Bring in timespce_get form NetBSD.
Bring in the functionality for timespec_get from NetBSD. I've lightly edited the .c file to remove _DIAGASSERT because FreeBSD doesn't have that functionality and the typical #define'ing it to assert isn't right here. The man page is verbatim from NetBSD, but will be revised as part of a larger cleanup of the time man pages (they are inconsistent and vague in all the wrong places).
