Use them everywhere possible. This lead to significant cleanup in the API routines and eliminated some of the same code from the POSIX API. At this point, the SuperCore keeps time in POSIX timespec format properly from 1970. You just cannot set it before 1988 in keeping with RTEMS traditional behavior. * score/include/rtems/score/timespec.h, score/src/timespecaddto.c, score/src/timespecfromticks.c, score/src/timespecisvalid.c, score/src/timespeclessthan.c, score/src/timespecsubtract.c, score/src/timespectoticks.c: New files. * posix/src/posixintervaltotimespec.c, posix/src/posixtimespecsubtract.c, posix/src/posixtimespectointerval.c: Removed.
