[PATCH v2 4/4] Make all print functions receive the fp argument, and opens a dump file in process_event.

From: yuzhoujian
Date: Tue Sep 26 2017 - 02:53:42 EST

This patch will make all print functions receive the fp argument, and opens
a dump file in process_event function

Changes since v1:
- modify the dump file name to <ORIGINAL PERF DATA FILE NAME>-script-dump-<EVENT NAME>.txt
ect. perf.data-script-dump-cycles.txt, perf.data-script-dump-cs.txt
- split the original patch(Make all those related functions receive the file pointer)
to two patches, and this is the second part of the original one.
