libbpf: make sure bpf headers are c++ include-able
Wrap headers in extern "C", to turn off C++ mangling. This simplifies including libbpf in c++ and linking against it. v2 changes: * do the same for btf.h v3 changes: * test_libbpf.cpp to test for possible future c++ breakages Signed-off-by: Stanislav Fomichev <sdf@google.com> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
