	score/src/userext.c: Switch to newlib reentrancy extension being
	installed in the initial set instead of using rtems_extension_create.
	While implementing this, noticed that user extensions and chain code
	had multiple functions in a single file which is not desirable in the
	SuperCore and API portions of RTEMS, so split these into multiple
	files with one function per file. Also noticed that some of user
	extension code was inlined for no particular reason so moved that to
	C bodies.  Split executive shutdown from initialization since not
	every application shuts down.  Moved __fini call to executive shutdown
	to be more symmetrical with where it is called at startup.
