perf_counter tools: Prepare a small callchain framework
We plan to display the callchains depending on some user-configurable parameters. To gather the callchains stats from the recorded stream in a fast way, this patch introduces an ad hoc radix tree adapted for callchains and also a rbtree to sort these callchains once we have gathered every events from the stream.
