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.

This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

* coreutils.h: remove prototype of non-existing xgetoptfile_sort_uniq
and add boilerplate.
* networking/{ipaddr,ip,iplink,iproute,iptunnel}.c: touch includes
and use short boilerplate.
* libiproute/iproute.c: rename round to avoid clashes with older
SuSE gcc and use short boilerplate.
