gprofng: 31123 improvements to hardware event implementation
Our hardware counter profiling is based on perf_event_open().
Our HWC tables are absent for new machines.
I have added HWC tables for the following events: PERF_TYPE_HARDWARE,
PERF_TYPE_SOFTWARE, PERF_TYPE_HW_CACHE. Other events require additional fixes.
Did a little cleaning: marked the symbols as static, used Stringbuilder,
created a function to read /proc/cpuinfo.
