81f17c90f1 perf test: Add 'struct test *' to the test functions
This way we'll be able to pass more test specific parameters without
having to change this function signature.

Will be used by the upcoming 'shell tests', shell scripts that will
call perf tools and check if they work as expected, comparing its
effects on the system (think 'perf probe foo') the output produced, etc.

4208735d8d perf tools: Remove poll.h and wait.h from util.h
Not needed in this header, added to the places that need poll(), wait()
and a few other prototypes.

a43783aeec 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.

c8b5f2c96d tools: Introduce str_error_r()
The tools so far have been using the strerror_r() GNU variant, that
returns a string, be it the buffer passed or something else.

But that, besides being tricky in cases where we expect that the
function using strerror_r() returns the error formatted in a provided
buffer (we have to check if it returned something else and copy that
instead), breaks the build on systems not using glibc, like Alpine
Linux, where musl libc is used.

So, introduce yet another wrapper, str_error_r(), that has the GNU
interface, but uses the portable XSI variant of strerror_r(), so that
users rest asured that the provided buffer is used and it is what is
returned.

0b04b3dcdf perf evlist: Destructors should accept NULL
And do nothing, just like free(), to avoid having to test it in callers,
usually in error paths.

b31d660df3 perf tests: Add test to check for event times
This test creates software event 'cpu-clock' attaches it in several ways
and checks that enabled and running times match.

Committer notes:

Testing it:

  [acme@jouet linux]$ perf test -v times
  44: Test events times                                        :

  test child forked, pid 27170
  attaching to spawned child, enable on exec
    OK    : ena 307328, run 307328
  attaching to current thread as enabled
    OK    : ena 7826, run 7826
  attaching to current thread as disabled
    OK    : ena 738, run 738
  attaching to CPU 0 as enabled
    SKIP  : not enough rights
  attaching to CPU 0 as enabled
    SKIP  : not enough rights
  test child finished with -2
  ---- end ----
  Test events times: Skip
  [acme@jouet linux]$
