perf tools: Move tracing_path stuff under same namespace
Renaming all functions touching tracing_path under same namespace. New
interface is:
char tracing_path[];
- tracing mount path
char tracing_events_path[];
- tracing mount/events path
void tracing_path_set(const char *mountpoint);
- setting directly tracing_path(_events), used by --debugfs-dir option
const char *tracing_path_mount(void);
- initial setup of tracing_(events)_path, called from perf.c
mounts debugfs/tracefs if needed and possible
char *get_tracing_file(const char *name);
void put_tracing_file(char *file);
- get/put tracing file path
