[PATCH v2 0/3] perf util: bpf perf improvements

[Song Liu]

This patches set improves bpf_perf (perf-stat --bpf-counter) by
  1) exposing key definitions to a libperf header;
  2) adding compatibility check for perf_attr_map;
  3) introducing config stat.bpf-counter-events.

Changes v1 => v2:
1. Separte 2/3 from 1/3. (Jiri)
2. Rename bperf.h to bpf_perf.h. (Jiri)
3. Other small fixes/optimizations. (Jiri)

Song Liu (3):
  perf util: move bpf_perf definitions to a libperf header
  perf bpf: check perf_attr_map is compatible with the perf binary
  perf-stat: introduce config stat.bpf-counter-events
