This patch extends the current argument list in case of events by
- IP / addr of the event. Currently only the function name is passed.
- seconds and ns as the timestamp. Split into two value to stay close to
what the trace handler passes.
- the pid of the proccess
I added a common_ prefix to stay close to the naming of the "trace"
handler. Currently I don't mind dropping it since "comm" isn't named
"common_comm". Any suggestions?
All items I added here are already exposed by the generic output i.e.
"perf script"
