Added skeletal version of Linux netlink interface. It doesn't work yet,

- kernel: RTM_F_NOTIFY seems to be unimplemented

- kernel: RTM_DELROUTE not announced for device routes

- netlink: import Linux route attributes to our rta's, so that they can be filtered?

Cleanup

~~~~~~~

- right usage of DBG vs. debug
