This patch adds BTF_KIND_FUNC and BTF_KIND_FUNC_PROTO to support the function debug info. BTF_KIND_FUNC_PROTO must not have a name (i.e. !t->name_off) and it is followed by >= 0 'struct bpf_param' objects to describe the function arguments. The BTF_KIND_FUNC must have a valid name and it must refer back to a BTF_KIND_FUNC_PROTO. The above is the conclusion after the discussion between Edward Cree, Alexei, Daniel, Yonghong and Martin. By combining BTF_KIND_FUNC and BTF_LIND_FUNC_PROTO, a complete function signature can be obtained. It will be used in the later patches to learn the function signature of a running bpf program.
