The bpftool interface stays the same, but now it's possible
to run it over BTF raw data, like:

  $ bpftool btf dump file /sys/kernel/btf/vmlinux
  [1] INT '(anon)' size=4 bits_offset=0 nr_bits=32 encoding=(none)
  [2] INT 'long unsigned int' size=8 bits_offset=0 nr_bits=64 encoding=(none)
  [3] CONST '(anon)' type_id=2

v3 changes:
 - fix title

v2 changes:
 - added is_btf_raw to find out which btf__parse_* function to call
 - changed labels and error propagation in btf__parse_raw
 - drop the err initialization, which is not needed under this change

Aw, this is v3? Looks like I replied to the older now, such confusion :)

yea, that went well.. sry, missed the v3 in title
