* ChangeLog, libcsupport/src/malloc.c,
	libcsupport/src/mallocfreespace.c, sapi/include/confdefs.h,
	score/Makefile.am, score/preinstall.am: malloc never blocks so the
	Region Manager is quite heavy for implementing this. This patch
	implements the C Program Heap directly in terms of the new Protected
	Heap handler. This handler is a direct use of a SuperCore Heap in
	conjunction with the Allocator Mutex used internally by RTEMS. This
	saves 3184 bytes on most SPARC test executables.
	* score/include/rtems/score/protectedheap.h, score/src/pheapallocate.c,
	score/src/pheapallocatealigned.c, score/src/pheapextend.c,
	score/src/pheapfree.c, score/src/pheapgetblocksize.c,
	score/src/pheapgetfreeinfo.c, score/src/pheapgetinfo.c,
	score/src/pheapinit.c, score/src/pheapresizeblock.c,
	score/src/pheapwalk.c: New files.
