Ian Rogers 605fd1c8b7 perf python: Port rwtop from Perl to perf module ... Replace the legacy Perl script rwtop.pl with a standalone Python script in tools/perf/python/rwtop.py using the perf Python module. Improvements compared to the legacy Perl script: - Remove the dependency on libperl and Perf::Trace::Util. - Support both offline perf.data files (via perf.session) and live recording (via LiveSession with --live), driving periodic interval summaries from event timestamps rather than wall-clock SIGALRM timers so both live and offline runs produce deterministic output. - Convert unsigned 32-bit and 64-bit error return values (0xfffff000..0xffffffff and >= 0x8000000000000000) to negative errnos so failed read/write syscalls are recorded in the error table rather than inflating bytes_read / bytes_written. - Sanitize non-printable characters in /proc/<pid>/comm to prevent terminal control sequence injection. Add a shell test (test_rwtop_python.sh) to verify the standalone script.
