perf trace/scripting: Add rwtop and sctop scripts A couple of scripts, one in Python and the other in Perl, that demonstrate 'live mode' tracing. For each, the output of the perf event stream is fed continuously to the script, which continuously aggregates the data and reports the current results every 3 seconds, or at the optionally specified interval. After the current results are displayed, the aggregations are cleared and the cycle begins anew. To run the scripts, simply pipe the output of the 'perf trace record' step as input to the corresponding 'perf trace report' step, using '-' as the filename to -o and -i: $ perf trace record sctop -o - \| perf trace report sctop -i - Also adds clear_term() utility functions to the Util.pm and Util.py utility modules, for use by any script to clear the screen.

perf trace scripting: remove system-wide param from shell scripts Including -a unconditionally when recording doesn't allow for the option of running scripts without it. Future patches will add add it back if needed at run-time.
