* libperf: Adopt simplified perf_evlist__open()/close() functions from tools/perfJiri Olsa2019-07-291-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | Add the following functions: perf_evlist__open() perf_evlist__close() It's a simplified version of perf's evlist__open() without the sampling id index calculations. We can try to merge it in the future when we need it in some new libperf user. Also adopt some helper evlist traversing macros. In the future we can remove them from util/evlist.h, but that requires also some other changes.
