Sebastian Sumpf 716eab21e3 usb_drv: change Usb session and raw driver
- Use 'label' attribute to identify device instead of
  bus/dev and vendor_id/product_id

- Implement release_interface RPC

- Report 'label' as well as 'bus' and 'dev'

- Add policy handling to raw driver (includes reconfiguration
  at runtime)

- Use own memory backing store for large DMA allocations

Issue #1863.
