Weongyo Jeong b3974c00b5 Integrate the NDIS USB support code to CURRENT.
Now the NDISulator supports NDIS USB drivers that it've tested with
devices as follows:

  - Anygate XM-142 (Conexant)
  - Netgear WG111v2 (Realtek)
  - U-Khan UW-2054u (Marvell)
  - Shuttle XPC Accessory PN20 (Realtek)
  - ipTIME G054U2 (Ralink)
  - UNiCORN WL-54G (ZyDAS)
  - ZyXEL G-200v2 (ZyDAS)

All of them succeeded to attach and worked though there are still some
problems that it's expected to be solved.

To use NDIS USB support, you should rebuild and install ndiscvt(8) and
if you encounter a problem to attach please set `hw.ndisusb.halt' to
0 then retry.

I expect no changes of the NDIS code for PCI, PCMCIA devices.
