Subject: [PATCH bpf-next 0/2] tools/bpf: expose several libbpf API functions

This patch set exposed a few functions in libbpf.
All these newly added API functions are helpful for
JIT based bpf compilation where .BTF and .BTF.ext
are available as in-memory data blobs.

Patch #1 exposed several btf_ext__* API functions which
are used to handle .BTF.ext ELF sections.
Patch #2 refactored the function bpf_map_find_btf_info()
and exposed API function btf__get_map_kv_tids() to
retrieve the map key/value type id's generated by
bpf program through BPF_ANNOTATE_KV_PAIR macro.

Yonghong Song (2):
  tools/bpf: expose functions btf_ext__* as API functions
  tools/bpf: implement libbpf btf__get_map_kv_tids() API function
