<title>perf tools: Asprintf like functions to format integer filter expression</title>

  char *asprintf_expr_in_ints(const char *var, size_t nints, int *ints);
  char *asprintf_expr_not_in_ints(const char *var, size_t nints, int *ints);

Example of output formatted with those functions:

  # ./tp_filter 6 12 2015
  asprintf_expr_in_ints:     id == 6 || id == 12 || id == 2015
  asprintf_expr_not_in_ints: id != 6 &amp;&amp; id != 12 &amp;&amp; id != 2015
  #

It'll be used with, for instance, perf_evsel__set_filter_in_ints(), that
will be used in turn to ask the kernel to filter out all raw_syscalls:*
except for the ones specified by the user via:

 $ perf trace -e some,list,of,syscalls

<content type='text'>
This reverts commit 50e200f07948 ("perf tools: Default to cpu// for
events v5")

The fixup cannot handle the case that
new style format(which without //) mixed with
other different formats.

For example,
group events with new style format: {mem-stores,mem-loads}
some hardware event + new style event: cycles,mem-loads
Cache event + new style event: LLC-loads,mem-loads
Raw event + new style event:
cpu/event=0xc8,umask=0x08/,mem-loads
old style event and new stytle mixture: mem-stores,cpu/mem-loads/

That loop in there is both anti-idiomatic *and* completely pointless.
strtoll() is there for purpose; use it and compare what's left with
acceptable suffices.

When an event fails to parse and it's not in a new style format,
try to parse it again as a cpu event.

This allows to use sysfs exported events directly without //, so you can use

perf record -e mem-loads ...

instead of

perf record -e cpu/mem-loads/
