Subject: [PATCH iproute2] iplink: allow to show ip addresses

This patch adds a new option (-addresses) to the 'ip link' command so that the
user can display link details and IP addresses with the same command.

Example:
$ ip -d -a l ls gre1
9: gre1@...E: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1468 qdisc noqueue state UNKNOWN mode DEFAULT group default
    link/gre 10.16.0.249 peer 10.16.0.121 promiscuity 0
    gre remote 10.16.0.121 local 10.16.0.249 ttl inherit ikey 0.0.0.10 okey 0.0.0.10 icsum ocsum
    inet 192.168.0.249 peer 192.168.0.121/32 scope global gre1
       valid_lft forever preferred_lft forever
    inet6 fe80::5efe:a10:f9/64 scope link
       valid_lft forever preferred_lft forever
