Curt Brune 69934701fd networking: add 'ip neigh' command
This patch ports the 'ip neigh' command, originally written by Alexey
Kuznetsov, <kuznet@ms2.inr.ac.ru>, to busybox.

The base of the port is the version of iproute that shipped with
Debian Squeeze, taken from:

  http://http.debian.net/debian/pool/main/i/iproute/iproute_20100519.orig.tar.gz

This patch has actively been used by the Open Network Install
Environment (ONIE) project for over 3 years without incident.
