hooks: Move HOOK_INIT to after task switching.

This commit changes the way in which tasks are started.  Instead of
having all tasks marked as ready to run upon initialization, only the
hooks task is marked as ready to run.  HOOK_INITs are now run at the
beginning of the hooks task.  After the HOOK_INITs, the hooks task calls
back to enable the rest of the tasks, reschedules, and proceeds as
usual.  This also allows the removal of checks for task_start_called().
