[1/5] time: Introduce glibc's internal struct __itimerspec64

  This change provides the glibc's internal struct itimerspec representation,
which is explicitly supporting 64 bit time (by using struct __timespec64).

Such representation is necessary to provide correct time after Y2038
(time_t overflow) on devides with __TIMESIZE == 32.

Gentle ping.

Ok, __timespec64 already handles both the padding and endianess.
