Hooks the USB transfer taps at two points that one of them is at
usbd_pipe_start() where is a location before calling the host
controller-dependent code which normally enqueues a xfer into scheduler
then adds it into the interrupt queue.   It means it hooks all USB
transfers before going into the interrupt queue.  Other is at
usbd_callback_wrapper() where is a function to call the
developer-defined callback with status, USB_ST_TRANSFERRED or
USB_ST_ERROR that we don't tap if the status is USB_ST_SETUP.

Currently sizeof(struct usbpf_pkthdr) == 128 bytes for further works.
