y2038: Convert aio_suspend to support 64 bit time
The aio_suspend function has been converted to support 64 bit time. This change uses (in aio_misc.h): - __futex_abstimed_wait64 (instead of futex_reltimed_wait) - __futex_abstimed_wait_cancellable64 (instead of futex_reltimed_wait_cancellable) from ./sysdeps/nptl/futex-helpers.h The aio_suspend() accepts relative timeout, which then is converted to absolute one. The i686-gnu port (HURD) do not define DONT_NEED_AIO_MISC_COND and as it doesn't (yet) support 64 bit time it uses not converted pthread_cond_timedwait(). The __aio_suspend() is supposed to be run on ports with __TIMESIZE !=64 and __WORDSIZE==32. It internally utilizes __aio_suspend_time64() and hence the conversion from 32 bit struct timespec to 64 bit one is required. For ports supporting 64 bit time the __aio_suspend_time64() will be used either via alias (to __aio_suspend when __TIMESIZE==64) or redirection (when -D_TIME_BITS=64 is passed).
