This initial commit added the following files
from bpf-next repository:
src:
<files from linux:tools/lib/bpf>
bpf.c bpf.h btf.c btf.h libbpf.c libbpf.h
libbpf_errno.c netlink.c nlattr.c nlattr.h
str_error.c str_error.h
include:
<files from linux:tools/include/uapi/linux>
uapi/linux/{bpf.h, btf.h}
<files from linux:tools/include/tools>
tools/libc_compat.h
The following files are also added:
include/linux/{err.h, kernel.h, list.h, overflow.h, types.h}
These files are customized headers to satisfy compilation.
