Get rid of two feature detectors: reallocarray and libelf-mmap. Optional feature detections complicate libbpf Makefile and cause more troubles for various applications that want to integrate libbpf as part of their build. Patch #1 replaces all reallocarray() uses into libbpf-internal reallocarray() implementation. Patches #2 and #3 makes sure we won't re-introduce reallocarray() accidentally. Patch #2 also removes last use of libbpf_internal.h header inside bpftool. There is still nlattr.h that's used by both libbpf and bpftool, but that's left for a follow up patch to split. Patch #4 removed libelf-mmap feature detector and all its uses, as it's trivial to handle missing mmap support in libbpf, the way objtool has been doing it for a while. v1->v2 and v2->v3: - rebase to latest bpf-next (Alexei).
Applied. Thanks
