[RFC][PATCH iproute2-next 0/6] ip: Use netlink to walk through network device list

[Serhey Popovych <serhe.popovych@gmail.com>]

In this seris I replace /proc/net/dev and /sys/class/net usage for walk
through network device list in iptunnel/ip6tunnel and iptuntap by
rtnl_dump_filter() functionality.

This is an RFC, tested minimally tunnels, tuntap seems work as before.

Note that some comments, especially for iptunnel/ip6tunnel commit are
missing: will add this in final series, as well as update cover letter.

Thanks,
Serhii
