ip.c route change support for extended attributes.

This fixes the extended attribute settings for the ip route change
command; extended attributes are collected in a separate buffer
and added to the RTM message in a specific RTA_METRICS attribute.
Only added setter support for the RTAX_MTU (per-route MTU), as that
was the only option currently parsed.

Also added support for displaying extended attributes, even those
not currently settable.
