	PR 408/filesystem
	* score/Makefile.am, score/include/rtems/score/thread.h: Added
	sync() service. As part of adding this service, the
	new RTEMS service rtems_iterate_over_all_threads() was also added.
	This new service makes it easier to iterate over all the
	tasks/threads in a system and perform an action on them.
	* score/src/iterateoverthreads.c: New file.
	* ChangeLog: Fixed screwup.
