Add a helper which looks for a nexthop in the cache and if not found
reads the entry from the kernel and caches it. Finally the entry is
printed.

Add a static nexthop cache in a hash with 1024 buckets and helpers to
manage it (link, unlink, find, add nexthop, del nexthop). Adding new
nexthops is done by creating a new rtnl handle and using it to retrieve
the nexthop so the helper is safe to use while already reading a
response (i.e. using the global rth).

Add a structure which describes a nexthop, it will be later used to
parse, print and cache nexthops.

Add a structure which describes a resilient nexthop group. It will be
later used for parsing.
