zebra: extern/extract some functions from rt_netlink.c
* zebra/{rib.h,zebra_rib.c}
Add nexthop_type_to_str(), which returns a human-readable string
corresponding to a nexthop type.
* zebra/rt_netlink.[hc]
- Add new header file that exposes some existing and new
netlink-related functions from rt_netlink.c to the rest of
zebra.
