As part of the effort to move towards a v1.0 for libbpf [0], this set improves some confusing function names related to BTF loading from and to the kernel: - btf__load() becomes btf__load_into_kernel(). - btf__get_from_id becomes btf__load_from_kernel_by_id(). - A new version btf__load_from_kernel_by_id_split() extends the former to add support for split BTF. The old functions are not removed yet, but marked as deprecated. The last patch is a trivial change to bpftool to add support for dumping split BTF objects by referencing them by their id (and not only by their BTF path).
