the load_func that typically preceeds the call. Instead, move this
inside the attach_kprobe implementation. Also, this makes attach_kprobe
need to be non-static. The same applies to attach_kretprobe.

Old:
fn = b.load_func("hello", BPF.KPROBE)
BPF.attach_kprobe(fn, "sys_clone")

New:
b.attach_kprobe(event="sys_clone", fn_name="hello")

locations of data fields. The use case is for fuse file input/output. A
printf api may follow.

Take the table with key/leaf of:

  struct Leaf { int a; int b; int c; struct SubLeaf { int x; int y; } s; };

One would input to this table using:
  update_table(table_name, "{1 2}", "{1 2 -3 {9 0xa}}");

invoked to run sscanf on behalf of the caller. The input must have the
exact right number of arguments. Bit fields are supported, but the

Also, there are some worrisome warnings during cmake when X86 target is
omitted. Additionally, I may want X86 target support for a future
feature, so lets suggest it here.

Add pkg-config support and include compat/linux* in packaging

Different kernel header versions has been a continuing source of pain.
Though I don't prefer this approach, it seems the most reliable way to
get a build (for the time being) is to bundle the linux/bpf*.h in a
compat directory in the target install location.

To get visibility into that compat directory from another library, one
will need to rely on pkg-config --cflags argument to pull in that compat
directory.

Future work will be to avoid bundling the compat directory if the
version of linux-libc-dev is high enough, or if the presence of the
result of 'make headers_install' from the running kernel can be
detected.
