This patch moves the following files in /proc:
	/proc/net/rt_cache_stat 	/proc/net/stat/rt_cache
	/proc/net/ip_conntrack_stat	/proc/net/stat/ip_conntrack
	/proc/net/arp_cache_stat	/proc/net/stat/arp_cache
	/proc/net/clip_arp_cache_stat	/proc/net/stat/clip_arp_cache
	/proc/net/dn_neigh_cache_stat	/proc/net/stat/dn_neigh_cache

This allows a generic statistics tool to scan for all available statistics
by doing readdir(2) on /proc/net/stat

It also adds a special first 'template' line to rt_cache and ip_conntrack
in order to facilitate compatibility once somebody adds new fields to the
output lines.

WARNING: 
	This breaks existing rtstat.c and ctstat.c userspace programs
	(hopefully for the last time).  rtstat is non-existant or broken in
	major distributions anyway, and ctstat is too new for any distros
	having it picked up.  Therefore, we justify this breakage.

A new unified statistics tool for routing cache, connection tracking and
neighbour cache is under development and will be included with iproute2.
