I'd like to be able to test narrow and wide string interfaces, with
the narrow string tests using TEST_COMPARE_STRING and the wide string
tests using something analogous (possibly generated using macros from
a common test template for both the narrow and wide string tests where
appropriate).
Add such a TEST_COMPARE_STRING_WIDE, along with functions
support_quote_blob_wide and support_test_compare_string_wide that it
builds on. Those functions are built using macros from common
templates shared by the narrow and wide string implementations, though
I didn't do that for the tests of test functions. In
support_quote_blob_wide, I chose to use the \x{} delimited escape
sequence syntax proposed for C2X in N2785, rather than e.g. trying to
generate the end of a string and the start of a new string when
ambiguity would result from undelimited \x (when the next character
after such an escape sequence is valid hex) or forcing an escape
sequence to be used for the next character in the case of such
ambiguity.
Tested for x86_64.

The fd validity check in open_dev_null checks if fd > 0, which would
lead to a leaked fd if it is == 0.

Some kernel versions (observed with kernel 5.14 and earlier) can list
"0" entries in /proc/self/task. This happens when a thread exits
while the task list is being constructed. Treat this entry as not
present, like the proposed kernel patch does:
[PATCH] procfs: Do not list TID 0 in /proc/<pid>/task

When testing nptl/tst-pthread-attr-affinity-fail fails with:
error: xsysconf.c:33: sysconf (83): Cannot allocate memory
error: 1 test failures
This happens as xsysconf checks the errno after running sysconf.
Internally the sysconf request for _SC_NPROCESSORS_CONF on linux
allocates memory. But there is a problem, even though malloc succeeds
errno is getting set to ENOMEM.
POSIX allows successful calls to clobber errno. So xsysconf just
checking errno is wrong. Fix xsysconf by only failing if we have an
error result and errno is set.

The recent change to use __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64 to avoid

Replace _SC_MINSIGSTKSZ with _SC_SIGSTKSZ since sysconf (_SC_MINSIGSTKSZ)

The code to allocate a stack from xsigstack is refactored so it can
be more generic. The new support_stack_alloc() also set PROT_EXEC
if DEFAULT_STACK_PERMS has PF_X. This is required on some
architectures (hppa for instance) and trying to access the rtld
global from testsuite will require more intrusive refactoring
in the ldsodefs.h header.
Checked on x86_64-linux-gnu and i686-linux-gnu. I also ran
tst-xsigstack on both hppa and ia64.

Add a new function support_capture_subprogram_self_sgid that spawns an
sgid child of the running program with its own image and returns the
exit code of the child process. This functionality is used by at
least three tests in the testsuite at the moment, so it makes sense to
consolidate.
There is also a new function support_subprogram_wait which should
provide simple system() like functionality that does not set up file
actions. This is useful in cases where only the return code of the
spawned subprocess is interesting.
This patch also ports tst-secure-getenv to this new function. A
subsequent patch will port other tests. This also brings an important
change to tst-secure-getenv behaviour. Now instead of succeeding, the
test fails as UNSUPPORTED if it is unable to spawn a setgid child,
which is how it should have been in the first place.

Both new tests io/tst-stat and io/tst-stat-lfs (_FILE_OFFSET_BITS=64)
are comparing the nanosecond fields with the statx result. Unfortunately
on s390(31bit) those fields are always zero if old KABI with non-LFS
support is used. With _FILE_OFFSET_BITS=64 stat is using statx internally.
As suggested by Adhemerval this patch disables the nanosecond check for
s390(31bit).

Some Linux filesystems might not fully support 64 bit timestamps [1],
which make some Linux specific tests to fail when they check for the
functionality.
This patch adds a new libsupport function, support_path_support_time64,
that returns whether the target file supports or not 64 bit timestamps.
The support is checked by issuing a utimensat and verifying both the
last access and last modification time against a statx call.
The tests that might fail are also adjusted to check the file support
as well:

There's a small chance that a fresh checkout will result in some of
the test-specific container files will have the same timestamp and
size, which breaks the rsync logic in test-container, resulting in
tests running with the wrong support files.
This patch changes the rsync logic to always copy the test-specific
files, which normally would always be copied anyway. The rsync logic
for the testroot itself is unchanged.

The xclock_settime is a wrapper function on the clock_settime syscall
to be used in the test code.
It checks if the GLIBC_TEST_ALLOW_TIME_SETTING env variable is defined
in the environment in which test is executed. If it is not - the test
ends as unsupported. Otherwise, the clock-settime is executed and return
value is assessed.

For configurations with cross-compiling equal to 'maybe' or 'no',
ldconfig will not run and thus the ld.so.cache will not be created
on the container testroot.pristine.
This lead to failures on both tst-glibc-hwcaps-prepend-cache and
tst-ldconfig-ld_so_conf-update on environments where the same
compiler can be used to build different ABIs (powerpc and x86 for
instance).
