Introduce a new option to print trace output to files named by the 
monitored events and update perf-script documentation accordingly.

Shown below is output of perf script command with the newly introduced
option.

        $perf record -e cycles -e context-switches -ag -- sleep 10
        $perf script --per-event-dump
        $ls /
        cycles.stacks context-switches.stacks

Without per-event-dump support, drawing flamegraphs for different events
is really hard. You can only monitor one event at a time for perf record.
Using this option, we can get the trace output files named by the monitored
events, and could draw flamegraphs according to the event's name.

yuzhoujian (3):
  Add a new element for the struct perf_tool, and add the     
    --per-event-dump option for perf script
  Makes all those related functions receive the FILE pointer
  Replace printf with fprintf for all the output functions
