perf/core improvements and fixes:

- Do event name substring search as last resort in 'perf list'.
  (Arnaldo Carvalho de Melo)

  E.g.:

   # perf list clock

   List of pre-defined events (to be used in -e):

     cpu-clock                                          [Software event]
     task-clock                                         [Software event]

     uncore_cbox_0/clockticks/                          [Kernel PMU event]
     uncore_cbox_1/clockticks/                          [Kernel PMU event]

     kvm:kvm_pvclock_update                             [Tracepoint event]
     kvm:kvm_update_master_clock                        [Tracepoint event]
     power:clock_disable                                [Tracepoint event]
     power:clock_enable                                 [Tracepoint event]
     power:clock_set_rate                               [Tracepoint event]
     syscalls:sys_enter_clock_adjtime                   [Tracepoint event]

     syscalls:sys_exit_clock_settime                    [Tracepoint event]

- Reduce min 'perf stat --interval-print/-I' to 10ms (Kan Liang)

  perf stat --interval in action:

  # perf stat -e cycles -I 50 -a usleep $((200 * 1000))
  print interval < 100ms. The overhead percentage could be high in some cases. Please proceed with caution.
  #   time                    counts unit events
      0.050233636         48,240,396      cycles
      0.100557098         35,492,594      cycles
      0.150804687         39,295,112      cycles

- Allow for max_stack greater than PERF_MAX_STACK_DEPTH, as when
  synthesizing callchains from Intel PT data (Adrian Hunter)

- Allow probing on kmodules without DWARF (Masami Hiramatsu)

- Fix a segfault when processing a perf.data file with callchains using
  "perf report --call-graph none" (Namhyung Kim)

- Fix unresolved COMMs in 'perf top' when -s comm is used (Namhyung Kim)

- Register idle thread in 'perf top' (Namhyung Kim)

- Change 'record.samples' type to unsigned long long, fixing output of
  number of samples in 32-bit architectures (Yang Shi)
