Subject: 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.

Subject: perf tools: Remove support for command aliases

This came from 'git', but isn't documented anywhere in
tools/perf/Documentation/, looks like baggage we can do without, ditch
it.

Subject: 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.

Subject: perf tools: Add signal.h to places using its definitions

And remove it from util.h, disentangling it a bit more.

Subject: perf tools: Remove stale prototypes from builtin.h

Some, like prune_packed_objects() are clearly git specific, others
don't have implementations and some are used in just one place, make
them static.

Not needed in this header, added to the places that need FILE,
putchar(), access() and a few other prototypes.

From 5ab8c689f7c0c97e98b8014b7f0ede386bef5aaf Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Tue, 25 Apr 2017 15:30:47 -0300
Subject: 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.
