* 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.
