RET_PTR_TO_{BTF_ID,MEM_OR_BTF_ID}_OR_NULL, from Martin KaFai Lau.
2) Fix bpf_redirect_neigh() helper API before it becomes frozen by adding
nexthop information as argument, from Toke Høiland-Jørgensen.
3) Guard & fix compilation of bpf_tail_call_static() when __bpf__ arch is
not defined by compiler or clang too old, from Daniel Borkmann.
4) Remove misplaced break after return in attach_type_to_prog_type(), from
Tom Rix.
