On POWER, the 'perf format parsing' test always fails.

Looks like it is because memset() is being passed number of longs rather
than number of bytes. It is interesting that the test always passes on
my x86 box.

With this patch, the test passes on POWER and continues to pass on x86.

When make runs it tries to update the Makefile rules by reading all of
included Makefiles.  During the perf build it checks PERF-VERSION-FILE
to get the current version number.  But it triggers Makefile update so
that make runs again with the update Makefile and, in turn, users will
see duplicate CHK message on the second path.

Running make with -d option for debugging tells me this:

Actually PERF-VERSION-FILE is used only for perf.c to #define
PERF_VERSION macro.  So make it like a C header file and include it
during compiling the perf.c file will remove the need of being
included into Makefile.  Hench no need to update the Makefile and no
CHK lines anymore.

Current perf report gets segmentation fault when a branch stack specific
sort key is provided by --sort option to a perf.data file which contains
no branch infomation.  It's because those sort keys reference branch
info of a hist entry unconditionally.  Maybe we can change it checks
whether such branch info is valid or not.  But if the branch stacks are
not recorded, it'd be nop.  Thus it'd be better to make those keys are
unselectable.

This patch separates those keys to a different dimension array, so that
if user passes such a key to a file which has no branch stack will get
following message rather than a segfault.

  Error: Invalid --sort key: `symbol_from'

The "pid" sort key prints "Command: Pid" output but it's misaligned.
It's because of the offset of 6 was added to the column length during
the calculation in order to reserve an space for Pid part but it isn't
honored when printed.  The output before this patch was like this:

  # Overhead  Command:  Pid      Shared Object
  # ........  .............  .................
  #
      99.70%        noploop:17814  noploop

perf bench prints header message for bench suite before starting the
benchmark.  However if the stdout is redirected to a file and bench
suite forks child processes this (and possibly other debugging
messages too) will be repeated multiple times.

  $ perf bench sched messaging
  # Running sched/messaging benchmark...
  # 20 sender and receiver processes per group
  # 10 groups == 400 processes run

       Total time: 0.100 [sec]

  $ perf bench sched messaging > result.txt
  $ wc -l result.txt
  391

In this file, there were so many "Running sched/messaging benchmark..."
lines.  This was because stdout is converted to fully-buffered due to
the redirection and inherited child processes.  Other lines are printed
after reaping all those tasks.

So fix it by flushing stdout before starting bench suites.

The elf.h header file is used for NO_LIBELF build too so it should be
included anyway.  Also remove duplicated include of the header file in
symbol-*.c.  This patch fixes following build error on NO_LIBELF build:

According to Documentation/Changes, the kernel should be buildable with
GNU make 3.80+. tools/perf/config/utilities.mak contains the "$(or"
construct, which requires make 3.81.  This causes "make" to fail on
systems with GNU make 3.80.

Replace "$(or" with an equivalent "$(if" expression, to restore backward
compatibility. Also fix an issue where _get_attempt was called with only
one argument. This prevented the error message from printing the name of
the variable that can be used to fix the problem.

The ui__error/warning functions use gtk infobar or statusbar and pr_*
functions use statusbar too.  But after perf gtk context created but
those infobar and/or statusbar not yet set up, calling one of those
functions will get a segment fault.

Although current code has no problem, move these setting as early as
possible so that it can prevent the segfault from future change.
