There are only three users which require it to be reentrant, the rest is
fine without. Instead, provide a reentrant format_host_r() for users
which need it.

There have been several instances where response from kernel
has overrun the stack buffer from the caller. Avoid future problems
by passing a size argument.
Also drop the unused peer and group arguments to rtnl_talk.
Where used in the ip tool, the 'show' option always has the synonyms
'list' and 'lst', except for ip-token and ip-addrlabel, which are missing
'lst'. Add this as a synonym for these commands.

This patch adds support for tokenized IIDs, that enable
administrators to assign well-known host-part addresses
to nodes whilst still obtaining global network prefix
from Router Advertisements. This is the iproute2 part for
the kernel patch f53adae4eae5 (``net: ipv6: add tokenized
interface identifier support'').
Example commands with iproute2:
Setting a device token:
# ip token set ::1a:2b:3c:4d/64 dev eth1
Getting a device token:
# ip token get dev eth1
token ::1a:2b:3c:4d dev eth1
Listing all tokens:
# ip token list (or: ip token)
token :: dev eth0
token ::1a:2b:3c:4d dev eth1
