e74b61c09a Disable -Wstringop-overread for some string tests
Similarly to Maciej's changes to fix the build of rawmemchr in the
presence of GCC 11's -Wstringop-overread, also disable that option in
two string function tests that have similar warnings and other string
function warnings already disabled.

Tested with build-many-glibcs.py for aarch64-linux-gnu and
arm-linux-gnueabi that it fixes building the glibc testsuite.

7b51d9f69e C11 threads: Fix inaccuracies in testsuite
- tst-mtx-recursive.c: mtx_init fails to use mtx_plain.  Per C11
  specs, using mtx_recursive alone is not supported.  This isn't
  catched because mtx_plain is defined as 0.

- tst-thrd-sleep.c: thrd_sleep returns 0 on success, a negative
  value on failure.  Testing against thrd_success is incorrect.

- tst-tss-basic.c: tss_set is incorrectly checkd for a non-0
  value.  The test should test aginst C11 threads error codes.
  This isn't catched because thrd_success is defined as 0.

Note that all three tests fail on FreeBSD, which defines all mutex type
values, as well as all C11 threads error codes with non-0 values.

323592fdc9 y2038: nptl: Convert pthread_cond_{clock|timed}wait to support 64 bit time
The pthread_cond_clockwait and pthread_cond_timedwait have been converted
to support 64 bit time.

This change introduces new futex_abstimed_wait_cancelable64 function in
./sysdeps/nptl/futex-helpers.c, which uses futex_time64 where possible
and tries to replace low-level preprocessor macros from
lowlevellock-futex.h
The pthread_cond_{clock|timed}wait only accepts absolute time. Moreover,
there is no need to check for NULL passed as *abstime pointer as
__pthread_cond_wait_common() always passes non-NULL struct __timespec64
pointer to futex_abstimed_wait_cancellable64().

For systems with __TIMESIZE != 64 && __WORDSIZE == 32:
- Conversions between 64 bit time to 32 bit are necessary
- Redirection to __pthread_cond_{clock|timed}wait64 will provide support
  for 64 bit time

The futex_abstimed_wait_cancelable64 function has been put into a separate
file on the purpose - to avoid issues apparent on the m68k architecture
related to small number of available registers (there is not enough
registers to put all necessary arguments in them if the above function
would be added to futex-internal.h with __always_inline attribute).

In fact - new function - namely __futex_abstimed_wait_cancellable32 is
used to reduce number of needed registers (as some in-register values are
stored on the stack when function call is made).

Build tests:
./src/scripts/build-many-glibcs.py glibcs

Run-time tests:
- Run specific tests on ARM/x86 32bit systems (qemu):
  https://github.com/lmajewski/meta-y2038 and run tests:
  https://github.com/lmajewski/y2038-tests/commits/master

Above tests were performed with Y2038 redirection applied as well as without
to test the proper usage of both __pthread_cond_{clock|timed}wait64 and
__pthread_cond_{clock|timed}wait.

2b09ebeee7 RISC-V: Use 64-bit time_t and off_t for RV32 and RV64
Using the original glibc headers under bits/ let's make small
modifications to use 64-bit time_t and off_t for both RV32 and RV64.

For the typesizes.h, here are justifications for the changes from the
generic version (based on Arnd's very helpful feedback):
- All the !__USE_FILE_OFFSET64 types (__off_t, __ino_t, __rlim_t, ...)
  are changed to match the 64-bit replacements.

- __time_t is defined to 64 bit, but no __time64_t is added. This makes
  sense as we don't have the time64 support for other 32-bit
  architectures yet, and it will be easy to change when that happens.

- __suseconds_t is 64-bit. This matches what we use the kernel ABI for
  the few drivers that are relying on 'struct timeval' input arguments
  in ioctl, as well as the adjtimex system call. It means that timeval
  has to be defined without the padding, unlike timespec, which needs
  padding.
