This include is needed to compile the bpf_obj_get function properly,
as it brings in the __NR_bpf declaration.

Exercise the new kernel feature introduced in commit 2c16d6033264
("netfilter: xt_bpf: support ebpf") to load pinned eBPF programs.
The new interface allows instantiating a bpf match using
-m bpf --object-pinned ${PATH}
where ${PATH} points to a node in a bpf virtual filesystem. See
also the revised man page.

Add user-space code to support the new BPF iptables extension.
Pablo has mangled the original patch to:
* include a copy of include/linux/netfilter/xt_bpf.h in the tree.
* I have also remove the --bytecode-file option. The original
proposal was to accept BPF code in a file in human readable
format. Now, with the nfbpf_compile utility, it's very easy
to generate the filter using tcpdump-like syntax.
* I have remove the trailing comma in the backtick format, the
parser works just fine for me here.
* Fix error message if --bytecode is missing.
