perf tools: Add trace-event object
Add trace-event object to keep together 'struct pevent' object with its loaded plugins with following interface: int trace_event__init(struct trace_event *t); - Initalizes 'struct pevent' object and loads plugins for it void trace_event__cleanup(struct trace_event *t); - Cleanups both 'struct pevent' and plugins Signed-off-by: Jiri Olsa <jolsa@redhat.com> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/r/1386076182-14484-10-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
