perf record: Add switch-output size option argument
It's now possible to specify the threshold size for perf.data like:
$ perf record --switch-output=2G ...
Once it's reached, the current data are dumped in to the
perf.data.<timestamp> file and session does on.
$ perf record --switch-output=2G ...
[ perf record: dump data: Woken up 7244 times ]
[ perf record: Dump perf.data.2017010214093746 ]
...
The size is expected to be a number with appended unit character -
B/K/M/G.
