Masami Hiramatsu d3b63d7ae0 perf probe: Fix a bug that --line range can be overflow ... Since line_finder.lno_s/e are signed int but line_range.start/end are unsigned int, it is possible to be overflow when converting line_range->start/end to line_finder->lno_s/e. This changes line_range.start/end and line_list.line to signed int and adds overflow checks when setting line_finder.lno_s/e.
