Make rtems_task_get_affinity() and rtems_task_set_affinity() available
on non-SMP configurations.  Allow larger CPU sets.

- *  @brief RTEMS Get Task Affinity

+ * @param[in] id Identifier of the task.  Use @ref RTEMS_SELF to select the
+ * executing task.
+ * @param[in] cpusetsize Size of the specified affinity set buffer in

+ * @param[out] cpuset The current processor affinity set of the task.  A set
+ * bit in the affinity set means that the task can execute on this processor
+ * and a cleared bit means the opposite.
  *
- * @param[in] id is the thread to extract
- * @param[in] cpusetsize is the size of the cpuset
- * @param[out] cpuset is the tasks affinity cpuset

+ * @retval RTEMS_INVALID_ID Invalid task identifier.
+ * @retval RTEMS_INVALID_NUMBER The affinity set buffer is too small for the
