Officially deprecate legacy BPF map definitions in libbpf. They've been slated for deprecation for a while in favor of more powerful BTF-defined map definitions and this patch set adds warnings and a way to enforce this in libbpf through LIBBPF_STRICT_MAP_DEFINITIONS strict mode flag. Selftests are fixed up and updated, BPF documentation is updated, bpftool's strict mode usage is adjusted to avoid breaking users unnecessarily. v1->v2: - replace missed bpf_map_def case in Documentation/bpf/btf.rst (Alexei).
