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. cc: Arun Sharma <arun@sharma-home.net> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Tom Zanussi <tzanussi@gmail.com> LKML-Reference: <new-submission> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
