perf evsel: Introduce method to request IDs be used

2012-12-10T18:21:30Z

When mmaping multiple events we need to find the right evsel that matches an event in the ring buffer. For that we need to set the PERF_FORMAT_ID bit in perf_event_attr.read_format so that when we read the event fds we get that id to then hash it and be able later to use perf_evlist__id2evsel to find the right evsel. We also need to set the PERF_SAMPLE_ID bit in perf_event_attr.sample_type to ask for that id to be stashed in each sample, so that we can demux it. So add a perf_evsel__set_sample_id() method to do those two things in one operation.

perf test: Fixup error reporting in basic mmap test

2012-12-10T17:58:42Z

In two cases this test could detect an error, bail out but return zero. Fix it by reporting -1 for failure.
