time: Introduce function to check correctness of nanoseconds value
The valid_nanoseconds () static inline function has been introduced to check if nanoseconds value is in the correct range - greater or equal to zero and less than 1000000000. The explicit #include <time.h> has been added to files where it was missing. The __syscall_slong_t type for ns has been used to avoid issues on x32. Tested with: - scripts/build-many-glibcs.py - make PARALLELMFLAGS="-j12" && make PARALLELMFLAGS="-j12" xcheck on x86_64
