c-user: Generate task manager documentation

The documentation is a consolidation of the comments in Doxygen markup
and the documentation sources in Sphinx markup.  The documentation was
transfered to interface specification items.  The documentation source
files were generated from the items by a script.

+* :ref:`InterfaceRtemsTaskCreate` - Creates a task.
 
-- :ref:`rtems_task_self`
+* :ref:`InterfaceRtemsTaskConstruct` - Constructs a task from the specified
+  task configuration.
 
-- :ref:`rtems_task_start`
+* :ref:`InterfaceRtemsTaskIdent` - Identifies a task by the object name.
 
-- :ref:`rtems_task_restart`
+* :ref:`InterfaceRtemsTaskSelf` - Gets the task identifier of the calling task.
 
-- :ref:`rtems_task_delete`
+* :ref:`InterfaceRtemsTaskStart` - Starts the task.
 
-- :ref:`rtems_task_exit`
+* :ref:`InterfaceRtemsTaskRestart` - Restarts the task.
 
-- :ref:`rtems_task_suspend`
+* :ref:`InterfaceRtemsTaskDelete` - Deletes the task.
 
-- :ref:`rtems_task_resume`
+* :ref:`InterfaceRtemsTaskExit` - Deletes the calling task.
 
-- :ref:`rtems_task_is_suspended`
+* :ref:`InterfaceRtemsTaskSuspend` - Suspends the task.
 
-- :ref:`rtems_task_set_priority`
+* :ref:`InterfaceRtemsTaskResume` - Resumes the task.
 
-- :ref:`rtems_task_get_priority`
+* :ref:`InterfaceRtemsTaskIsSuspended` - Checks if the task is suspended.
 
-- :ref:`rtems_task_mode`
+* :ref:`InterfaceRtemsTaskSetPriority` - Sets the real priority or gets the
+  current priority of the task.
 
-- :ref:`rtems_task_wake_after`
+* :ref:`InterfaceRtemsTaskGetPriority` - Gets the current priority of the task
+  with respect to the scheduler.
 
-- :ref:`rtems_task_wake_when`
+* :ref:`InterfaceRtemsTaskMode` - Gets and optionally sets the mode of the
+  calling task.
 
-- :ref:`rtems_task_get_scheduler`
+* :ref:`InterfaceRtemsTaskWakeAfter` - Wakes up after an interval in
+  :term:`clock ticks <clock tick>` or yields the processor.
 
-- :ref:`rtems_task_set_scheduler`
+* :ref:`InterfaceRtemsTaskWakeWhen` - Wakes up when specified.
 
-- :ref:`rtems_task_get_affinity`
+* :ref:`InterfaceRtemsTaskGetScheduler` - Gets the home scheduler of the task.
 
-- :ref:`rtems_task_set_affinity`
+* :ref:`InterfaceRtemsTaskSetScheduler` - Sets the home scheduler for the task.
 
-- :ref:`rtems_task_iterate`
+* :ref:`InterfaceRtemsTaskGetAffinity` - Gets the processor affinity of the
+  task.
+
+* :ref:`InterfaceRtemsTaskSetAffinity` - Sets the processor affinity of the
