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.

Introduce different autoconf interface attributes for USB drivers
matching (and handling) a whole device and those which match an
interface only. This will allow to enforce some rules, eg that
the former don't use interface information for matching or that the
latter don't modify global device state.
The previous way left too much freedom do the drivers which led to
inconsistencies and abuse.
For now, I've not changed locators and submatch rules, this will
happen later.
There should not be any change in behaviour, except in the case of
some drivers which did behave inconsistently:
if_atu, if_axe, uep: matched the configured device in the interface
stage, but did configuration again. I've converted them to match
in the device stage.
ustir, utoppy: matched in the interface stage, but only against
vendor/device information, and used any configuration/interface
without checking. Changed to match in device stage, and added
some simple code to configure and use the first interface.
If you have one of those devices, please test!

Remove the check which disallows to connect a bus powered hub to another
bus powered hub. While one can interpret the spec that way, it is not
stated clearly, and is at most a side effect of power budgeting.
Also, there are devices which don't report correctly whether they
are self powered, so the check was unreliable.

-comment out transaction translator support for now, it doesn't do more
than allocating memory, and it does wrongly use the hub's capabilities
but not the actual setting
-switch a high-speed hub to "multiple TTs" but ignore errors; since
we don't care whether there is one or multiple this is a "best effort"
thing
