Currently tracepoint events cannot be completed because they contain a
colon (:) character.  The colon is considered as a word separator when
bash completion is done - variable COMP_WORDBREAKS contains colon - so
if a word being completed contains a colon it can be a problem.

Recent versions of bash completion provide -n switch to
_get_comp_words_by_ref and __ltrim_colon_completions functions in order
to resolve this issue.  Copy the latter in case not exists.

For building perf without stack backtrace debug, we can set
NO_BACKTRACE=1 as a argument of make.  It then defines NO_BACKTRACE
macro for C code to do the proper handling.  However it usually used in
a negative semantics - e.g. #ifndef - so we saw double negations which
can be misleading.  Convert it to a positive form to make it more
readable and add _SUPPORT suffix for consistency.

We want to reduce the impact that each of the builtins has on perf as a
whole, so use the superclassing of perf_tool mechanizm to move its
config knobs to the stack, so that only if we use that tool, its impact
will be felt.

In this case is more about consistency, as the impact of this tool is

The newly added trace command requires an external audit library.

However it can cause a build error because it's not checked whether the
libaudit is installed on system:

    CC builtin-trace.o
  builtin-trace.c:7:22: fatal error: libaudit.h: No such file or directory
  compilation terminated.
  make: *** [builtin-trace.o] Error 1

So that the perf report won't lost the cpu utilization information.

For example, if there're two process that have same name.

  $ perf report --stdio --showcpuutilization -s pid
  [SNIP]
  #   Overhead       sys        us  Command:  Pid
  #   ........  ........  ........  .............
  #
        55.12%     0.01%    55.10%  noploop:28781
        44.88%     0.06%    44.83%  noploop:28782

Before:
  $ perf report --stdio --showcpuutilization -s comm
  [SNIP]
  #   Overhead       sys        us
  #   ........  ........  ........
  #
       100.00%     0.06%    44.83%

After:
  $ perf report --stdio --showcpuutilization -s comm
  [SNIP]
  #   Overhead       sys        us
  #   ........  ........  ........
  #
       100.00%     0.07%    99.93%
