usb-ids: className/interfaceName helpers; readable device classes in the bus log

Browse Source 
The logs read 'class 9/0/0' where they could say 'Hub'. usb-ids gains
className (a device/interface class byte -> 'Hub', 'HID', 'Mass Storage',
...) and interfaceName (a HID boot interface -> 'HID boot keyboard' /
'HID boot mouse'), both host-tested with usb-ids. The bus driver's
enumerate + register lines now read, e.g.:

  port 21 device: Hub vendor 0x05e3 product 0x0626, 1 interface(s)
  port 21 interface 0: Hub (9/0/0) registered as device 47
  port 5 interface 0: HID boot keyboard (3/1/1) registered as device 32

so a real-hardware log is scannable by eye. Full USB case set green
(hub regexes follow the new 'device: <name>' format).
