Subject: [PATCH v2 bpf-next 0/2] bpf: adding support for mapinmap in libbpf

in this patch series i'm adding a helper for libbpf which would allow
it to load map-in-map(BPF_MAP_TYPE_ARRAY_OF_MAPS and
BPF_MAP_TYPE_HASH_OF_MAPS).
first patch contains new helper + explains proposed workflow
second patch contains tests which also could be used as example of
usage

v1->v2:
 - addressing nits
 - removing const identifier from fd in new helper
 - starting to check return val for bpf_map_update_elem

  bpf: adding support for map in map in libbpf
  bpf: adding tests for mapinmap helpber in libbpf
