	src/sys/dev/usb: uhub.c

Log Message:
Keep track of the per-port status change notifications coming in
through the interrupt pipe; during exploration check only the ports
where we got such a notification. This speeds up things.
(I believe we should go a step further and use a thread per hub
instead of per bus. If power management gets implemented, we should
be able to react quickly on a resume event.)
Try to simplify the logics in the explore function a bit. (The reattach
thing was hacked in badly, not sure whether I broke it. Only used
by if_atu.)
Clean up some dead code.
