[PATCH v2 04/15] posix timers:Introduce the 64bit methods with timespec64 type for k_clock structure

[Baolin Wang]

This patch introduces the new methods with timespec64/itimerspec64 type for k_clcok
structure,converts the timepsec type to timespec64 type in k_clock structure and
converts the itimerspec type to itimerspec64 type to ready for 2038 issue.

I asked you last time to provide a conversion for a single instance
first and I gave you even step by step instructions.

But you insist on resending the whole mess in one go. Try again.

Single function, single syscall. Not a wholesale conversion of the
world and some more.
