While opening a trace event counter, every events are saved in
the trace.info file. But we only want to save the
specifications of the events we are using.

Add util/trace-event-info.c which handles ftrace file IO from
debugfs and provides general helpers to fetch/save ftrace
events informations.
This file is a rename of the trace-cmd.c file from the
trace-cmd tools, written by Steven Rostedt and Josh Triplett,
originated from the git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This is a perf tools integration.
For now, ftrace events information is saved in a separate file
than the standard perf.data
