perf/core: Prepare perf_event.h for new types: 'perf_kprobe' and 'perf_uprobe' Two new perf types, perf_kprobe and perf_uprobe, will be added to allow creating [k,u]probe with perf_event_open. These [k,u]probe are associated with the file decriptor created by perf_event_open(), thus are easy to clean when the file descriptor is destroyed. kprobe_func and uprobe_path are added to union config1 for pointers to function name for kprobe or binary path for uprobe. kprobe_addr and probe_offset are added to union config2 for kernel address (when kprobe_func is NULL), or [k,u]probe offset.
