Summary from https://github.com/intel/perfmon/pull/68
 - Numerous uncore event additions and changes.
 - Description updates for core events XQ.FULL_CYCLES and MISC2_RETIRED.LFENCE.
 - Update ARITH.IDIV_ACTIVE counter mask.

This change also gets rid of uncore-other as a topic, derived from the
file name, breaking it apart in to more specific topics.

'perf sched latency' is incorrect to get process schedule latency when
it used 'sched:sched_wakeup' to analysis perf.data.

Because 'perf record' prefers to use 'sched:sched_waking' to
'sched:sched_wakeup' since commit d566a9c2 ("perf sched: Prefer
sched_waking event when it exists"). It's very reasonable to evaluate
process schedule latency.

Similarly, update sched latency/map/replay to use sched_waking events.

In __cmd_top(), perf_set_multithreaded() is used to enable
pthread_rwlock, thus down_read() and down_write () are not nops,
handling concurrency problems

Then 'perf top' uses perf_set_singlethreaded(), switching to the single
threaded phase, assuming that no thread concurrency will happen later.

However, a use after free problem could occur in the single threaded
phase, the concurrent procedure is this:

display_thread                              process_thread
--------------                              --------------
thread__comm_len
  -> thread__comm_str
    -> __thread__comm_str(thread)
                                            thread__delete
                                             -> comm__free
                                              -> comm_str__put
                                               -> zfree(&cs->str)
    -> thread->comm_len = strlen(comm);

Since in single thread phase, perf_singlethreaded is true, down_read()
and down_write() do nothing to avoid concurrency problems.

This patch moves the perf_set_singlethreaded() call to the function tail
to expand the multithreaded phase range, making display_thread() and
process_thread() concurrency safe.
