Wang Nan 10bf358a1b perf tools: Enable config raw and numeric events ...

This patch allows setting config terms for raw and numeric events.
For example:

  # perf stat -e cycles/name=cyc/ ls
  ...
  1821108      cyc
  ...

  # perf stat -e r6530160/name=event/ ls
  ...
  1103195      event
  ...

  # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1
  ...
  # perf report --stdio
  ...
  # Samples: 124  of event 'cycles'
  46.61%     0.00%  swapper        [kernel.vmlinux]            [k] cpu_startup_entry
  41.26%     0.00%  swapper        [kernel.vmlinux]            [k] start_secondary
  ...
  # Samples: 91  of event 'evtx'
  ...
  93.76%     0.00%  swapper      [kernel.vmlinux]            [k] cpu_startup_entry
          |
          ---cpu_startup_entry
             |
             |--66.63%--call_cpuidle
             |          cpuidle_enter
             |          |
  ...

3 test cases are introduced to test config terms for symbol, raw and
numeric events.

Committer note:

Further testing shows that we can retrieve the event name using 'perf
evlist -v' and looking at the 'config' perf_event_attr field, i.e.:

  # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 1.724 MB perf.data (2076 samples) ]
  # perf evlist
  cycles
  evtx
  # perf evlist -v
  cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|CPU|PERIOD|IDENTIFIER, read_format: ID, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, task: 1, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1
evtx: type: 4, size: 112, config: 0x6530160, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|CALLCHAIN|CPU|PERIOD|IDENTIFIER, read_format: ID, disabled: 1, inherit: 1, freq: 1, sample_id_all: 1, exclude_guest: 1
