perf session: Use evlist/evsel for managing perf.data attributes
So that we can reuse things like the id to attr lookup routine
(perf_evlist__id2evsel) that uses a hash table instead of the linear
lookup done in the older perf_header_attr routines, etc.
Also to make evsels/evlist more pervasive an API, simplyfing using the
emerging perf lib.
