[PATCH 0/5] v2: Progress toward absolute time intervals

[Gedare Bloom]

These patches move forward toward a goal to provide support
for the CLOCK_ABSTIME in POSIX. Version 2 includes fixes to
address Sebastian's review on version 1. In addition to the
clock_nanosleep service, now I also include cond_timedwait.
Timeout fields are in the threadq context, with a new type
Watchdog_Discipline and corresponding relative, absolute,
and now WATCHDOG_NO_TIMEOUT uses this type. For backward
compatibility, the threadq enqueue interprets relative
discipline with a timeout of 0 as a WATCHDOG_NO_TIMEOUT.

v2:
* revert back to 32-bit watchdog intervals.
* consolidate functions for setting context timeout params.
* add abstime for cond_timewait (patches 4/5 and 5/5).
* fix switch logic and local var use in threadq enqueue.

Gedare Bloom (5):
  cpukit: Add and use Watchdog_Discipline.
  posix: add clock_nanosleep and tests
  cpukit/rtems: fix return type mismatch for _TOD_To_seconds
  posix: refactor cond wait support to defer abstime conversion
  posix: cond_timedwait remember and use clock from condattr
