[IPROUTE2] Generic netlink interface

very quiet today ..

Stephen,
I've been sitting on this for a while now; just tested against latest
kernels. 

Another one on top of the other i.e against iproute2-git.

Shailabh, if you have time can you try just listing things, monitoring
etc; I dont think your tool fits here - but if you could try and use the
framework (cutnpaste from ctrl.c) and provide feedback i would
appreciate it.
