- Correct one aspect of the driver_object/device_object/IRP framework:

when we create a PDO, the driver_object associated with it is that
  of the parent driver, not the driver we're trying to attach. For
  example, if we attach a PCI device, the PDO we pass to the NdisAddDevice()
  function should contain a pointer to fake_pci_driver, not to the NDIS
  driver itself. For PCI or PCMCIA devices this doesn't matter because
  the child never needs to talk to the parent bus driver, but for USB,
  the child needs to be able to send IRPs to the parent USB bus driver, and
  for that to work the parent USB bus driver has to be hung off the PDO.

  This involves modifying windrv_lookup() so that we can search for
  bus drivers by name, if necessary. Our fake bus drivers attach themselves
  as "PCI Bus," "PCCARD Bus" and "USB Bus," so we can search for them
  using those names.

  The individual attachment stubs now create and attach PDOs to the
  parent bus drivers instead of hanging them off the NDIS driver's
  object, and in if_ndis.c, we now search for the correct driver
  object depending on the bus type, and use that to find the correct PDO.

  With this fix, I can get my sample USB ethernet driver to deliver
  an IRP to my fake parent USB bus driver's dispatch routines.

- Add stub modules for USB support: subr_usbd.c, usbd_var.h and
  if_ndis_usb.c. The subr_usbd.c module is hooked up the build
  but currently doesn't do very much. It provides the stub USB
  parent driver object and a dispatch routine for
  IRM_MJ_INTERNAL_DEVICE_CONTROL. The only exported function at
  the moment is USBD_GetUSBDIVersion(). The if_ndis_usb.c stub
  compiles, but is not hooked up to the build yet. I'm putting
  these here so I can keep them under source code control as I
  flesh them out.
