Merge branch 'bpf-libbpf-mapinmap'

Nikita V. Shirokov says:

====================
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 usage.

v4->v5:
 - naming: renamed everything to map_in_map instead of mapinmap
 - start to return nonzero val if set_inner_map_fd failed

v3->v4:
 - renamed helper to set_inner_map_fd
 - now we set this value only if it haven't
   been set before and only for (array|hash) of maps

v2->v3:
 - fixing typo in patch description
 - initializing inner_map_fd to -1 by default

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