Log Message:
- Introduce USBD_CALLBACK_AS_TASK flag, which causes the callback function
  is called as a USB_TASKQ_DRIVER task, with thread context.
  This makes sharing Ethernet drivers with FreeBSD (that requires context
  for some network-related code) much easier.
  The flag is not used by NetBSD/OpenBSD for now.

- Rename xfer->async_task as xfer->task, now used by both async xfer and the
  callback above.

- Use 0 as idle task queue ID (definition USB_TASKQ_IDLE added), and
  increase USB_TASKQ_HC and USB_TASKQ_DRIVER accordingly.
  This makes passing zero-initialized (but not initialized by usb_init_task())
  usb_task to usb_rem_task() be ignored, rather than panic the system.
