Introduce time64 support.
This patch introduces *time64 syscalls support for uClibc-ng. Currently the redirection of syscalls to their *time64 analogs is fully supported for 32bit ARM (ARMv5, ARMv6, ARMv7). The main changes that take effect when time64 feature is enabled are: - sizeof(time_t) is 8. - There is a possibility os setting date beyond year 2038. - some syscalls are redirected: clock_adjtime -> clock_adjtime64 clock_getres -> clock_getres_time64 clock_gettime -> clock_gettime64 clock_nanosleep -> clock_nanosleep_time64 clock_settime -> clock_settime64 futex -> futex_time64 mq_timedreceive -> mq_timedreceive_time64 mq_timedsend -> mq_timedsend_time64 ppoll -> ppoll_time64 pselect6 -> pselect6_time64 recvmmsg -> recvmmsg_time64 rt_sigtimedwait -> rt_sigtimedwait_time64 sched_rr_get_interval -> sched_rr_get_interval_time64 semtimedop -> semtimedop_time64 timer_gettime -> timer_gettime64 timer_settime -> timer_settime64 timerfd_gettime -> timerfd_gettime64 timerfd_settime -> timerfd_settime64 utimensat -> utimensat_time64. - settimeofday uses clock_settime (like in glibc/musl). - gettimeofday uses clock_gettime (like in glibc/musl). - nanosleep uses clock_nanosleep (like in glibc/musl). - There are some fixes in data structures used by libc and kernel for correct data handling both with and without enabled time64 support.
