Subject[PATCH 3/7] libperf: Move leader to perf_evsel::leader
Date
Moving evsel::leader to perf_evsel::leader, so we can move
the group interface to libperf.

Also adding several evsel helpers to ease up the transition:

struct evsel *evsel__leader(struct evsel *evsel);
- get leader evsel

bool evsel__has_leader(struct evsel *evsel, struct evsel *leader);
- true if evsel has leader as leader

bool evsel__is_leader(struct evsel *evsel);
- true if evsel is itw own leader

void evsel__set_leader(struct evsel *evsel, struct evsel *leader);
- set leader for evsel
