which analysed the mutex6 test case of this test, and concluded
that it was useless, nonsense, and broken (the whole test is just a
race - not even really using or testing mutexes), let it be henceforth
forever gone.

Make the mutex6 test (which fails every know and then, but too rarely
to actually debug it) print some debug info when failing.

Avoid using an uninitialized mutex.

reenable mutex2 and mutex3 on powerpc now that PR 44387 is fixed.

Merge and fix the timed mutex tests to use absolute time.
NB: the new tests are broken?

Add new test t_timedmutex

This test is a clone on t_mutex with additional two tests for timed-mutex
specific block.

All simple-mutex (not with the timed property according to the C11 wording)
specific tests are covered by pthread_mutex_timedlock(3) with parameter
ts_lengthy of sufficiently large tv_sec value (right now UINT16_MAX). If,
a test will hang, it won't wait UINT16_MAX seconds, but will be terminated
within the default timeout for ATF tests (right now 300 [sec] in my
NetBSD/amd64 setup).

This test was inspired by a classic selflock test failure of
pthread_mutex_timedlock(3) of the following form:

#include <assert.h>
#include <errno.h>
#include <pthread.h>
#include <stdio.h>
#include <time.h>

int main(int argc, char **argv)
{
pthread_mutex_t mtx;
struct timespec ts;

ts.tv_sec = 0;
ts.tv_nsec = 1000;
printf("ts{.tv_sec = %d, .tv_nsec=%ld}\n", ts.tv_sec, ts.tv_nsec);
fflush(stdout);

printf("mtx_init\n");
assert(pthread_mutex_init(&mtx, NULL) == 0);

printf("mtx_lock\n");
assert(pthread_mutex_lock(&mtx) == 0);

printf("mtx_timedlock\n");
assert(pthread_mutex_timedlock(&mtx, &ts) == ETIMEDOUT);

printf("mtx_unlock\n");
assert(pthread_mutex_unlock(&mtx) == 0);

printf("mtx_destroy\n");
assert(pthread_mutex_destroy(&mtx) == 0);

return 0;
}

Current NetBSD implementation wrongly hangs on this test.

The issue was detected during development of the C11 portable threads.

My local tests in chroot presents that the are further issues:

t_timedmutex (21/25): 10 test cases
mutex1: [0.001142s] Failed: /usr/src/tests/lib/libpthread/t_timedmutex.c:75: *param != 20

timedmutex2: [301.123081s] Failed: Test case timed out after 300 seconds
[623.990659s]

I'm also receiveing the same failure in the mutex6 test in t_mutex, so
there might be a false positives due to local chroot(8) issues.

PR misc/49356 remove unnecessary references to atf-c/config.h

The function included via this header is not used and is removed in
later versions of atf, so let us avoid it.

Use compiler builtins instead of atf_arch and atf_machine.

The atf_arch and atf_machine configuration variables were removed from
atf-0.19 without me realizing that some tests were querying them directly.

Instead of reintroducing those variables, just rely on compiler builtins
as many other tests already do.

Should fix PR bin/48582.

The mutex3 test is supposed to use a static initializer so that it differs
to the mutex2 test. This detail was lost during the atfification of these
tests.

I think that this, together with the previous conversion of librt, obsoletes
the tests in the semaphore/ directory. Will investigate later.
