[PATCH 0/4] Progress toward absolute time intervals

[Gedare Bloom]

These patches move forward toward a goal to provide support
for the CLOCK_ABSTIME in POSIX. The first service targeted
is the clock_nanosleep, with others to follow. The bulk of
changes here are to add separate watchdog disciplines for
relative and absolute time intervals. This adds timeout
fields to the threadq context, moves WATCHDOG_NO_TIMEOUT
into the new Watchdog_Discipline, promotes Watchdog_Interval
to 64 bits.

Gedare Bloom (4):
  cpukit: Add and use Watchdog_Discipline.
  posix: add clock_nanosleep and tests
  cpukit/rtems: fix return type mismatch for _TOD_To_seconds
  score: use 64-bit watchdog intervals
