- Added add and delete route primitives in tcpip/ninfo.c

Browse source 
- Changed signature of RouterRemoveRoute to better match the information
  provided at the time when we delete a route.
- Changed signature of RouterCreateRoute for consistency.
- Cleaned up ninfo, get route info a bit.  Removed 'bad' case, not needed.
  Made magic 2 into TDI_ADDRESS_TYPE_IP, shortened code.
- Added AddrWidenAddress to generate a network address from a target and
  netmask.
- Changed the main mib to contain the number of fib entries, not the number
  of route cache entries.
