As Namhyung Kim pointed, there are confused namings and descriptions of words
"cycle" and "clock" in mem-memset.c and mem-memcpy.c.

With the option "-c" (or "--clock", now renamed as "--cycle"), mem subsystem
measures cost of memset() and memcpy() with cpu-cycles event.

But current mem subsystem source code contains lots of confused variable
namings and descriptions with "clock" (e.g. the variable use_clock). This is a
very bad style because there is another software event named "cpu-clock". This
patch replaces wrong usage of "clock" to "cycle".

v2: modified Documentation/perf-bench.txt for the descriptions of
--cycle option

The internal pmu list was never used. With each perf_pmu__find() call
the pmu structure was created new by parsing sysfs. Beside this it
caused memory leaks. We now keep all pmus by adding them to the list.

Also, pmu_lookup() should return pmus that do not expose the format
specifier in sysfs.

We need a valid internal pmu list in a later patch to iterate over all
pmus that exist in the system.

When libtraceevent parses format fields, it assumes that array of 1 byte
is string but it's not always true. The kvm_emulate_insn contains 15 u8
array of insn that contains (binary) instructions. Thus when it's
printed, it'll have broken output like below:

  kvm_emulate_insn:     [FAILED TO PARSE] rip=3238197797 csbase=0 len=2 \
  insn=<89>P^]<B4>& flags=5 failed=0

With this patch:

  kvm_emulate_insn:     [FAILED TO PARSE] rip=3238197797 csbase=0 len=2 \
  insn=ARRAY[89, 10, 5d, c3, 8d, b4, 26, 00, 00, 00, 00, 55, 89, e5, 3e] flags=5 failed=0

Ingo reported that libtraceevent doesn't clean out dependency (.d) files
and it can cause a build error when the libgcc package upgraded:

 comet:~/tip/tools/perf> make -j
     SUBDIR ../lib/traceevent/
 make[1]: *** No rule to make target `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h',
  needed by `event-parse.o'.  Stop.
 make: *** [../lib/traceevent//libtraceevent.a] Error 2

So this patch makes the .d files depends on the source and header files
also, so that it can be re-generated as needed.

The pipeline:

generates the warning:
  Selected -g but no callchain data. Did you call 'perf record' without -g?

The problem is that the header data is not written to the pipe, so the
sample_type has not been available when perf_report__setup_sample_type
is called. For pipe mode, record dumps the sample type as part of the
synthesized events stream -- perf_event__synthesize_attrs(). Handle this
be detecting pipe mode and not doing early sanity checks on sample_type.

The pevent thing is per perf.data file, so I made it stop being static
and become a perf_session member, so tools processing perf.data files
use perf_session and _there_ we read the trace events description into
session->pevent and then change everywhere to stop using that single
global pevent variable and use the per session one.

Note that it _doesn't_ fall backs to trace__event_id, as we're not
interested at all in what is present in the
/sys/kernel/debug/tracing/events in the workstation doing the analysis,
just in what is in the perf.data file.

This patch also introduces perf_session__set_tracepoints_handlers that
is the perf perf.data/session way to associate handlers to tracepoint
events by resolving their IDs using the events descriptions stored in a
perf.data file. Make 'perf sched' use it.

The commit c410431c ("perf tools: Reconstruct event with modifiers
from perf_event_attr") added the line, but it's broken since it needs to
go up 3 directories to get to the kernel root directory, not 2.

However host gcc contains /usr/local/include in its search path, so that
it can find the perf_event.h in /usr/include. This why we didn't notice
the problem yet.  But when I tried to cross compile it appears like:

      CC util/evsel.o
  util/evsel.c:18:44: error: ../../include/linux/perf_event.h: No such file or directory
  make: *** [util/evsel.o] Error 1

Looking at the source, it isn't needed at all as evsel.h already
included the perf_event.h. So simply remove it would solve the problem.

From perf_evsel__hw_name, so that we can use it for the other kinds of
events (tracepoints, software, hw cache, etc).

To avoid having to resort to --stdio, that expands everything, instead
allow the user to go on expanding the relevant callchains and then press
'P' to print that view.

As the hists browser is used for both static (report) and dynamic (top)
views, it prints to a 'perf.hists.N' sequence, i.e. multiple snapshots
can be taken in report and top.

Define and use perf_gtk_eops to provide a GTK2 message dialog for error
reporting and a info_bar for warning.

As GtkInfoBar requires recent GTK+ libraries, provides a fallback
implementation using statusbar widget too.

The GtkInfoBar is a modern UI component to display messages without
bothering the main window. It'll be used for showing a warning message.

As the GtkInfoBar requires 2.18 (or newer) version of GTK+ library, add
availability check to Makefile too.

Add statusbar widget to display non-critical messages at the bottom of
the window. This can be used for showing a status change, warning or
help message.
