Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

perf record:

Stephane Eranian:

- Fix priv level with branch sampling for paranoid=2, i.e. the kernel checks
if perf_event_attr_attr.exclude_hv is set in addition to .exclude_kernel,
so reset both to zero.

Arnaldo Carvalho de Melo:

- Don't warn about not being able to read kernel maps (kallsyms, etc) when
kernel samples aren't being collected.

perf list:

Kim Phillips:

- Allow plurals for metric, metricgroup., i.e.:

$ perf list metrics

was showing nothing, which is very confusing, make it work like:

$ perf stat metric

perf stat:

Andi Kleen:

- Free memory access/leaks detected via valgrind, related to metrics.

Libraries:

libperf:

Jiri Olsa:

- Move more stuff from tools/perf, this time a first stab at moving perf_mmap
methods.

libtracevent:

Steven Rostedt (VMware):

- Round up in tep_print_event() time precision.

Tzvetomir Stoyanov (VMware):

- Man pages for event print and related and plugins APIs.

- Move traceevent plugins in its own subdirectory.

Feature detection:

Thomas Richter:

- Add detection of java-11-openjdk-devel package, in addition to the older
versions supported.

Architecture specific:

S/390:

Thomas Richter (2):

- Include JVMTI support for s390

Vendor events:

AMD:

Kim Phillips:

- Add L3 cache events for Family 17h.

- Remove redundant '['.

PowerPC:

Mamatha Inamdar:

- Remove P8 HW events which are not supported.

Cleanups:

Arnaldo Carvalho de Melo:

- Remove needless headers, add needed ones, move things around to reduce the
headers dependency tree, speeding up builds by not doing needless compiles
when unrelated stuff gets changed.

- Ditch unused code that was dragging headers.

perf tools: No need to include internal/lib.h from util/util.h

That was done just to have users of writen() and readn(), that before
had their prototypes in util/util.h to get it without having to add an
include for internal/lib.h, but the right way is to add it and by now
all places already do it.

Fix a fallout were readlink() was used but unistd.h was being obtained
by luck thru util.h -> internal/lib.h, now to check why unistd.h is
being included there...
