All the implementations of NsecToTimespec and NsecToTimeval were the same other than types. Write a single version that uses GOARCH/GOOS-specific setTimespec and setTimeval functions to handle the types. The logic in NsecToTimespec and NsecToTimeval caused times before 1970 to have a negative usec/nsec. The Linux kernel requires that usec contain a positive number; for consistency, we do this for both NsecToTimespec and NsecToTimeval.
