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 cs -ag -- sleep 10
$perf script --per-event-dump
$ls
perf.data-script-dump-cycles.txt perf.data-script-dump-cs.txt
Without per-event-dump support, drawing flamegraphs for different events
would be a very troublesome thing. You can monitor only one event at a time
if you want to get flamegraphs for different events. Using this option, you
can get the trace output files named by the monitored events, and could draw
flamegraphs according to the event's name.
yuzhoujian (4):
Patch 1: Add a new element for the struct perf_tool, and add the
--per-event-dump option for perf script.
Patch 2: Add fp argument to print functions.
Patch 3: Replace printf with fprintf for all print functions.
Patch 4: Make all print functions receive the fp argument, and opens a dump
file in process_event.
changes since v1:
- Patch 1: Remove the set of script.tool.per_event_dump variable.
- Patch 2: Add the __maybe_unused attribute for the fp argument in the second patch.
- Patch 3: remove the fp_selection_helper function for setting the fp argument.
- Patch 2: split the original second patch(Makes all those related functions receive the FILE pointer) to two patches.
- Patch 4: modify the file name of per-event-dump to <ORIGINAL PERF DATA FILE NAME>-script-dump-<EVENT NAME>.txt

1.8.3.1
This patch will add a new bool variable per_event_dump to mark the per-event-dump option,
and add the OPT_BOOLEAN for per-event-dump in the perf_data_file struct.
Changes since v1:
- remove the set for script.tool.per_event_dump variable,since the OPT_BOOLEAN
will do the same thing.

1.8.3.1
This patch will add the fp argument to all the print functions so that they can use different
file pointer to print on the screen or dump in the file.
Changes since v1:
- add the __maybe_unused attribute for the fp argument in all the print functions,
because the fp is not used in this patch but needed in the later patches.
- split the original patch(Makes all those related functions receive the FILE
pointer) to two simple patches, and this is the first part.

1.8.3.1
This patch will replace printf with fprintf for all print functions in the
builtin-script in order to support the per-event-dump option.
Changes since v1:
- remove the fp_selection_helper function for setting the fp argument, and use
a local variable to do the same thing.
