Add 32bit time64 syscalls for arm, mips32, ppc32 and x86
This patch adds sycall wrappers for the following syscalls which
use a 64bit time_t on 32bit arches: gettime64, settime64,
clock_getres_time64, clock_nanosleep_time64, timer_gettime64,
timer_settime64, timerfd_gettime64, timerfd_settime64,
utimensat_time64, pselect6_time64, ppoll_time64, recvmmsg_time64,
mq_timedsend_time64, mq_timedreceive_time64, semtimedop_time64,
rt_sigtimedwait_time64, futex_time64 and sched_rr_get_interval_time64.
Still missing are clock_adjtime64 and io_pgetevents_time64.
For the more complicated syscalls futex[_time64], pselect6[_time64]
and ppoll[_time64] there are shared pre and/or post helper functions.
Other functions just have their own PRE and POST handler.
Note that the vki_timespec64 struct really is the struct as used by
by glibc (it internally translates a 32bit timespec struct to a 64bit
timespec64 struct before passing it to any of the time64 syscalls).
The kernel uses a 64-bit signed int, but is ignoring the upper 32 bits
of the tv_nsec field. It does always write the full struct though.
So avoid checking the padding is only needed for PRE_MEM_READ.
There are two helper pre_read_timespec64 and pre_read_itimerspec64
to check the new structs.
Tested on i686, armv7hl, ppc64le, aarch64, s390x and x86_64 (only the first 2
have the new time64 syscalls).
