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.

tools lib bpf: Use IS_ERR() reporting macros with bpf_map__get_def()

2016-06-06T21:18:55+00:00

And for consistency, rename it to bpf_map__def(), leaving "get" for
reference counting.

Also make it return a const pointer, as suggested by Wang.
