perf config: Add stat.big-num support
Add support for new "stat.big-num" boolean option. This allows a user to set a default for "--no-big-num" for "perf stat" commands. -- $ perf config stat.big-num $ perf stat --event cycles /bin/true Performance counter stats for '/bin/true': 778,849 cycles [...] $ perf config stat.big-num=false $ perf config stat.big-num stat.big-num=false $ perf stat --event cycles /bin/true Performance counter stats for '/bin/true': 769622 cycles [...] -- There is an interaction with "--field-separator" that must be accommodated, such that specifying "--big-num --field-separator={x}" still reports an invalid combination of options. Documentation for perf-config and perf-stat updated.
