Netstat is not handling properly ROSE kernel nodes and neighbour tables.
This patch add /proc/net/rose/nodes and /proc/net/rose/neigh display in
rose_gr.c.
Code is using the same style as NetRom and AX.25 hamradio options.

This code was written in 1999 and it is operational on my AX.25 Raspbian
Linux distro dor RapsBerry Pi for years.
Committed patch is against last net-tools-2.10-alpha snapshot on
sourceforge.
