libperf: Add perf_thread_map__get()/perf_thread_map__put()

Move the following functions:

  thread_map__get()
  thread_map__put()
  thread_map__comm()

to libperf with the following names:

  perf_thread_map__get()
  perf_thread_map__put()
  perf_thread_map__comm()

Add the perf_thread_map__comm() function for it to work/compile.
