Lukasz Majewski 390b5a4727 y2038: include: Move struct __timespec64 definition to a separate file
The struct __timespec64's definition has been moved from ./include/time.h to
./include/struct___timespec64.h.

This change would prevent from polluting other glibc namespaces (when
headers are modified to support 64 bit time on architectures with
__WORDSIZE==32).

Now it is possible to just include definition of this particular structure
when needed.

/* The glibc Y2038-proof struct __timespec64 structure for a time value.
To keep things Posix-ish, we keep the nanoseconds field a 32-bit
signed long, but since the Linux field is a 64-bit signed int, we
pad our tv_nsec with a 32-bit unnamed bit-field padding.
As a general rule the Linux kernel is ignoring upper 32 bits of
tv_nsec field. */
