Add btf__type_cnt() and btf__raw_data() APIs and deprecate
btf__get_nr_type() and btf__get_raw_data() since the old APIs
don't follow libbpf naming convention. Also update tools/selftests
to use these new APIs. This is part of effort towards libbpf v1.0

v1->v2:
 - Update commit message, deprecate the old APIs in libbpf v0.7 (Andrii)
 - Separate changes in tools/ to individual patches (Andrii)

Hengqi Chen (5):
  libbpf: Add btf__type_cnt() and btf__raw_data() APIs
  perf bpf: Switch to new btf__raw_data API
  tools/resolve_btfids: Switch to new btf__type_cnt API
  bpftool: Switch to new btf__type_cnt API
  selftests/bpf: Switch to new btf__type_cnt/btf__raw_data APIs

Applied to bpf-next, thanks.
