: revision 1.30 usb.c: revision 1.38 usb.h: revision 1.40 usb_port.h: revision 1.21 usb_subr.c: revision 1.65 usbdi.h: revision 1.40 Split the attach/detach events up into device, driver and controller 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.
