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.

We need to rewind skb pointers when we forward a packet to other host
because dst_input() assumes that skb->data points head of ipv6 protocol header.

Report parent classid of a qdisc back to userspace. Without this there
is no way for userspace to see if the qdisc is attached to a class
other than parsing all class trees of the link and check all tcm_info
fields in the leaf classes.

There's an issue with bio_uncopy_user() in that it expects ->bv_len to
be untouched from io submission to io completion, which it wont be for
some transfer lengths on some hardware. So we end up not copying all the
data back to user space, not so good. This patch adds a bio_map_data
local structure to track the io_vec.
