In order to be able to lazily compute aliases/events for a PMU, move the struct perf_pmu_alias into pmu.c. Add perf_pmu__find_event and perf_pmu__for_each_event that take a callback that is called for the found event or for each event. The layout of struct pmu and the event/alias list is unchanged but the API is altered so that aliases are no longer directly accessed, allowing for later changes.
