Arnaldo Carvalho de Melo 5ab8c689f7 perf tools: Move event prototypes from util.h to event.h
More needs to be done to have the actual functions and variables in a
smaller .c file that can then be included in the python binding,
avoiding dragging more stuff into it.

Arnaldo Carvalho de Melo 391e420600 perf tools: Include sys/param.h where needed
As it is going away from util.h, where it is not needed.

This is mostly for things like MAXPATHLEN, MAX() and MIN(), these later
two probably should go away in favor of its kernel sources replacements.

Arnaldo Carvalho de Melo a43783aeec perf tools: Include errno.h where needed
Removing it from util.h, part of an effort to disentangle the includes
hell, that makes changes to util.h or something included by it to cause
a complete rebuild of the tools.

Arnaldo Carvalho de Melo b0ad8ea664 perf tools: Remove unused 'prefix' from builtin functions
We got it from the git sources but never used it for anything, with the
place where this would be somehow used remaining:

  static int run_builtin(struct cmd_struct *p, int argc, const char **argv)
  {
	prefix = NULL;
	if (p->option & RUN_SETUP)
		prefix = NULL; /* setup_perf_directory(); */

Ditch it.

Namhyung Kim 1936feae54 perf c2c: Fix display bug when using pipe
Currently 'perf c2c report' determines display mode using the --stdio
option, but it could be a problem if stdout is not a tty since
setup_browser falls back to stdio in this case.

But perf c2c didn't know this and tried to use TUI browser anyway.  It
should check "use_browser" variable instead.

For example, the following command showed nothing and broke terminal
setting.  Now it's fixed..

  $ perf c2c report | head
  =================================================
              Trace Event Information
  =================================================
    Total records                     :        136
    Locked Load/Store Operations      :          6
    Load Operations                   :         62
    Loads - uncacheable               :          0
    Loads - IO                        :          1
    Loads - Miss                      :          7
    Loads - no mapping                :          2

Committer notes:

When trying it without a proper perf.data file it results in a stuck
terminal, just as Namhyung reported above:

  [acme@jouet ~]$ perf c2c report | head
  WARNING: no sample cpu value[acme@jouet ~]$

One has to kill it from some other xterm. Confirm that this patch fixes
it:

After:

  $ perf c2c report | head

              Trace Event Information

Jiri Olsa d940baccc9 perf c2c report: Display total HITMs on default
Currently we display the cacheline list sorted on remote HITMs by
default.

The problem is that they might not be always counted and 'perf c2c
report' displays an empty output. Thus it's more convenient to display
and sort the cacheline list based on the total of HITMs and have the
best change to see data in the default report run.

Jiri Olsa fc9c630e8e perf c2c report: Allow to set cacheline sort fields
Allowing user to configure the way the single cacheline
data are sorted after being sorted by offset.

Adding 'c' option to specify sorting fields for single cacheline:

    -c, --coalesce <coalesce fields>
                          coalesce fields: pid,tid,iaddr,dso

It's allowed to use following combination of fields:
  pid   - process pid
  tid   - process tid
  iaddr - code address
  dso   - shared object
