neglected to do a final increment of the array pointer.  The result is
that the following parsing might start at the wrong place.

Currently we have symbol_conf.exclude_other being set as true every time
so the -x/--exclude-other has nothing to do.

Also we have no way to see the data with symbol_conf.exclude_other being
false which is useful sometimes.

Fixing it by making symbol_conf.exclude_other false by default.

1) Example without -x option:

  $ perf report -i perf.data.delete -p perf_session__delete -s parent

  +  99.91%  [other]
  +   0.08%  perf_session__delete
  +   0.00%  perf_session__delete_dead_threads
  +   0.00%  perf_session__delete_threads

2) Example with -x option:

  $ ./perf report -i perf.data.delete -p perf_session__delete -s parent -x

  +  96.22%  perf_session__delete
  +   1.89%  perf_session__delete_dead_threads
  +   1.89%  perf_session__delete_threads

In Example 1) we get the sorted out data together with the rest
"[other]". This could help us estimate how much time we spent in the
sorted data.

In Example 2) the total is just the sorted data.

When perf tries to start a workload, it relies on a pipe which the
workload was blocked for reading.  After closing the pipe on the parent,
the workload (child) can start the actual work via exec().

However, if another process was forked after creating a workload, this
mechanism cannot work since the other process (child) also inherits the
pipe, so that closing the pipe in parent cannot unblock the workload.
Fix it by using explicit write call can then closing it.

For similar reason, the pipe fd on parent should be marked as CLOEXEC so
that it can be closed after another child exec'ed.

This patch fixes a problem with perf stat whereby on termination it may
send a SIGTERM signal to random processes on systems with high PID
recycling. I got some actual bug reports on this.

There is race between the SIGCHLD and sig_atexit() handlers.  This patch
addresses this problem by clearing child_pid in the SIGCHLD handler.

Building perf for android fails because it can't find the definition of
struct winsize.

This definition is in termios.h, so I add this header to util.h to solve

builtin-top.c to util.c, but missed to move termios.h header.

Consider tweaking /proc/sys/kernel/perf_event_paranoid:
 -1 - Not paranoid at all
  0 - Disallow raw tracepoint access for unpriv

We have a one of the event open fallback case in __perf_evsel__open
where we zero exclude_guest|exclude_host fields.

This means there's no way for attr tests to find out what's the right
value for those fields, so we need to check for both 0 and 1. Luckily we
still have other event parsing tests for those fields.

The sample type for '-d' option is changed, because of the memory
profiling patches from Stephane. The '-d' now adds PERF_SAMPLE_DATA_SRC
sample_type.
