Add the following functions to the libtracecmd library:

 tracecmd_set_private() - set private data to tracecmd_input handle
 tracecmd_get_private() - get private data from tracecmd_input handle
 tracecmd_iterate_events() - iterate all events for a single buffer in a
                          trace.dat file (can filter on CPUs)
 tracecmd_iterate_events_multi() - iterate all events from multiple buffers
                          in a trace.dat file. (Does not filter on CPUs).
 tracecmd_filter_add() - Add a filter to a tracecmd_input handle that will
                          filter the iterator funtions.
 tracecmd_filter_match() - Will test a record against a given filter to see
                         if it matches or not.

As change trace-cmd to use these functions instead of doing the same thing
internally.


Steven Rostedt (Google) (9):
  tracecmd: Use make variable instead of if statement for zlib test
  tracecmd library: Add tracecmd_iterate_events()
  tracecmd utest: Add test to test using the libraries to read
  tracecmd library: Add tracecmd_iterate_events_multi()
  trace-cmd library: Allow callers to save private data in
    tracecmd_input handlers
  trace-cmd report: Use tracecmd_iterate_events_multi()
  trace-cmd library: Add filtering logic for iterating events
  trace-cmd report: Make filter arguments match their files
  trace-cmd report: Use library tracecmd_filter_*() logic
