tools perf: Move from sane_ctype.h obtained from git to the Linux's original
We got the sane_ctype.h headers from git and kept using it so far, but
since that code originally came from the kernel sources to the git
sources, perhaps its better to just use the one in the kernel, so that
we can leverage tools/perf/check_headers.sh to be notified when our copy
gets out of sync, i.e. when fixes or goodies are added to the code we've
copied.
This will help with things like tools/lib/string.c where we want to have
more things in common with the kernel, such as strim(), skip_spaces(),
etc so as to go on removing the things that we have in tools/perf/util/
and instead using the code in the kernel, indirectly and removing things
like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements
are made to the original code.
Hopefully this also should help with reducing the difference of code
hosted in tools/ to the one in the kernel proper.

perf tools: Add 'evlist' control command
Add a new 'evlist' control command to display all the evlist events.
When it is received, perf will scan and print current evlist into perf
record terminal.
The interface string for control file is:
evlist [-v|-g|-F]
The syntax follows perf evlist command:
-F Show just the sample frequency used for each event.
-v Show all fields.
-g Show event group information.
Example session:
terminal 1:
# mkfifo control ack
# perf record --control=fifo:control,ack -e '{cycles,instructions}'
terminal 2:
# echo evlist > control
terminal 1:
cycles
instructions
dummy:HG
terminal 2:
# echo 'evlist -v' > control
terminal 1:
cycles: size: 120, { sample_period, sample_freq }: 4000, sample_type: \
IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, disabled: 1, inherit: 1, freq: 1, \
sample_id_all: 1, exclude_guest: 1
instructions: size: 120, config: 0x1, { sample_period, sample_freq }: 4000, \
sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, inherit: 1, freq: 1, \
sample_id_all: 1, exclude_guest: 1
dummy:HG: type: 1, size: 120, config: 0x9, { sample_period, sample_freq }: 4000, \
sample_type: IP|TID|TIME|ID|CPU|PERIOD, read_format: ID, inherit: 1, mmap: 1, \
comm: 1, freq: 1, task: 1, sample_id_all: 1, mmap2: 1, comm_exec: 1, ksymbol: 1, \
bpf_event: 1
terminal 2:
# echo 'evlist -g' > control
terminal 1:
{cycles,instructions}
dummy:HG
terminal 2:
# echo 'evlist -F' > control
terminal 1:
cycles: sample_freq=4000
instructions: sample_freq=4000
dummy:HG: sample_freq=4000
This new evlist command is handy to get real event names when
wildcards are used.
Adding evsel_fprintf.c object to python/perf.so build, because
it's now evlist.c dependency.
Adding PYTHON_PERF define for python/perf.so compilation, so we
can use it to compile in only evsel__fprintf from evsel_fprintf.c
object.

perf tools: Add missing object file to the python binding linkage list
In ac12f6764c50 ("perf tools: Implement branch_type event parameter") we
started using the parse_branch_str() function from one of the files used
in the python binding, which caused this entry in 'perf test' to fail:
# perf test -v python
16: Try 'import perf' in python, checking link problems :
--- start ---
test child forked, pid 16667
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /tmp/build/perf/python/perf.so: undefined symbol:
parse_branch_str
test child finished with -1
---- end ----
Try 'import perf' in python, checking link problems: FAILED!
#
I must've commited some mistake when running 'perf test' to send the
pull request for the perf-core-for-mingo-20161024 tag, to have let this
regression to pass, sigh.
Just add tools/perf/util/parse-branch-options.c and switch from using
ui__warning(), that is not available in the python binding, use
pr_warning() instead, which is good enough for this case.
Now:
# perf test python
16: Try 'import perf' in python, checking link problems : Ok

perf tools: Add missing files to build the python binding
Changeset 0f6a3015:
"perf tools: Support user regs and stack in sample parsing"
uses hweight_long in evsel.c, so we need to drag util/hweight.c
to the python binding.
Ditto for ee8dd3c:
"perf tools: Change strlist to use the new rblist"
where we need to add util/rblist.c.
Now twatch.py works again:

perf stat: Fix wrong skipping for per-die aggregation
Uncore becomes die-scope on Xeon Cascade Lake-AP and perf has supported
--per-die aggregation yet.
One issue is found in check_per_pkg() for uncore events running on AP
system. On cascade Lake-AP, we have:
S0-D0
S0-D1
S1-D0
S1-D1
But in check_per_pkg(), S0-D1 and S1-D1 are skipped because the mask
bits for S0 and S1 have been set for S0-D0 and S1-D0. It doesn't check
die_id. So the counting for S0-D1 and S1-D1 are set to zero. That's not
correct.
root@lkp-csl-2ap4 ~# ./perf stat -a -I 1000 -e llc_misses.mem_read --per-die -- sleep 5
1.001460963 S0-D0 1 1317376 Bytes llc_misses.mem_read

5.001479927 S1-D1 1 5496640 Bytes llc_misses.mem_read
From above output, we can see S0-D1 and S1-D1 don't report the interval
values, they are continued to grow. That's because check_per_pkg()
wrongly decides to use zero counts for S0-D1 and S1-D1.
So in check_per_pkg(), we should use hashmap(socket,die) to decide if
the cpu counts needs to skip. Only considering socket is not enough.
Now with this patch,
