tools lib bpf: Copy bpf.h and bpf_common.h from the kernel

2016-07-12T18:20:32+00:00

To allow the build to complete on older systems, where those files are
either not uptodate, lacking some recent additions or not present at
all.

And check if the copy drifts from the kernel, as in this synthetic test:

    BUILD:   Doing 'make -j4' parallel build
  Warning: tools/include/linux/bpf.h differs from kernel
  Warning: tools/include/linux/bpf_common.h differs from kernel

tools lib bpf: Rename set_private() to set_priv()

2016-06-06T21:19:49+00:00

For consistency with class__priv() elsewhere, and with the callback
typedef for clearing those areas (e.g. bpf_map_clear_priv_t).

tools lib bpf: Remove _get_ from non-refcount method names

2016-06-06T21:19:25+00:00

The use of this term is not warranted here, we use it in the kernel
sources and in tools/ for refcounting, so, for consistency, rename them.
