Wang Nan ecfd7a9c04 perf record: Add '--timestamp-filename' option to append timestamp to output file name ...

This option appends current timestamp to the output file name.

For example:

  # perf record -a --timestamp-filename
  ^C[ perf record: Woken up 1 times to write data ]
  [ perf record: Dump perf.data.2015122622265847 ]
  [ perf record: Captured and wrote 0.742 MB perf.data.<timestamp> (90 samples) ]
  # ls
  perf.data.201512262226584

The timestamp will be useful for identifying each perf.data after the
'perf record' support for generating multiple output files gets
introduced.
