ffe59788e6 perf test: Add test case for pmu event new style format
Add test case in automated tests suite. It checks not only the two types
of pmu event stytle formats "pmu_event_name" and "cpu/pmu_event_name/",
but also the different formats mixtures which are more likely to trigger
parse issue.

The patch set including this one has been tested by the perf automated
test:

   ./perf test parse -v"

On haswell, ivybridge and Romley platform.

The patch set also has been tested on haswell by the following script.

Note: please make sure that your test system support TSX and
L1-dcache-loads events. Otherwise, you may want to change the events to
other pmu events.

  [lk@localhost ~]$ cat perf_style_test.sh
  # hardware events + kernel pmu event with different style
  perf stat -x, -e cycles,mem-stores,tx-start sleep 2
  perf stat -x, -e cpu-cycles,cycles-ct,cycles-t sleep 2
  perf stat -x, -e cycles,cpu/cycles-ct/,cpu/cycles-t/ sleep 2
  perf stat -x, -e instructions,cpu/tx-start/ sleep 2
  perf stat -x, -e '{cycles,tx-start}' sleep 2
  perf stat -x, -e '{cycles,cpu/tx-start/}' sleep 2

  # HW Cache event + kernel pmu event with different style
  perf stat -x, -e L1-dcache-loads,cpu/mem-stores/,tx-start sleep 2
  perf stat -x, -e L1-dcache-loads,mem-stores,cpu/tx-start/ sleep 2
  perf stat -x, -e '{L1-dcache-loads,mem-stores}' sleep 2
  perf stat -x, -e '{L1-dcache-loads,cpu/tx-start/}' sleep 2

  # Raw event + kernel pmu event with different style:
  perf stat -x, -e cpu/event=0xc0,umask=0x00/,mem-loads,cpu/mem-stores/ sleep 2
  perf stat -x, -e cpu/event=0xc0,umask=0x00/,tx-start,cpu/el-start/ sleep 2
  perf stat -x, -e '{cpu/event=0xc0,umask=0x00/,tx-start}' sleep 2

615b8f99f7 perf tests: Add numeric identifier to evlist_test
In tests/parse-events.c test cases are declared in evlist_test[]
arrays. Elements of arrays are initialized in following pattern:
	[i] = {
 		.name  = ...,
 		.check = ...,
 	},

When perf-test is running with '-v' option, 'i' variable will be
printed for every existing test.

However, we can't add any arch specific tests inside #ifdefs, because it
will create collision between the element number inside #ifdef and the
next one outside.

This patch adds 'id' field in evlist_test, uses it as a test
identifier and removes explicit numbering of array elements. This helps
to number tests with gaps.

553873e1df tools/: Convert to new topic libraries
Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.

For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.

acme:

"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.

But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."

Fixup documentation cleaning target while at it.

cf38fadade perf fs: Rename NAME_find_mountpoint() to NAME__mountpoint()
Shorten it, "finding" it is an implementation detail, what callers want
is the pathname, not to ask for it to _always_ do the lookup.

And the existing implementation already caches it, i.e. it doesn't
"finds" it on every call.

823254edc6 perf evsel: Convert to _is_group_leader method
Convert perf_evsel__is_group_member to perf_evsel__is_group_leader.
This is because the most usecases are using negative form to check
whether the given evsel is a leader or not and it's IMHO somewhat
ambiguous - leader also *is* a member of the group.

07ac002f2f perf evsel: Introduce is_group_member method
To clarify what is being tested, instead of assuming that evsel->leader
== NULL means either an 'isolated' evsel or a 'group leader'.
