perf scripts python: intel-pt-events.py: Fix printing of switch events

2021-12-28T20:26:25+00:00

The intel-pt-events.py script displays only the last of consecutive switch
statements but that may not be the last switch event for the CPU. Fix by
keeping a dictionary of last context switch keyed by CPU, and make it
possible to see all switch events by adding option --all-switch-events.

perf scripting python: Assign perf_script_context

2021-06-01T13:03:33+00:00

The scripting_context pointer itself does not change and nor does it need
to. Put it directly into the script as a variable at the start so it does
not have to be passed on each call into the script.
